The integrated circuits section includes major groups of IC devices used in communication/interface, linear, logic, memory, microprocessor, optoelectronic, power management, etc. applications.
Circuits, Hybrid, Custom (101 Companies)
A Hybrid Integrated Circuit, (HIC) is a miniaturized electronic circuit constructed of individual devices, such as semiconductor devices and passives bonded to a substrate or printed circuit board (PCB). Hybrid circuits are often encapsulated in epoxy.
Devices that form complex multilayer circuits arranged by combining and interconnecting several passive and active semiconductor devices into a single package, which is screen printed and fired on a ceramic substrate.
Thin-film hybrids are hybrid circuits that are made by placing the substrate in a vacuum chamber and depositing films of conductive and resistive material on the entire substrate.
EEPROM is a type of non-volatile memory used in computers and other electronic devices to store small amounts of data that must be saved when power is removed. EEPROM such as flash memory, can store large amounts of static data.
A solid state integrated circuit amplifier employs external feedback for control of its transfer function or gain. It is similar to the operational amplifier but it also has differential output pins.
A bus is a subsystem that transfers data between computer components inside or between computers and can logically connect several peripherals over the same wires. Each bus defines its set of connectors to physically plug devices, cards or cables together
The portion of the receiver that converts the incoming signal to the intermediate frequency.
ICs that are commonly used in transferring data and signals over distances.
Chips for level-shifting, bus interface, plus Ethernet, USB, I2C, USART, and other communication interfaces.
ICs that select one of many data inputs and applies the source into a single channel. As a switch the IC functions as multiple input, single-output switch; or as a multiplexer controlling multiple inputs and selects a specific input to the single output.
Custom ICs are precisely designed to perform the specific circuit and gate functions needed for the application. Whereas Semicustom ICs are wafers that are deliberately left incomplete.
Change continuous signals to discrete digital format for further signal conditioning and processing. Commonly found in multimedia, data acquisition, etc. and virtually anywhere an analog signal has to be processed, stored, or transported in digital form.
Analog electronic filter, distinguished by the use of one or more active components. Active filters have two main advantages over passive filters. The amplifier can be used to shape the filter's response or buffer the filter from the components it drives.
A Wireless Amplifier is a device used to enhance the power or gain of a wireless signal over longer distances.
These ICs commonly contain components designed for audio and multimedia applications. Some internal components include audio amplifiers and speaker drivers. Other ICs allows the user to record, edit/modify and then playback audio.
A Clock Signal is a signal used to coordinate the actions of two or more circuits. A clock signal oscillates between a high and a low state, normally with a 50% duty cycle, and is usually in the form of a square wave.
A CODEC is a device or program capable of encoding and/or decoding a digital data stream or signal.
Digital-to-Analog converter (DAC or D-to-A) is a device for converting a digital (usually binary) code to an analog signal (current, voltage or electric charge).
Generally high-gain DC amplifiers designed to be used with external components to perform various mathematical functions or to provide a specific transfer function.
PLL is a control system using negative feedback. The circuit responds to both frequency and phase of the input signals, automatically raising or lowering the frequency of a controlled oscillator until it matches the reference in both frequency and phase.
A Prescaler is an electronic device that takes a frequency and reduces it by a pre-determined factor. For example; converts a 1 MHz signal to a 100kHz signal (scales the frequency by a factor of 10).
Sensor ICs consist of semiconductor circuit elements that are used to send information about its surrounding light, pressure, heat etc. in the form of electric signals or data. Family may consist of Hall effect, image and magnetic sensors.
Consumer Video ICs include chips that are suited for flat-panel displays, TVs DVD players and mobile phones.
Binary Counter is also called Binary Scaler. It is a counter which produces one output pulse for every two input pulses.
An isolating circuit used to avoid reaction of a driven circuit upon the corresponding driving circuit.

ICs that contain circuitry used to delay a signal for a predetermined length of time.
A Flip-Flop is a bistable multivibrator with two stable states serving as one bit of memory. Flip-Flop denotes non-transparent devices controlled by one or two control signals and/or a gate or clock signal. Flip-Flops require power and ground connections.
Logic Gate performs a logical operation on one or more logic inputs and produces a single logic output. The output is a logic-level value, and can connect to the input of other logic gates. They are primarily implemented using diodes or transistors.
A feedback loop used in a symmetrical digital circuit to retain a state. Two cross-coupled logic gates that store a pulse applied to one logic input until a pulse is applied to the other input: thus, the complementary information is stored in the latch.
Dynamic Random Access Memory (DRAM) stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically.
EEPROMs are floating-gate transistors arrays which are non-volatile memory chip used in computers to store small amounts of data that must be saved when power is removed. Flash memory EEPROMs store larger amounts of static data.
EPROM is a non-volatile computer memory chip that retains data when its power supply is switched off. An array of floating-gate transistors programmed by an electronic device that supplies higher voltages than those normally used in electronic circuits.
FIFOs are used in electronic circuits for buffering and flow control from hardware to software. In hardware form a FIFO has read and write pointers, storage and control logic. For FIFOs of non-trivial size a dual-port SRAM is used for reading and writing.
Non-volatile devices that find applications in portable devices such as digital cameras, cell phones, pagers, etc.
A Programmable Read-Only Memory (PROM) is a permanent digital memory chip that is programmed by the customer rather than by the chip manufacturer and used to store programs permanently.
ROM ICs are a class of storage media used in computers and other electronic devices. Since data stored in ROM cannot be very quickly or easily modified, these devices are mainly used to distribute firmware.
These memory-type ICs maintain their state until the next write operation, or when power is removed. SRAM memory ICs are used in system caches and video memory applications.
ICs used to provide control of various types of display circuitry.
An integrated component that uses a combination of electroluminescence and photoconductivity in the performance of all or at least a major portion of its intended function. Wavelengths considered may extend through visible into the infrared.
Laser Diode is a junction diode, consisting of positive and negative carrier regions with a pn transition region that emits electromagnetic radiation when injected electrons under forward bias recombine with holes in the vicinity of the junction.
Light-Emitting Diodes (LEDs) are semiconductor diodes that emit infrared, visible or ultraviolet light when electrical currents are applied in their forward directions. LEDs can be used as indicator lights, flashlights and area lighting.
Optocoupler is a light source and a light detector housed in a single package, sealed against outside light. An electrical signal applied to the light source changes the amount of light emitted and collected by the detector and coupled to the output.
Optoisolator is a coupling device consisting of a light sensor. Used for voltage and noise isolation between input and output while transferring the desired signal.
Photodetectors are sensors of light or other electromagnetic energy that senses incident illumination. A Photemitter is a device capable of emitting electrons when under the influence of light or other radiant energy.
