Logic ICs

Logic ICs are often referred to as ‘commodity ICs’ (integrated Circuits) are used in almost every piece of electrical and electronic equipment and circuitry across the world. Semiconductor ICs are widely used in development, design and manufacturing applications. RS offer an extensive range of high-quality standard logic semiconductors from leading brands including Texas Instruments, Toshiba, Nexperia, STMicroelectronics and ON Semiconductor.

Common Logic ICs types and their uses

Buffers transfer voltage from high to low output impedance circuits, acting as a barrier between source and load to prevent network disturbance. These devices can also be classified as as

  • Bus buffers
  • Buffer and Converter combinations
  • Buffer and Line Driver combinations

Bus Transceiver devices provide input/output signal control (i.e. bidirectional, unlike buffers,) to a shared data bus.

Counter ICs (also Shift Registers) typically comprises a number of connected cascading flip-flops, designed to register the number of times a process, clock or event occurs.

Decoders and Demultiplexers convert an input binary code to a single numeric output (decoders), or take information from a single input line and transmit it via one of the multiple outputs (demux)

Hex Inverters output opposite voltages to their input level, then invert the input signal to help clean up digital signal noise, add delay, shift levels, or convert between logic families.

Latch ICs offer high-speed, reliable protection for semiconductors against static discharge or excess voltage.

Logic Gates control signal flow via boolean functions (NOT, AND, OR, NAND, NOR), processing the signal into binary information.

Logic Level Shifters and Voltage Translators translate one logic level signal or voltage domain to another, enabling broader compatibility between different components / ICs.

Monostable Multivibrators produce a timed delay within circuits, for use as timers or pulse detectors.

Schmitt Trigger Inverters are active circuits that convert analog input signals to digital output.
