DescriptionQUAD 2 CHANNEL MULTIPLEXER
Datasheet Summary with AI

The 74VHC157 is a high-speed CMOS QUAD 2-CHANNEL MULTIPLEXER with preliminary data released in June 1999.
It has a high-speed of tPD=4.1ns (TYP.) at VCC=5V and low power dissipation with ICC=4µA (MAX.) at TA=25oC.
It also has high noise immunity, power down protection on inputs, symmetrical output impedance, and balanced propagation delays.
The device can be used to interface 5V to 3V and has improved latch-up immunity and low noise.
It consists of four 2-input digital multiplexers with common select and strobe inputs.
The device has power down protection on all inputs and can accept 0 to 7V on inputs with no regard to the supply voltage.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
The device is pin and function compatible with 74 series 157 and has improved latch-up immunity.
It has dynamic switching characteristics and recommended operating conditions.
The device also has absolute maximum ratings, input equivalent circuit, truth table, pin description, logic diagram, and test circuit.
The device is part of the STMicroelectronics group of companies.
