74VHCT157A

The 74VHCT157A is an high-speed CMOS QUAD 2-CHANNEL MULTIPLEXER fabricated with sub-micron silicon gate and double-layer metal wiring C²MOS technology.

It consists of four 2-input digital multiplexers of the 74VHCT157A with common select and strobe inputs.It is a non-inverting multiplexer.When the STROBE</a> input is held high,selection of data is inhibited and all the outputs become low.The decoding determines whether the A or B inputs SELECT get routed to their corresponding Y outputs.

Power down protection of the 74VHCT157A is provided on all inputs and outputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage.This device can be used to interface 5V to 3V.All inputs and outputs are equipped with protection circuits against static discharge,giving them 2KV ESD immunity and transient excess voltage.
