input is held high selection of data is inhibited and

all the outputs become low. The SELECT

decoding determines whether the A or B inputs

get routed to their corresponding Y outputs.

Power down protection is provided on all inputs

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.

DESCRIPTION

The 74VHC157 is an advanced high-speed

CMOS QUAD 2-CHANNEL MULTIPLEXER

fabricated with sub-micron silicon gate and

double-layer metal wiring C MOS technology.

It consists of four 2-input digital multiplexer with

common select and strobe inputs. It is a

non-inverting multiplexer. When the STROBE
