MC74VHC157

Quad 2-Channel Multiplexer

The MC74VHC157 is an advanced high−speed CMOS quad

2−channel multiplexer, fabricated with silicon gate CMOS

technology. It achieves high−speed operation similar to equivalent

Bipolar−Schottky TTL, while maintaining CMOS low−power

dissipation.

It consists of four 2−input digital multiplexers with common select

(S) and enable (E) inputs. When E is held High, selection of data is

inhibited and all the outputs go Low.

The select decoding determines whether the A or B inputs get routed

to the corresponding Y outputs.

The internal circuit is composed of three stages, including a buffer

output which provides high noise immunity and stable output. The

inputs tolerate voltages up to 7 V, allowing the interface of 5 V systems

to 3 V systems.
