DM74S151

1-of-8 Data Selector/Multiplexer

with Complementary Outputs

General Description

These data selectors/multiplexers contain full on-chip

decoding

to

select

the

desired

data

source.

The

DM74S151

selects

one-of-eight

data

sources.

The

DM74S151 has a strobe input which must be at a low logic

level to enable these devices. A high level at the strobe

forces the W output HIGH and the Y output LOW.

The DM74S151 features complementary W and Y outputs.

Features

s Select one-of-eight data lines

s Performs parallel-to-serial conversion

s Permits multiplexing from N lines to one line

s Also for use as Boolean function generator

s Typical average propagation delay time, data input to W

output 4.5 ns

s Typical power dissipation 225 mW
