DM54150 数据手册

June 1989

54150/DM54150/DM74150,

54151A/DM54151A/DM74151A

Data Selectors/Multiplexers

General Description

Features

150 selects one-of-sixteen data lines

151A selects one-of-eight data lines

Performs parallel-to-serial conversion

Permits multiplexing from N lines to one line

Also for use as Boolean function generator

These data selectors/multiplexers contain full on-chip de-

coding to select the desired data source. The 150 selects

one-of-sixteen data sources; the 151A selects one-of-eight

data sources. The 150 and 151A have 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

(as applicable) low.

Typical average propagation delay time, data input to W

output

The 151A features complementary W and Y outputs, where-

as the 150 has an inverted (W) output only.

150

151A

11 ns

9 ns

The 151A incorporates address buffers which have sym-

metrical propagation delay times through the complementa-

ry paths. This reduces the possibility of transients occurring

at the output(s) due to changes made at the select inputs,

even when the 151A outputs are enabled (i.e., strobe low).

Typical power dissipation

150 200 mW

151A 135 mW

Alternate Military/Aerospace device (54150, 54151A) is

available. Contact a National Semiconductor Sales Of-

fice/Distributor for specifications.
