54157/DM54157/DM74157

Quad 2-Line to 1-Line Data Selectors/Multiplexers

General Description

Features

Buffered inputs and outputs

These data selectors/multiplexers contain inverters and

drivers to supply full on-chip data selection to the four out-

put gates. A separate strobe input is provided. A 4-bit word

is selected from one of two sources and is routed to the four

outputs.

Typical propagation time 9 ns

Typical power dissipation 150 mW

Alternate Military/Aerospace device (54157) is avail-

able. Contact a National Semiconductor Sales Office/

Distributor for specifications.

Applications

Expand any data input point

Multiplex dual data buses

Generate four functions of two variables (one variable

is common)

Source programmable counters
