DM74LS157 • DM74LS158

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

General Description

Applications

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. The DM74LS157 presents true data whereas

the DM74LS158 presents inverted data to minimize propa-

gation delay time.

•

Expand any data input point

Multiplex dual data buses

Generate four functions of two variables

(one variable is common)

•

Source programmable counters

Features

■ Buffered inputs and outputs

■ Typical Propagation Time

DM74LS157 9 ns

DM74LS158 7 ns

■ Typical Power Dissipation

DM74LS157 49 mW

DM74LS158 24 mW
