54LS157/DM54LS157/DM74LS157,

54LS158/DM54LS158/DM74LS158

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. The LS157 presents true data whereas the LS158

presents inverted data to minimize propagation delay time.

Typical Propagation Time

LS157 9 ns

LS158 7 ns

Typical Power Dissipation

LS157 49 mW

LS158 24 mW
