DM74S158 - Quad 1 of 2 Line Data Selector/Multiplexer

Download the DM74S158 datasheet PDF. This datasheet also covers the DM74S157 variant, as both devices belong to the same quad 1 of 2 line data selector/multiplexer family and are provided as variant models within a single manufacturer datasheet.

General Description

These data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four output 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.

DM74S157 • DM74S158 Quad 1 of 2 Line Data Selector/Multiplexer August 1986 Revised April 2000 DM74S157 • DM74S158 Quad 1 of 2 Line Data Selector/Multiplexer General Description These data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four output 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 DM74S157 presents true data whereas the DM74S158 presents inverted data to minimize propagation delay time.
