DM74LS157 - Quad 2-Line to 1-Line Data Selectors/Multiplexers

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.

DM74LS157 • DM74LS158 Quad 2-Line to 1-Line Data Selectors/Multiplexers September 1986 Revised April 2000 DM74LS157 • DM74LS158 Quad 2-Line to 1-Line Data Selectors/Multiplexers 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 DM74LS157 presents true data whereas the DM74LS158 presents inverted data to minimize propagation delay time.
