SN54ALS157A - Quadruple 1-of-2 Data Selectors/Multiplexers

Download the SN54ALS157A datasheet PDF. This datasheet also covers the SN54ALS158 variant, as both devices belong to the same quadruple 1-of-2 data selectors/multiplexers family and are provided as variant models within a single manufacturer datasheet.

Description

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

A separate strobe (G) input is provided.

A 4-bit word is selected from one of two sources and is routed to the four outputs.

A separate strobe (G) input is provided. A 4-bit word is selected from one of two sources and is routed to the four outputs. The ′ALS157A and SN74AS157 present true data. The ′ALS158 and SN74AS158 present inverted data to minimize propagation delay time.
