54LS158 - Quad 2-Line to 1-Line Data Selectors/Multiplexers

Download the 54LS158 datasheet PDF. This datasheet also covers the 54LS157 variant, as both devices belong to the same quad 2-line to 1-line data selectors/multiplexers 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 The LS157 presents true data whereas the LS158 present
