Product Information

Features

Buffered Inputs and Outputs
Three Speed/Power Ranges Available

Description

These monolithic 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 '157, 'LS157, and 'S157 present true data whereas the 'LS158 and 'S158 present inverted data to minimize propagation delay time.

Device Uses

Expand Any Data Input Point
Multiplex Dual Data Buses
Generate Four Functions of Two Variables (One Variable Is Common)
Source Programmable Counters
