Quadruple 2-Line To 1-Line Data Selectors/Multiplexers

 

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.

Features

  • Buffered Inputs and Outputs
  • Three Speed/Power Ranges Available
  • Applications
    • Expand Any Data Input Point
    • Multiplex Dual Data Buses
    • Generate Four Functions of Two Variables (One Variable Is Common)
    • Source Programmable Counters
