Application Scenarios & Design Considerations

QUAD 2-INPUT MULTIPLEXER

Alternative Part Number

  • DM74LS157N --: Pin-compatible quad 2-to-1 multiplexer in the same LS TTL family with equivalent logic function and timing.
  • MC74LS157N --: Direct functional equivalent quad 2-line to 1-line data selector/multiplexer with matching pinout and LS TTL levels.
  • SN74HC157N --: Same multiplexer function and pinout in HC CMOS family, usable where higher speed and lower power are acceptable.
  • 74LS157PC --: Same 74LS157 function and pinout from an alternate vendor, widely available and drop-in compatible for most designs.
