Application Scenarios & Design Considerations

QUADRUPLE 2-LINE TO 1-LINE DATA SELECTORS/MULTIPLEXERS

Alternative Part Number

  • 74AHCT157PW,118 --: Quad 2-input multiplexer with the same AHCT logic family and function, offered in a TSSOP package by a different manufacturer, making it a direct functional replacement.
  • MC74VHCT157ADTR2G --: Quad 2-line to 1-line data selector/multiplexer with TTL-compatible inputs and similar speed, suitable as a cross-manufacturer alternative.
  • CD74HCT157M96 --: HCT-family quad 2-input multiplexer from the same vendor with equivalent logic function, useful when a different package or series variant is acceptable.
  • MC74AHCT157ADTR2G --: Quad 2-input multiplexer with AHCT-compatible TTL input levels, TSSOP package, pin-compatible alternative.
  • CD74AHCT157M96 --: Same AHCT quad multiplexer function from TI in SOIC package; usable if board layout allows SOIC instead of TSSOP.
