Application Scenarios & Design Considerations

QUADRUPLE 2-INPUT MULTIPLEXERS WITH STORAGE

Alternative Part Number

  • 74LS298N --: Functionally equivalent quad 2-input multiplexer with storage, LS TTL logic, DIP package; widely available and pin-compatible in most designs.
  • MC74HC298N --: CMOS quad 2-input multiplexer with storage in DIP package; lower power alternative with similar logic function, though check voltage and drive compatibility.
  • CD74HCT298E --: HCT CMOS quad 2-input multiplexer with storage, TTL-compatible inputs, DIP package; suitable drop-in style replacement with attention to timing.
