Application Scenarios & Design Considerations

3.3V CMOS OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS AND 5 VOLT TOLERANT I/O

Alternative Part Number

  • SN74LVC245ADW --: Pin-compatible octal bus transceiver in the same LVC family with equivalent 3.3V logic levels and SOIC-20 package, widely available and a direct functional drop-in.
  • MC74LVC245ADWR2G --: Same LVC245 octal transceiver function with matching pinout and SOIC-20 wide-body package, offering comparable speed and drive characteristics.
  • 74LVC245APW --: Equivalent LVC245 bus transceiver with identical logic function and pinout; TSSOP package option is suitable when board layout allows a slightly different footprint.
  • MC74LVC245ADWR2 --: LVC octal bus transceiver with the same voltage range and drive capability, available in SOIC-20 wide body; suitable functional substitute when IDT parts are unavailable.
