Application Scenarios & Design Considerations

OCTAL BUS TRANSCEIVERS WITH OPEN-COLLECTOR OUTPUTS

Alternative Part Number

  • 74F621N --: Same 74F621 octal bus transceiver function in a plastic DIP package; NXP is a second source for the F621 function with comparable speed and drive.
  • CY74FCT621TQCT --: FCT621T is a functionally equivalent octal bus transceiver with similar pinout and speed grade, suitable as a drop-in alternative in most designs.
  • 74F621PC --: Fairchild's 74F621 in PDIP offers the same octal transceiver function and is a widely available alternative to the TI military-grade part.
