Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' against the manufacturer's current datasheet to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status as manufacturing processes evolve. Check for active obsolescence notices or end-of-life declarations prior to finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring registered 16-bit data latching with bidirectional control. Ensure the design accommodates the 4.5V to 5.5V supply requirement. Verify that the TSSOP-56 package dimensions fit the PCB layout constraints and thermal management requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74FCT family, which combines Fast CMOS speed with standard TTL-compatible voltage levels. The 162646 designation indicates a registered transceiver configuration, distinct from unregistered buffers or simple drivers in the same product line.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Consult official substitution guides for equivalent registered transceivers if this specific package variant is unavailable. Verify that any substitute maintains the same 16-bit width, registration feature, and TSSOP-56 footprint.
