Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing lot details against current datasheets. Check for obsolescence notices or lifecycle changes from Renesas Electronics, as IDT logic products may have transitioned manufacturers. Ensure packaging specifications match design requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when 16-bit parallel data transfer with internal latching is required. It serves as a high-speed, low-power replacement for older ABT functions. Consider the TSSOP-56 package dimensions for PCB layout. Verify that the 5V operating voltage aligns with the target system power rails and that the propagation delay meets timing constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74FCT family of high-speed CMOS logic devices. It is functionally similar to other 16-bit latched transceivers like the 74FCT16543 variants from different manufacturers. The device integrates latch control and direction control signals to manage bidirectional data flow on a shared bus structure while maintaining data integrity during transitions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Cross-reference with CY74FCT16543ATPACT from Texas Instruments/Cypress for equivalent registered bus transceiver functionality. Verify pinout compatibility and electrical parameter alignment before substitution.
