CY74FCT16543CTPVC

Overview

The CY74FCT16543CTPVC is a registered bus transceiver from the Texas Instruments FCT logic series. It features two independent 8-bit circuits, providing a total of 16 channels in a non-inverting configuration. The device utilizes three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 56-pin SSOP package with a maximum propagation delay of 6.5 ns. The component supports low-level output currents of 64 mA and high-level output currents of -32 mA, functioning reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Registered data storage capability for latching input signals before transmission
• Independent output enable control for each direction of data flow
• High drive strength suitable for driving multiple loads on system buses

Applications

• Parallel data buffering in computer systems
• Clock distribution networks requiring signal registration
• Bus-oriented memory and I/O interface circuits

Procurement Notes

Verify the specific suffix 'CTPV' against official datasheets to confirm the exact package variant and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check current lifecycle status as this component may be discontinued or subject to obsolescence notices.

Selection Notes

Select this component when 16-bit registered transfer is required with FCT speed characteristics. Ensure the design accommodates the 56-pin SSOP footprint and thermal dissipation limits. Verify that the 4.5V to 5.5V operating range matches the target system power rails and that TTL-compatible input levels are utilized.

Part Context

This part belongs to the CY74FCT16543 family of registered bus transceivers. It serves as a bridge between microprocessors and peripheral devices, offering data retention through internal latches. The FCT series provides performance comparable to older technologies while maintaining CMOS power efficiency and compatibility with standard logic families.

Replacement Considerations

Consult official substitution guides for equivalent registered transceivers. Verify pinout compatibility and electrical parameter alignment before replacing.
