CY74FCT16543TPVC

Overview

The CY74FCT16543TPVC is a 16-bit registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input and output levels. The device provides three-state outputs with a low-level output current of 64 mA and a high-level output current of -32 mA. It exhibits a propagation delay of 6.5 ns and functions as a non-inverting latched transceiver. The component is housed in a TSSOP-56 package and supports surface-mount installation.

Feature Summary

• Provides 16-bit data transmission capability through two independent 8-bit circuits
• Integrates registered latch functionality for data storage during transfer operations
• Delivers high drive strength suitable for demanding bus loading conditions

Applications

• High-speed parallel data bus interfacing in industrial systems
• Memory buffer applications requiring registered data holding
• I/O expansion modules in embedded controller architectures

Procurement Notes

Verify the specific suffix 'TPVC' against the official datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the TSSOP-56 form factor. Confirm that the logic family requirements align with the system's voltage and speed constraints before finalizing procurement.

Selection Notes

Select this component when a 16-bit width is required alongside internal data registration capabilities. The FCT logic family offers a balance of speed and drive strength appropriate for 5V systems. Consider the TSSOP-56 package dimensions if space constraints dictate the use of thin-shrink small-outline packaging.

Part Context

This part belongs to the Texas Instruments 74FCT logic family, designed for high-speed CMOS applications. It serves as a registered transceiver variant within the broader 74FCT16543 product line, providing enhanced data integrity compared to non-latched counterparts.
