CY74FCT16952ATPVC

Overview

The CY74FCT16952ATPVC is a registered bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features two independent circuits, each handling eight bits of data, totaling sixteen channels. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output levels. Key electrical parameters include a propagation delay of 10 ns, low-level output current of 64 mA, and high-level output current of -32 mA. It utilizes a 56-pin SSOP package and functions with non-inverting polarity.

Feature Summary

• Registered bus transceiver architecture providing data storage capability during transmission
• Dual independent control allowing separate direction management for each eight-bit channel
• Three-state outputs enabling direct connection to system buses without additional drivers

Applications

• High-speed parallel data transfer in computer systems
• Buffering and routing between microprocessors and memory modules
• I/O port expansion in embedded controller designs

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate tape-and-reel packaging versus tube quantities. Ensure the part number matches the exact SSOP-56 variant required for your PCB footprint.

Selection Notes

Select this component when designing systems requiring registered data latching alongside bidirectional bus driving capabilities. The FCT series offers CMOS compatibility with TTL thresholds, suitable for mixed-voltage environments operating at 5 V. Consider the 10 ns propagation delay and drive strength requirements against your specific signal integrity needs.

Part Context

This device belongs to the CY74FCT16952T family of registered transceivers. It serves as a bridge between internal logic and external bus structures, combining the speed of FCT technology with the data retention features of flip-flops. The component is widely used in legacy and industrial applications requiring robust 8-bit wide data paths.

Replacement Considerations

Check for updated revisions within the same FCT family. Verify pinout compatibility if substituting with other Cypress or Texas Instruments registered transceivers. Ensure the replacement maintains the 56-pin SSOP form factor and identical electrical characteristics.
