CY74FCT16245TPVCT

Overview

The CY74FCT16245TPVCT is a dual 8-bit bus transceiver from the FCT series, manufactured by Cypress Semiconductor Corp. It features true output polarity and operates within an industrial temperature range of -40°C to +85°C. The device utilizes a 48-pin TSSOP package with a shrink pitch. Key electrical parameters include a propagation delay of 7 ns under a 50 pF load condition. It supports 3-state outputs and is designed for CMOS logic applications requiring high-speed bidirectional data transfer.

Feature Summary

• Provides bidirectional data transmission across two independent 8-bit channels
• Features 3-state outputs to facilitate bus line management
• Supports live insertion via power-off disable functionality

Applications

• High-speed data routing in computer systems
• Memory buffer interfaces
• Control signal distribution networks

Procurement Notes

Verify the specific suffix 'TPVCT' against official Cypress documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure the component matches the required TSSOP-48 form factor and that the manufacturer designation aligns with current corporate ownership structures following industry acquisitions.

Selection Notes

Select this component when designing systems requiring dual-channel 16-bit wide data paths with moderate speed requirements. The FCT technology offers a balance between performance and power consumption suitable for standard 5V logic environments. Consider the 7 ns delay relative to system clock speeds to ensure timing margins are met without excessive overshoot or undershoot issues.

Part Context

This part belongs to the broader 74FCT family of high-speed CMOS logic devices originally developed by Fairchild Semiconductor and later acquired by Cypress. The CY74FCT16245 variant specifically addresses the need for 16-bit wide bus interfacing in compact surface-mount packages, serving as a critical interface element between microprocessors and peripheral memory banks.

Replacement Considerations

Cross-reference with IDT74FCT16245 or TI SN74FCT16245 equivalents. Verify pin-to-pin compatibility and electrical characteristics before substitution. Note that manufacturer transitions may affect long-term availability and minor parameter variations.
