CY74FCT162652CTPVC

Overview

The CY74FCT162652CTPVC is a 16-bit registered bus transceiver manufactured by Texas Instruments, operating within the FCT logic family. It features a dual 8-bit configuration housed in a 56-pin SSOP package. The device supports bidirectional data transfer with independent direction control and utilizes TTL-compatible input and output levels. It operates on a supply voltage range of 4.5V to 5.5V, ensuring compatibility with standard 5V CMOS systems while providing high-speed performance suitable for complex digital interfaces.

Feature Summary

• Integrates two independent 8-bit registers to facilitate simultaneous data storage and transmission across separate channels.
• Provides bidirectional data flow capability controlled by dedicated direction pins for flexible system architecture integration.
• Features TTL-compatible input thresholds allowing direct interfacing with various logic families without additional level shifting.

Applications

• High-speed parallel data buffering in computer memory subsystems
• Bidirectional interface circuits between microprocessors and peripheral devices
• Data acquisition systems requiring synchronized signal registration

Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by Texas Instruments despite the historical association with Cypress Semiconductor. Confirm the specific suffix 'TPVC' corresponds to the SSOP-56 surface mount package variant. Ensure compliance with RoHS standards and check for lead-free certification if required by your assembly process specifications.

Selection Notes

Select this component when designing systems that require registered data latching alongside bidirectional bus driving capabilities. It is appropriate for applications needing isolation between source and load during data transitions. Consider the thermal dissipation characteristics and ensure adequate PCB layout for the SSOP-56 footprint to maintain signal integrity at high switching frequencies.

Part Context

This part belongs to the FCT (Fast CMOS Technology) series, designed to bridge the speed gap between standard CMOS and Schottky TTL logic. The 162652 variant specifically addresses needs for multi-byte data handling in embedded controllers. Its registration feature helps mitigate race conditions in synchronous digital designs, making it a staple in legacy and industrial control hardware architectures.

Replacement Considerations

The CD74FCT162652CTSM from Intersil/Renesas serves as a functional equivalent with identical pinout and electrical characteristics. Verify package tolerance differences between SSOP variants before substitution. Cross-reference datasheets to confirm matching propagation delays and drive strengths for critical timing paths.
