CY74FCT16646ETPVC

Overview

The CY74FCT16646ETPVC is a registered bus transceiver from the FCT series, manufactured by Cypress Semiconductor Corp. It features two functional units, each handling 8 bits of data, resulting in a total 16-bit width. The device utilizes CMOS technology and provides true outputs. It is housed in a 56-pin SSOP package with a 0.300-inch body width and 0.025-inch pitch. This component serves as a high-performance logic IC for bus driver and transceiver applications.

Feature Summary

• Provides registered data storage capability at the bus interface to improve signal integrity
• Supports bidirectional data transfer between buses using CMOS technology
• Integrates two independent 8-bit functional units within a single package

Applications

• Bus driver circuits requiring registered output buffering
• Bidirectional bus transceivers in data communication systems
• Logic integrated circuit implementations for parallel data transfer

Procurement Notes

Verify the specific suffix 'TPVC' corresponds to the SSOP-56 package and bulk tape configuration when sourcing. Confirm the manufacturer origin, noting that Infineon Technologies now holds the product line following the acquisition of Cypress Semiconductor. Ensure documentation references the correct active lifecycle status for current production support.

Selection Notes

Select this component when a 16-bit registered transceiver is required for system interconnects. The FCT series offers compatibility with standard logic families while providing improved performance characteristics. Consider the 56-pin SSOP footprint for PCB layout constraints and verify voltage level requirements match the target application's power supply specifications.

Part Context

This part belongs to the 74FCT series of high-speed CMOS logic devices. Cypress Semiconductor developed this family for applications demanding fast switching speeds and low power consumption. The company was later acquired by Infineon Technologies, which continues to support these legacy logic products through its semiconductor division.

Replacement Considerations

Check for direct pin-compatible substitutes within the 74FCT16646 family from Infineon or other authorized manufacturers. Verify electrical parameters such as propagation delay and drive strength against original specifications before substitution.
