CY74FCT16646TPVCT

Overview

The CY74FCT16646TPVCT is a registered bus transceiver manufactured by Texas Instruments. It features 16-bit bidirectional data transmission with three-state outputs in a 56-pin TSSOP package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input levels with CMOS output levels. It includes independent direction control and a select input for multiplexed transmission of registered or real-time data. The component functions as a non-inverting logic circuit with two internal circuits, each handling eight bits.

Feature Summary

• Provides 16-bit bidirectional data transfer capability with registered storage functionality
• Features three-state outputs allowing direct connection to system buses without additional drivers
• Includes independent direction control and a select input for multiplexing registered versus real-time data transmission

Applications

• High-speed data bus interfaces requiring registered buffering
• Multiplexed data transmission systems utilizing real-time or registered data paths
• Bidirectional bus architectures needing controlled data flow direction

Procurement Notes

Verify the specific suffix TPVC against official Texas Instruments documentation to confirm the exact tape and reel quantity and packaging configuration. Ensure the order matches the required operating temperature range and package variant. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and compliance with RoHS directives before finalizing procurement.

Selection Notes

Select this component when designing systems requiring 16-bit registered bus transceivers with independent direction control. It is suitable for applications needing multiplexed transmission options between registered and real-time data. Verify that the 4.75 V to 5.25 V supply voltage range aligns with the system power rails. Confirm that the TSSOP-56 package dimensions fit the PCB layout constraints and thermal requirements.

Part Context

This device belongs to the 74FCT series of high-speed CMOS logic components from Texas Instruments. It is functionally related to other registered bus transceivers like the SN74ABT16646 and 74ACT16646, though electrical characteristics and speed may vary. The FCT series is designed for fast switching speeds compatible with standard logic families while offering improved performance over older technologies.
