CD74FCT16652CTSM

Overview

The CD74FCT16652CTSM is a registered bus transceiver from the FCT series, manufactured by Harris Corporation. It features two independent functions, each handling eight bits of data with true output polarity. The device utilizes CMOS technology and is housed in a 56-pin Small Outline package (SSOP). It operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal voltage of 5.0 V. The component supports bidirectional data transmission with direction control and includes bus hold inputs to eliminate external pull-up resistors. It is rated for operation between -40 °C and 85 °C.

Feature Summary

• Registered bus transceiver architecture supporting multiplexed transmission of registered or real-time data
• Independent direction control for bidirectional data flow across two 8-bit channels
• Bus hold inputs integrated to maintain signal integrity without requiring external pull-up components

Applications

• Multiplexed data transmission systems requiring registered buffering
• Bidirectional bus interfaces in industrial control environments
• Digital signal processing controller interconnects

Procurement Notes

Verify the manufacturer designation as Harris Corporation, noting that corporate assets were acquired by Texas Instruments. Confirm the specific suffix CTSM corresponds to the 56-SSOP package variant. Ensure compatibility with existing board layouts for PDSO56/SSOP footprints. Check for RoHS compliance status if required by local regulations, as older Harris parts may not meet current standards.

Selection Notes

Select this component when a registered transceiver with independent direction control is required for 8-bit wide buses. The FCT series offers high-speed performance suitable for CMOS logic families. Consider the 56-pin SSOP package constraints for PCB space. Verify that the 3-state outputs with series resistors match the load requirements of the destination devices.

Part Context

This part belongs to the Harris FCT logic family, designed for high-speed CMOS applications. Harris Corporation's semiconductor division was later acquired by Texas Instruments, which continues to support many legacy part numbers. The CD74 prefix indicates a standard logic function variant within the broader catalog.

Replacement Considerations

Check for direct equivalents such as the CD74FCT162652CTMT96, which shares similar registered transceiver characteristics. Verify pinout compatibility before substitution. Note that some variants may differ in package type or temperature rating.
