CD74FCT16543CTSM

Overview

The CD74FCT16543CTSM is a high-speed CMOS transceiver manufactured by Harris Corporation. It features two non-inverting elements, each handling eight bits of data. The device utilizes a 56-pin SSOP package and operates with a supply voltage range of 4.5V to 5.5V. It supports three-state outputs for effective bus driving applications.

Feature Summary

• Non-inverting bidirectional data transfer capability
• Three-state output configuration for bus isolation
• High-speed CMOS technology implementation

Applications

• Bidirectional bus-oriented transmissions
• Memory-to-memory data transfers
• Register-to-register communication links

Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successors, noting that original Harris components may be obsolete. Confirm the specific 56-SSOP package type and electrical ratings match system requirements. Check RoHS compliance status, as original Harris parts often lack modern environmental certifications. Ensure the part number suffix accurately reflects the tape-and-reel or bulk packaging variant required for assembly.

Selection Notes

Select this component when designing systems requiring reliable bidirectional data flow between registers or memory blocks. The non-inverting nature simplifies logic design compared to inverting alternatives. Verify that the 4.5V to 5.5V operating voltage aligns with the target system's power rails. Consider the 56-pin SSOP footprint constraints during PCB layout planning.

Part Context

This device belongs to the FCT (Fast CMOS Technology) series, designed for high-performance digital applications. It serves as a critical interface component in complex digital systems, facilitating efficient data movement across multiple circuit nodes while maintaining signal integrity through its specialized output structure.

Replacement Considerations

Consult official Harris Corporation documentation for direct cross-reference equivalents. Verify pin compatibility and electrical specifications before substituting with other FCT series transceivers or generic CMOS alternatives.
