CD74FCT162543TSM

Overview

The CD74FCT162543TSM is a bus transceiver manufactured by Harris Corporation, belonging to the FCT series. It features two independent non-inverting elements, each handling eight bits of data. The device utilizes CMOS technology and provides three-state outputs for effective bus management. It operates within a supply voltage range of 4.5V to 5.5V, with a nominal rating of 5V. The component is housed in a 56-pin SSOP package and supports bidirectional data flow between ports.

Feature Summary

• Non-inverting bus transceiver architecture with independent control of two eight-bit elements
• Three-state output capability allowing safe connection to shared system buses
• CMOS construction ensuring compatibility with standard logic families

Applications

• High-speed data transmission on computer system buses
• Memory interface buffering and driving
• Bidirectional data routing in embedded systems

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities when sourcing this component. Confirm the specific package type matches the 56-SSOP form factor required for your design. Ensure the voltage specifications align with your system's power rails. Check for any obsolescence notices from the original manufacturer or current distributors before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring high-speed, non-inverting bidirectional data transfer. The FCT series offers faster switching speeds compared to standard HC/HCT logic. Consider the 56-pin SSOP package constraints regarding PCB space and thermal dissipation. Ensure the load capacitance requirements of the driven lines are within the device's specified limits for optimal signal integrity.

Part Context

This part belongs to the Harris FCT (Fast CMOS Technology) family, designed for high-performance digital applications. The FCT series bridges the speed gap between older TTL-compatible logic and advanced CMOS technologies. Harris Corporation was a significant producer of such logic ICs before industry consolidations. This specific model represents an 8-bit wide transceiver configuration common in parallel data paths.
