CD74FCT162374CTSM

Overview

The CD74FCT162374CTSM is a high-speed CMOS bus driver manufactured by Harris Corporation, belonging to the FCT series. It features two independent functions, each handling eight bits of data with true output polarity. The device utilizes a 48-pin PDSO package and operates within a supply voltage range of 4.5V to 5.5V. Key electrical characteristics include a maximum propagation delay of 5.5 ns and a load capacitance rating of 50 pF. It supports an operating temperature range from -40°C to 85°C and provides three-state outputs with series resistors for improved signal integrity.

Feature Summary

• Features bus hold inputs that eliminate the need for external pull-up resistors
• Provides three-state outputs integrated with series resistors
• Supports low-enable control logic for efficient system management

Applications

• High-speed data bus driving applications
• Memory interface circuits
• Microprocessor-based system interconnects

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix matches the required package type and thermal specifications. Check for RoHS compliance status as indicated in official documentation, since older Harris batches may differ. Ensure storage conditions meet moisture sensitivity level requirements before soldering.

Selection Notes

Select this component when designing systems requiring fast 8-bit bus drivers with inherent input holding capabilities. Compare against standard 74FCT equivalents if lower cost is prioritized over speed. Consider the 48-pin footprint constraints during PCB layout. Evaluate thermal performance if multiple units operate simultaneously in confined spaces.

Part Context

This part belongs to the Harris FCT (Fast CMOS) family, designed to bridge the performance gap between standard TTL and advanced CMOS technologies. It offers faster switching speeds than HC/HCT variants while maintaining CMOS power efficiency. The CD74 prefix indicates commercial grade availability within the broader 74-series logic ecosystem.
