CD74ACT174M96

Overview

The CD74ACT174M96 is a hex D-type flip-flop manufactured by Harris Corporation, belonging to the ACT series of high-speed CMOS logic. It features six independent positive-edge-triggered D-type flip-flops with asynchronous reset inputs, housed in a 16-pin plastic small outline package (PDSO-16). The device operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 80MHz. It is designed for synchronous operation with true outputs and includes a load capacitance specification of 50pF. The component functions reliably across an extended industrial temperature range from -55°C to 125°C, ensuring stable performance in demanding electronic applications.

Feature Summary

• Contains six independent D-type flip-flops with positive-edge triggering
• Features asynchronous reset inputs for immediate state control
• Utilizes high-speed ACT CMOS technology for enhanced performance
• Provides true outputs with push-pull drive capability

Applications

• Synchronous data storage and register files
• Shift register configurations for serial-to-parallel conversion
• State machine implementations in digital control systems
• Timing delay circuits and pulse synchronization

Procurement Notes

Verify manufacturer authenticity as Harris Corporation assets were acquired by Texas Instruments. Confirm RoHS compliance status, as original Harris versions may differ from current TI equivalents. Check for suffix variations indicating packaging or environmental compliance. Ensure sourcing channels provide valid traceability documentation matching the specific lot codes and manufacturing dates required for your application.

Selection Notes

Select this component when requiring multiple independent D-type flip-flops in a single package. The ACT series offers superior speed compared to standard HC or HCT logic families. Consider the 16-pin SOIC footprint for board space constraints. Verify that the asynchronous reset functionality aligns with system initialization requirements. Ensure operating voltage matches the 4.5V to 5.5V specification for proper logic level compatibility.

Part Context

This part belongs to the 74ACT logic family, representing high-speed CMOS technology derived from the earlier 74HCT series but optimized for faster switching speeds. The CD74 prefix indicates commercial grade temperature rating. As a legacy Harris product, it shares functional pinouts with other 74ACT hex flip-flops like the CD74ACT74, though specific internal circuitry may vary. It serves as a fundamental building block for sequential logic design in microprocessor-based systems.

Replacement Considerations

Texas Instruments CD74ACT174M96E4 serves as a direct equivalent successor. Verify pinout compatibility before substitution. Check updated datasheets for any changes in electrical characteristics or recommended operating conditions introduced during the transition from Harris to Texas Instruments production.
