CD74HCT74M96

Overview

The CD74HCT74M96 is a dual D-type flip-flop manufactured by Harris Corporation, belonging to the HCT logic series. It features positive edge triggering and complementary outputs. The device operates within a temperature range of -55°C to 125°C and supports a maximum frequency of 20 MHz. Packaged in a 14-pin SOIC format, it integrates set and reset functions for synchronous data storage applications.

Feature Summary

• Dual D-type flip-flop configuration with independent set and reset controls
• Positive edge-triggered operation ensuring precise timing synchronization
• Complementary output structure providing both true and inverted signals

Applications

• Synchronous digital data storage circuits
• Shift register implementations requiring dual elements
• Timing control systems utilizing preset and clear functions

Procurement Notes

Verify manufacturer origin as Harris Corporation or Texas Instruments due to historical acquisition. Confirm package type matches 14-SOIC specifications. Check RoHS compliance status as original Harris versions may not meet current standards. Validate part marking against official datasheet references to ensure authenticity.

Selection Notes

Select this component when dual D-type functionality with separate set and reset inputs is required. Ensure compatibility with HCT logic voltage levels for system integration. Consider the 125°C operating temperature range for high-thermal environments. Verify pinout alignment with existing PCB layouts before implementation.

Part Context

This component belongs to the 74HCT family of CMOS logic devices, designed for compatibility with TTL inputs while offering CMOS performance. The CD74HCT74 variant specifically provides two independent D-type flip-flops in a single package, widely used in sequential logic design.

Replacement Considerations

CD74HCT74M96.A is a documented substitute variant from Texas Instruments. Verify pin compatibility and electrical characteristics match before substitution. Original Harris units are obsolete; TI sources are the primary alternative.
