CD74HCT173M96

Overview

The CD74HCT173M96 is a high-speed CMOS quad D-type flip-flop manufactured by Harris Corporation. It features four independent edge-triggered D-type flip-flops with positive-edge triggering and an asynchronous master reset input. The device operates within a supply voltage range of 4.5V to 5.5V and supports clock frequencies up to 60MHz. It utilizes a 16-pin Small Outline Integrated Circuit (SOIC) package, specifically the SOIC-16 form factor, designed for surface-mount applications in digital logic systems.

Feature Summary

• Contains four independent positive-edge triggered D-type flip-flops
• Includes an asynchronous master reset input for immediate clearing of all flip-flops
• Supports high-speed operation with maximum clock frequencies reaching 60MHz
• Compatible with standard 5V CMOS logic families through HCT input specifications

Applications

• High-speed disk and tape controllers
• Communication buffer circuits
• Parallel-to-serial data conversion modules
• General-purpose register storage in digital systems

Procurement Notes

Verify the manufacturer origin carefully, as this component was originally produced by Harris Semiconductor before its acquisition by Texas Instruments. Confirm that the specific M96 suffix corresponds to the intended tape-and-reel packaging configuration. Ensure compatibility with existing 5V logic levels and check for RoHS compliance status relative to current manufacturing standards.

Selection Notes

Select this component when a compact solution for storing four bits of data with synchronous loading and asynchronous reset is required. The HCT series ensures compatibility with standard TTL logic levels while maintaining CMOS low power consumption. Consider the 60MHz speed capability for timing-critical applications requiring fast data latching without external buffering.

Part Context

This part belongs to the widely used 74HCT logic family, originally developed by Harris Semiconductor. The CD74 prefix indicates a commercial grade device. Following Harris's acquisition by National Semiconductor and subsequently Texas Instruments, production continued under TI. The M96 suffix typically denotes specific tape-and-reel packaging options offered by the manufacturer for automated assembly processes.

Replacement Considerations

Texas Instruments CD74HCT173 variants serve as direct replacements. Other manufacturers producing JEDEC-compliant 74HCT173 devices may also be compatible if pinouts and electrical characteristics match.
