CD74HCT174M

Overview

The CD74HCT174M is a high-speed CMOS hex D-type flip-flop manufactured by Harris Corporation. It features buffered positive edge-triggered clock inputs and an asynchronous common reset. The device operates within a supply voltage range of 2V to 6V for HC types, while HCT variants ensure direct LSTTL input logic compatibility with VIL max 0.8V and VIH min 2V. It contains one element with six-bit storage capacity, housed in a 16-pin SOIC package.

Feature Summary

• Buffered positive edge-triggered clock mechanism
• Asynchronous common reset functionality
• Direct LSTTL input logic compatibility

Applications

• Parallel data storage registers
• Shift register configurations
• Timing control circuits

Procurement Notes

Verify the specific manufacturer source, as Harris Semiconductor assets were acquired by Texas Instruments. Confirm RoHS compliance status, as older Harris production may not meet current environmental standards. Ensure the package type matches the required PCB footprint and that the operating temperature range aligns with system requirements.

Selection Notes

Select this component when a hex D-type flip-flop with asynchronous reset is required. The HCT series is suitable for systems interfacing with LSTTL logic levels due to its input compatibility. Consider the 16-pin SOIC package for surface-mount assembly needs. Verify power supply constraints against the specified operating voltage range.
