CD74HCT175MT

Overview

The CD74HCT175MT is a high-speed CMOS quad D-type flip-flop manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features positive-edge triggering with an asynchronous clear input. The device utilizes silicon gate CMOS technology, ensuring low power consumption while maintaining speeds comparable to LSTTL logic families. It is housed in a 16-pin SOIC surface-mount package and supports operation across an extended temperature range from -55°C to 125°C.

Feature Summary

• Provides four independent D-type flip-flops with complementary outputs for versatile digital storage applications.
• Features positive-edge clock triggering to synchronize data capture accurately.
• Includes an asynchronous clear input to reset all flip-flops independently of the clock signal.
• Ensures compatibility with standard TTL logic levels through HCT series input specifications.

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data transmission
• General-purpose memory storage elements in digital systems

Procurement Notes

Verify the specific suffix 'MT' against official datasheets to confirm the tape-and-reel packaging format and exact pinout configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a compact surface-mount solution for quadruple D-type storage is required. It is suitable for designs needing LSTTL-compatible inputs with CMOS low-power advantages. Consider the 16-SOIC package constraints and thermal performance characteristics relative to your PCB layout and operating environment requirements.

Part Context

This part belongs to the Texas Instruments 74HCT series, which bridges the gap between standard CMOS and Low-power Schottky TTL technologies. The series is designed to offer the noise immunity of CMOS with the drive capability and speed of TTL, making it widely used in mixed-logic environments requiring reliable interfacing between different logic families.

Replacement Considerations

Check for equivalents such as the CD74HCT175M or CD74HCT175E depending on the required package type (SOIC vs DIP). Verify that any substitute maintains the same HCT logic family characteristics and pinout compatibility to ensure seamless integration without circuit redesign.
