CD74HC175MT

Overview

The CD74HC175MT is a high-speed CMOS logic quad D-type flip-flop with reset, manufactured by Texas Instruments. It features four independent D-type flip-flops in a single package, providing parallel data storage capabilities. The device operates within a supply voltage range of 2 V to 6 V and supports clock frequencies up to 20 MHz at nominal supply voltages. It utilizes silicon gate CMOS technology for low power consumption while maintaining speeds comparable to LS TTL devices. The component is housed in a 16-pin SOIC surface-mount package and is rated for an operating temperature range from -55°C to 125°C.

Feature Summary

• Contains four independent D-type flip-flops with separate data inputs and outputs
• Features asynchronous active-low reset functionality for all flip-flops
• Supports edge-triggered data transfer on the positive clock transition
• Offers high noise immunity and low power dissipation typical of CMOS technology

Applications

• Parallel-to-serial and serial-to-parallel data conversion circuits
• Digital signal processing systems requiring temporary data storage
• State machines and control logic in industrial automation
• Memory buffer applications in communication interfaces

Procurement Notes

Verify the specific suffix 'MT' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the ordered part matches the required operating temperature range and voltage specifications for your application environment. Cross-reference the ordering information with the latest Texas Instruments documentation to avoid discrepancies in package dimensions or pinout assignments.

Selection Notes

Select this component when a compact solution for storing four bits of data is required in space-constrained designs. It is suitable for applications needing fast switching speeds with low power consumption. Consider the SOIC package size and lead pitch during PCB layout planning. Verify compatibility with system voltage levels and ensure adequate decoupling capacitors are placed near the power pins to maintain signal integrity.

Part Context

This device belongs to the Texas Instruments HC/UH logic family, known for wide voltage operation and high speed. The CD74HC175 series provides a standard interface for digital logic designers implementing sequential circuits. It serves as a fundamental building block for more complex digital systems, offering reliable performance across a broad temperature range suitable for commercial and industrial environments.

Replacement Considerations

Compatible substitutes include SN74HC175 variants and other quad D-type flip-flops from the same logic family. Ensure replacement parts match the pinout, voltage range, and package type. Verify that alternative components meet the same timing requirements and electrical characteristics specified in the original design.
