CD74HCT175MG4

Overview

The CD74HCT175MG4 is a quad D-type flip-flop manufactured by Texas Instruments using silicon-gate CMOS technology. It operates within a supply voltage range of 4.5V to 5.5V and features inputs compatible with 74LSTTL logic levels. The device includes four independent D-type flip-flops, each capable of positive-edge triggering, and provides both true and complement outputs. It supports clock frequencies up to 25 MHz and functions reliably across an extended temperature range from -55°C to 125°C.

Feature Summary

• Provides four independent positive-edge triggered D-type flip-flops with complementary outputs
• Ensures compatibility with 74LSTTL logic families through specific input threshold characteristics
• Utilizes silicon-gate CMOS technology for standard low-power operation

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations
• General-purpose digital storage applications

Procurement Notes

Verify the package type matches the required design constraints, as this component is available in surface-mount formats such as SOIC. Confirm that the selected variant meets the necessary operating temperature specifications for the intended environment. Ensure that the ordering suffix corresponds to the correct packaging configuration required for assembly processes.

Selection Notes

Select this component when a compact solution for storing four bits of data is required alongside LSTTL interface compatibility. The wide operating temperature range makes it suitable for industrial environments. Consider the pin count and package dimensions during layout planning to ensure adequate spacing for thermal management and signal integrity.

Part Context

This part belongs to the Texas Instruments 74HCT series, which bridges the performance gap between standard CMOS and Low-power Schottky TTL. The HCT designation indicates high-speed CMOS technology optimized for direct interfacing with LSTTL systems without requiring level shifting or buffering components.
