CD74HC175E

Overview

The CD74HC175E is a high-speed CMOS logic quad D-type flip-flop manufactured by Texas Instruments. It features four independent D-type flip-flops with a common asynchronous reset input, housed in a 16-pin SOIC package. The device operates within a supply voltage range of 2V to 6V and supports clock frequencies up to 20 MHz at nominal supply conditions. Designed for robust performance, it functions across an extended temperature range from -55°C to +125°C, ensuring reliability in demanding industrial environments.

Feature Summary

• Integrates four independent D-type flip-flops with a shared asynchronous reset mechanism for synchronized data clearing.

Applications

• General-purpose digital data storage circuits
• Shift register configurations for serial-to-parallel conversion
• State machine implementation in control systems

Procurement Notes

Verify the specific suffix 'E' confirms the SOIC-16 surface-mount package variant. Confirm RoHS compliance status as manufacturing processes may evolve. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target application design.

Selection Notes

Select this component when a compact surface-mount solution for multi-bit storage is required. The HC series offers standard CMOS speed suitable for general logic applications. Verify that the operating voltage range aligns with the system power rails and that the package footprint fits the PCB layout constraints.

Part Context

This component belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. The 74HC175 specifically provides quad D-type flip-flop functionality. It serves as a fundamental building block for sequential logic designs requiring multiple storage elements within a single integrated circuit package.

Replacement Considerations

• CD74HC175M (SOIC-16 variant)
• SN74HC175N (PDIP-16 through-hole variant)
