74HCT173N,652

Overview

The NXP 74HCT173N,652 is a 4-bit D-type flip-flop with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V and features low power consumption typical of HCT logic. The device is housed in a 16-pin PDIP package and supports synchronous data storage with independent clock inputs for each stage.

Feature Summary

• Provides four independent D-type flip-flops with separate clock inputs
• Features 3-state outputs controlled by an output enable input
• Includes asynchronous master reset functionality

Applications

• Data storage registers in digital systems
• Shift register configurations
• Timing control circuits

Procurement Notes

Verify the manufacturer designation as Nexperia B.V., which succeeded the NXP Standard Product business in February 2017. Confirm the specific suffix 652 corresponds to the PDIP-16 bulk packaging format. Ensure compatibility with standard 5V logic levels required for HCT series operation.

Selection Notes

Select this component when designing circuits requiring multiple synchronized storage elements with tri-state bus interfacing capabilities. The HCT series ensures compatibility with standard TTL logic families while offering improved noise margins compared to older LS variants.

Part Context

This part belongs to the 74HCT family of high-speed CMOS logic devices. It serves as a fundamental building block for sequential logic design, providing reliable data retention and transfer functions in microprocessor-based systems and industrial control applications.

Replacement Considerations

Compatible substitutes include the SN74HCT173 from Texas Instruments or the MC74HCT173A from ON Semiconductor. Verify pinout compatibility and electrical specifications match before implementation.
