74HC173N,652

Overview

The 74HC173N,652 is a high-speed silicon-gate CMOS device manufactured by Nexperia (formerly NXP Standard Products). It functions as a 4-bit D-type flip-flop with separate clock inputs and three-state outputs. The component operates within a voltage range of 2V to 6V for HC types. It features synchronous data loading via dual enable inputs and an asynchronous master reset. The device supports bus driving capabilities and includes ESD protection exceeding 2000V HBM.

Feature Summary

• Synchronous 4-bit D-type flip-flop architecture
• Three-state output control via dual enable logic
• Asynchronous master reset functionality
• Wide operating voltage range supporting 2V to 6V

Applications

• High-speed disk and tape controllers
• Communication buffer applications
• Parallel data storage systems
• Bus-oriented memory register implementations

Procurement Notes

Verify the manufacturer designation carefully, as the former NXP Standard Product business was rebranded to Nexperia. Ensure the ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status through official datasheets or distributor documentation prior to procurement to meet regulatory requirements.

Selection Notes

Select this component when a 4-bit parallel load register with independent clocking and tri-state outputs is required. Consider the 2V-6V operating range for compatibility with various logic families. Evaluate propagation delay specifications against system timing constraints. Verify that the PDIP-16 package aligns with PCB layout and assembly requirements.

Part Context

This part belongs to the 74HC173 series of 4-bit D-type flip-flops. It is produced under the Nexperia brand following the separation from NXP's standard product division. The device complies with JEDEC standard no. 7A and is available in multiple package options including SOIC, TSSOP, and PDIP formats.

Replacement Considerations

Public confirmed substitutes include CD74HC173E and CD74HC173PWR. These parts share identical logical functionality and pinout configurations. Verify electrical parameters and package dimensions before substitution.
