74HC73PW,112

Overview

The 74HC73PW,112 is a dual positive-edge triggered D-type flip-flop manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 6.0 V and features individual D inputs, clock (CP) inputs, and complementary Q outputs. The device includes an asynchronous set input (S_D) that is active LOW. It is housed in a TSSOP-14 package and complies with JEDEC standards for ESD protection and latch-up performance.

Feature Summary

• Dual positive-edge triggered D-type flip-flops with independent data and clock inputs
• Asynchronous active LOW set input for immediate state initialization
• Complementary Q and nQ outputs for flexible logic interfacing
• High noise immunity and robust ESD protection capabilities

Applications

• Data storage and register applications in digital systems
• Shift registers and counter circuits
• Interface between microprocessors and peripheral devices
• State machine implementation in control logic

Procurement Notes

Verify the specific ordering code 74HC73PW,112 against official Nexperia documentation to ensure correct package type and tape/reel specifications. Confirm availability through authorized distributors as stock levels fluctuate. Check for any recent product change notifications regarding marking or packaging updates before finalizing procurement orders.

Selection Notes

Select this component when dual positive-edge triggered D-flip-flops are required with asynchronous set functionality. Ensure the operating voltage range aligns with the system's power supply. Consider the TSSOP-14 package constraints for PCB layout. Verify that the input signal levels match the CMOS logic family requirements for reliable operation.

Part Context

This part belongs to the Nexperia 74HC series of high-speed CMOS logic devices. It is functionally compatible with other industry-standard 74HC73 variants but may differ in packaging or specific electrical characteristics defined by Nexperia. It serves as a fundamental building block for sequential logic circuits requiring precise timing control via positive clock edges.

Replacement Considerations

Direct substitutes include other manufacturers' 74HC73 equivalents such as SN74HC73 from Texas Instruments or MC74HC73 from ON Semiconductor. Verify pinout compatibility and electrical parameter alignment before substitution. Cross-reference with Nexperia's official replacement guide for qualified alternatives.
