74HC174PW,112

Overview

The Nexperia 74HC174PW,112 is a hex D-type flip-flop featuring an asynchronous reset. It operates within a supply voltage range of 2V to 6V and utilizes a 16-TSSOP surface-mount package. The device provides non-inverting outputs with specified high-level output current of -5.2mA and low-level output current of 5.2mA. Maximum propagation delay is rated at 27ns under 6V supply with 50pF load. It supports a maximum clock frequency of 50MHz and includes a master reset function for reliable state initialization.

Feature Summary

• Hex D-type edge-triggered flip-flop architecture
• Asynchronous active-low master reset input
• Three-state non-inverting outputs
• Schmitt-trigger action on clock input

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations
• Digital storage and buffering applications
• Timing control logic systems

Procurement Notes

This component is officially designated as obsolete by the manufacturer. Production has ceased, and the product lifecycle status indicates end-of-life. Distributors may offer remaining stock or limited availability, but new manufacturing orders are not accepted. Verify part authenticity carefully due to potential surplus market circulation. Consider immediate design migration to alternative components for long-term supply chain stability.

Selection Notes

Select this component only for legacy system maintenance or specific replacement scenarios where form-factor compatibility is critical. Evaluate performance requirements against available alternatives, as newer generations may offer improved speed or lower power consumption. Ensure that the 16-TSSOP package dimensions match existing PCB footprints. Confirm that the asynchronous reset polarity aligns with system logic requirements before integration.

Part Context

The 74HC174 series belongs to Nexperia's standard 74HC CMOS logic family, designed for general-purpose digital applications. This specific variant integrates six independent D-type flip-flops into a single package, providing compact storage solutions. The PW suffix denotes the TSSOP package type, while the 112 code typically refers to the specific tape-and-reel packaging configuration used for automated assembly processes.

Replacement Considerations

Public confirmed substitutes include SN74HC174PWT (Texas Instruments) and 74HC174PW,118 (Nexperia). These alternatives offer parameter-equivalent functionality and compatible pinouts for direct board replacement in existing designs.
