74HCT74PW,112

Overview

The Nexperia 74HCT74PW,112 is a dual positive-edge triggered D-type flip-flop with set and reset inputs, housed in a 16-TSSOP surface-mount package. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features asynchronous active-low set and reset functions that operate independently of the clock input. It includes Schmitt-trigger action on the clock input for tolerance to slow rise and fall times. The component supports ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Dual positive-edge triggered D-type flip-flops with complementary outputs.
• Asynchronous active-low set and reset inputs independent of clock.
• Schmitt-trigger clock input for improved noise immunity.
• High electrostatic discharge protection capabilities.

Applications

• Parallel-to-serial data conversion circuits.
• Shift register construction.
• General-purpose storage elements in digital logic systems.
• Timing and synchronization applications.

Procurement Notes

Verify current availability status as distribution channels may vary. Confirm RoHS compliance and specific packaging requirements such as tape and reel or cut tape upon order placement. Ensure compatibility with existing design specifications regarding voltage levels and package dimensions before finalizing procurement decisions.

Selection Notes

Select this component when dual D-type flip-flops with set and reset functionality are required in a compact surface-mount format. The HCT series ensures TTL-compatible input levels while maintaining CMOS output drive characteristics. Consider the 16-TSSOP package for space-constrained PCB layouts requiring high pin density.

Part Context

This part belongs to the Nexperia 74HCT family of high-speed CMOS logic devices. It provides standard dual D-flip-flop functionality compatible with TTL logic levels. The PW suffix indicates the TSSOP package type, suitable for automated surface-mount assembly processes in consumer and industrial electronics manufacturing.

Replacement Considerations

Consider equivalent parts from other manufacturers offering dual D-flip-flops in 16-TSSOP packages with HCT logic levels. Verify pinout compatibility and electrical parameter alignment before substitution to ensure circuit integrity without redesign.

FAQ
