74AHC74PW/AUJ

Overview

The 74AHC74PW/AUJ is a dual D-type flip-flop with set and reset functions, utilizing positive-edge triggering. It belongs to the NXP AHC logic series, designed for high-speed CMOS applications. The device operates within a supply voltage range of 2 V to 5.5 V and features balanced propagation delays. Inputs accept voltages exceeding VCC, supported by Schmitt-trigger action for noise immunity. ESD protection exceeds specified JEDEC standards. The component is housed in a TSSOP-14 package, suitable for surface-mount technology.

Feature Summary

• Dual D-type flip-flops with independent set and reset controls
• Positive-edge triggering mechanism for data capture
• Schmitt-trigger inputs providing enhanced noise immunity
• ESD protection compliant with JEDEC standard No. 7-A

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations
• Timing delay elements
• Latch-based memory storage interfaces

Procurement Notes

Verify the specific suffix AUJ against official Nexperia or NXP documentation to confirm pinout compatibility and tape/reel specifications. Ensure the source document explicitly lists this variant as an active or discontinued part number. Cross-reference the manufacturer's latest product change notification to confirm material composition and RoHS status prior to procurement.

Selection Notes

Select this component when dual edge-triggered storage with asynchronous control is required in space-constrained designs. The AHC series offers superior speed compared to standard HC logic while maintaining low power consumption. Verify that the input voltage levels match the system's CMOS requirements rather than TTL levels, which would necessitate the AHCT variant.

Part Context

This part is a member of the 74AHC family, representing high-speed silicon-gate CMOS technology. It maintains pin compatibility with legacy Low-Power Schottky TTL (LSTTL) devices, facilitating upgrades in existing systems. The PW/AUJ designation indicates a TSSOP-14 plastic surface-mount package, widely used in consumer electronics and industrial control boards requiring compact form factors.

Replacement Considerations

NXP Semiconductors and Nexperia list 74AHC74PW as a direct equivalent. For automotive applications, consider the 74AHC74PW-Q100 variant if AEC-Q100 qualification is required. Verify package dimensions and thermal characteristics when substituting with other manufacturers' dual D-flip-flops.
