74LVC74AD/AUJ

Overview

The 74LVC74AD/AUJ is a dual D-type flip-flop with set and reset inputs manufactured by Nexperia. It operates within a supply voltage range of 1.65 V to 3.6 V and features a propagation delay of 8 ns at 3.3 V. The device supports a maximum output current of 50 mA and dissipates up to 500 mW. It functions reliably across an extended temperature range from -40 °C to +125 °C. The component is housed in a 14-TSSOP package, providing surface-mount compatibility for compact circuit designs.

Feature Summary

• Dual D-type flip-flops with dedicated set and reset control inputs
• Wide operating voltage range supporting low-power applications
• High noise immunity and stable switching performance

Applications

• Data storage and register circuits
• Shift registers and counters
• Timing and synchronization logic

Procurement Notes

Verify the specific suffix AUJ against official Nexperia documentation to confirm pinout and packaging details. Confirm RoHS compliance status through the manufacturer's product compliance database. Check for obsolescence notices or lifecycle changes directly from Nexperia before procurement planning.

Selection Notes

Select this component when dual independent D-flip-flops are required in a small surface-mount footprint. Ensure the design voltage falls within the 1.65 V to 3.6 V range. Verify that the TSSOP-14 package dimensions fit the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the 74LVC family of high-speed CMOS logic devices. It provides standard digital logic functionality with improved speed and lower power consumption compared to older TTL equivalents. The device is designed for general-purpose digital applications requiring reliable state retention.

Replacement Considerations

Check Nexperia's official cross-reference list for direct replacements. Verify pin compatibility and electrical specifications if substituting with similar parts from other manufacturers.
