74LV74D/AUJ

Overview

The 74LV74D/AUJ is a dual D-type flip-flop with set and reset functions, manufactured by NXP USA Inc. It operates on a supply voltage range of 1.0V to 5.5V. The device features positive-edge triggering and includes clamp diodes on inputs for ESD protection. It is housed in a 14-SOIC package (SOP14) and supports surface-mount installation. The component complies with JEDEC standard no. 7a and offers an operating temperature range from -40°C to +125°C.

Feature Summary

• Dual D-type flip-flops with dedicated set and reset inputs
• Positive-edge trigger mechanism for data capture
• Wide operating voltage range supporting 1.0V to 5.5V
• Input clamp diodes provide ESD protection capabilities

Applications

• Parallel-to-serial data conversion circuits
• Serial-to-parallel data conversion interfaces
• Shift register configurations for data storage
• General-purpose memory element applications

Procurement Notes

Verify the specific ordering suffix (e.g., AUJ vs. D) against the manufacturer's current catalog to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding marking or assembly changes before finalizing procurement orders.

Selection Notes

Select this component when a dual D-type flip-flop with independent set and reset controls is required. Ensure the system voltage falls within the 1.0V to 5.5V range. Consider the 14-SOIC package dimensions for PCB layout constraints and verify that the positive-edge triggering aligns with the system clock polarity requirements.

Part Context

This part belongs to the 74LV series, designed for low-voltage CMOS applications. It maintains pin and function compatibility with the 74HC/HCT74 family, allowing for potential design upgrades where lower voltage operation is needed while retaining similar interface characteristics.

Replacement Considerations

Public confirmed substitute part numbers include 74LV74D,112 and 74LV74-Q100.
