74LVC74ABQ-Q100X

Overview

The Nexperia 74LVC74ABQ-Q100X is a dual D-type flip-flop with set and reset, positive-edge trigger. It operates within a supply voltage range of 1.2 V to 3.6 V. The device features Schmitt-trigger inputs for noise tolerance and includes I_OFF circuitry for partial power-down applications. It is qualified to AEC-Q100 Grade 1 standards for automotive use. The component is housed in a DHVQFN-14 package (SOT762) and supports surface mount installation.

Feature Summary

• Dual edge-triggered D-type flip-flops with individual asynchronous active LOW set and reset inputs
• Schmitt-trigger action at all inputs provides high tolerance for slower input rise and fall times
• I_OFF circuitry disables outputs during partial power-down to prevent damaging backflow current

Applications

• Automotive electronic systems requiring AEC-Q100 Grade 1 qualification
• Mixed 3.3 V and 5 V logic environments utilizing 5 V tolerant inputs
• Digital data storage and sequential logic circuits

Procurement Notes

Verify the specific suffix 'X' indicates the tape and reel packaging configuration as documented by the manufacturer. Confirm that the DHVQFN-14 package matches the target PCB footprint requirements. Ensure the AEC-Q100 Grade 1 qualification aligns with the intended automotive application temperature ranges. Cross-reference the 12NC code for accurate ordering specifications.

Selection Notes

Select this component when dual independent D-type flip-flops are required in a compact surface-mount package. The wide supply voltage range allows flexibility in low-voltage designs. The inclusion of asynchronous set and reset functions provides immediate control over output states without clock dependency. Verify compatibility with system voltage levels given the 5 V tolerant input capability.

Part Context

This part belongs to the Nexperia 74LVC family, designed for low-voltage CMOS applications. The LVC series offers direct interface capabilities with TTL levels while maintaining low power consumption. The ABQ suffix denotes the specific DHVQFN package variant, ensuring compatibility with modern miniaturized PCB layouts.

FAQ

How does the I_OFF circuitry function in this device?

The I_OFF circuitry disables the outputs when the device is in a partial power-down state, preventing damaging backflow current through the component.

What is the trigger mechanism for the data transfer?

Information on the data input is transferred to the Q output on the LOW-to-HIGH transition of the clock pulse, indicating a positive-edge trigger.
