74LVC2G74DC-Q100H

Overview

The Nexperia 74LVC2G74DC-Q100H is an automotive-grade dual D-type flip-flop with positive edge triggering, housed in a VSSOP8 package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports a wide operating temperature range from -40 °C to +125 °C. The device features Schmitt-trigger inputs for noise tolerance, I_OFF circuitry for partial power-down protection, and high ESD capability exceeding 2 kV HBM.

Feature Summary

• Dual D-type flip-flops with positive edge triggering
• Schmitt-trigger inputs for improved noise immunity
• I_OFF circuitry prevents backflow current during power-down
• AEC-Q100 qualified for automotive reliability

Applications

• Automotive electronic control units (ECUs)
• Data storage and shift register circuits
• Timing and synchronization logic
• Signal path buffering in mixed-voltage systems

Procurement Notes

Verify the specific suffix 'H' against the official Nexperia datasheet to confirm it denotes the standard RoHS-compliant variant without halogens or SVHCs exceeding limits. Ensure the ordering part number matches the exact package code SOT765-1 (VSSOP8) and that the component meets AEC-Q100 Grade requirements for your target application environment.

Selection Notes

Select this component when dual independent D-flip-flops are required in space-constrained automotive designs. The VSSOP8 package offers a compact footprint suitable for dense PCB layouts. Consider the I_OFF feature if the system requires safe operation during partial power-down states to prevent bus contention.

Part Context

This part belongs to the Nexperia 74LVC-Q100 family, which provides low-voltage CMOS logic optimized for automotive applications. The series ensures compatibility with standard 3.3 V and 5 V logic levels while maintaining robust performance across extreme temperature ranges defined by automotive standards.

Replacement Considerations

Direct substitutes include other automotive-qualified dual D-flip-flops in VSSOP8 packages such as the SN74LVC2G74-Q1 from Texas Instruments, provided pinout and electrical characteristics match exactly.
