74LVC3G34DC-Q100H

Overview

The Nexperia 74LVC3G34DC-Q100H is a triple buffer in an 8-lead VSSOP package (SOT765-1). It operates on a supply voltage range of 1.65 V to 5.5 V with inputs tolerant up to 5.5 V. The device provides ±24 mA output drive at 3.0 V and features Schmitt-trigger action for noise immunity. It includes IOFF circuitry to prevent backflow current during partial power-down states. Qualified to AEC-Q100 Grade 1, it functions reliably from -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• IOFF circuitry prevents damaging backflow current when powered down
• Schmitt-trigger inputs provide tolerance for slow signal transitions
• Wide supply voltage range supporting mixed 3.3 V and 5 V environments

Applications

• Automotive engine control units
• Mixed-signal translation between 3.3 V and 5 V logic levels
• Partial power-down applications requiring backflow prevention

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's ordering information to confirm packaging details. Ensure the design accommodates the VSSOP8 thermal characteristics and derating requirements specified in the datasheet. Confirm that the application environment remains within the recommended operating temperature range of -40 °C to +125 °C for full specification compliance.

Selection Notes

Select this component when automotive reliability is required alongside low-power CMOS operation. The wide input voltage tolerance allows direct interfacing with 5 V devices without level shifters. The inclusion of IOFF functionality makes it suitable for systems where outputs must remain disabled during standby or power-loss conditions to protect downstream circuitry.

Part Context

This part belongs to the 74LVC3G34-Q100 family of triple buffers designed for automotive electronics. It shares functional specifications with other variants in the series but utilizes the VSSOP8 plastic very thin shrink small outline package. The marking code for this specific package version is Y34, distinguishing it from TSSOP8 alternatives.

Replacement Considerations

The 74LVC3G34DP-Q100H serves as a package alternative using the TSSOP8 form factor while maintaining identical electrical performance and automotive qualification.
