74LVC1G34QW5-7

Overview

The 74LVC1G34QW5-7 is an automotive-compliant single buffer gate manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 5.5V and features inputs tolerant to 5.5V regardless of the VCC level. The device utilizes standard push-pull outputs and includes I_OFF circuitry for partial power-down applications. It supports Grade 1 ambient temperature operation from -40°C to +125°C and meets AEC-Q100 standards for ESD protection, exceeding 2000V HBM and 1000V CDM ratings.

Feature Summary

• AEC-Q100 qualified with PPAP capability for automotive applications
• I_OFF circuitry enables safe partial power-down mode operation
• Inputs accept up to 5.5V independent of VCC level
• Standard push-pull output configuration

Applications

• Voltage Level Shifting
• General Purpose Logic
• Power Down Signal Isolation
• Automotive Applications within Grade 1 Temperature Range
• Industrial Computing/Controls/Automation

Procurement Notes

Verify that the specific part number suffix matches the required package type, as the Q series is available in both SOT25 and SOT353 configurations. Confirm compliance requirements such as RoHS and halogen-free status directly with the manufacturer documentation. Ensure the application environment aligns with the specified Grade 1 temperature range and electrical characteristics before finalizing procurement.

Selection Notes

Select this component when an automotive-grade buffer is required for mixed-voltage environments. The wide input tolerance allows interfacing between different logic levels without external components. Consider the SOT25 package for this specific model number. Verify that the operating temperature range and ESD protection levels meet the system's reliability standards.

Part Context

This component belongs to the 74LVC1G34Q family of single buffer gates designed for automotive use. It shares functional similarities with other LVC series buffers but is distinguished by its AEC-Q100 qualification and specific packaging options like SOT25. The Q suffix indicates automotive compliance, differentiating it from standard commercial variants.

Replacement Considerations

Check datasheets for alternative single buffer gates with matching voltage ranges and AEC-Q100 qualifications. Verify pin compatibility and package dimensions if substituting with non-equivalent packages.
