74LVC3G34V8-7

Overview

The 74LVC3G34V8-7 is a triple buffer gate manufactured by Diodes Incorporated, designed for operation with a power supply range of 1.65V to 5.5V. It features standard push-pull outputs and inputs tolerant to 5.5V, enabling use in mixed voltage environments. The device supports partial power down applications via IOFF circuitry, which disables outputs to prevent damaging current backflow. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Supports partial power down mode operation through integrated IOFF circuitry that prevents output current backflow when powered down
• Inputs accept up to 5.5V, allowing compatibility in mixed voltage environments
• Provides ESD protection exceeding 2000V Human Body Model and 1000V Charged Device Model

Applications

• Voltage-level shifting
• General-purpose logic
• Power down signal isolation

Procurement Notes

Verify the specific VSSOP-8 package configuration matches the design requirements. Confirm the ordering suffix indicates the correct tape and reel quantity. Ensure the component meets RoHS compliance standards for the intended market. Validate that the operating voltage range aligns with the system power supply specifications.

Selection Notes

Select this component for applications requiring three independent non-inverting buffers in a compact surface-mount package. Consider its wide supply voltage range and input tolerance for interfacing between different logic families. Evaluate the propagation delay characteristics against the system timing requirements at the target operating voltage.

Part Context
