74LVC1G34FW4-7

Overview

The 74LVC1G34FW4-7 is a single non-inverting buffer gate manufactured by Diodes Incorporated, designed for operation within a power supply range of 1.65V to 5.5V. It features a standard push-pull output and inputs tolerant to 5.5V, facilitating mixed-voltage environments. The device incorporates IOFF circuitry to disable the output during partial power-down applications, preventing damaging current backflow. It operates across an extended temperature range from -40°C to +125°C.

Feature Summary

• Supports partial-power-down mode operation via integrated IOFF circuitry that disables outputs to prevent backflow currents.
• Features input tolerance up to 5.5V, enabling direct interface with TTL levels in mixed-voltage systems.
• Provides robust ESD protection exceeding 2000-V Human Body Model and 1000-V Charged Device Model standards.

Applications

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

Procurement Notes

Verify the specific package marking code UK corresponds to the X2-DFN1010-6 configuration when inspecting delivered units. Confirm compliance with RoHS 3 and Halogen-free requirements as defined by the manufacturer's green product definitions. Ensure design accounts for the specified thermal resistance values associated with the DFN footprint.

Selection Notes

Select this component for designs requiring a single-channel buffer with high input voltage tolerance. The FW4 suffix indicates the X2-DFN1010-6 package, suitable for space-constrained surface-mount layouts. Consider the propagation delay characteristics relative to the operating voltage when designing for high-speed signal integrity.
