74LVC1G34Z-7

Overview

The Diodes Incorporated 74LVC1G34Z-7 is a single non-inverting buffer gate in the LVC logic family, housed in an SOT553 package. It operates within a supply voltage range of 1.65V to 5.5V and features standard push-pull outputs with ±24mA drive capability at 3.3V. The device includes IOFF circuitry for partial power-down applications, preventing damaging backflow currents. Inputs are tolerant to 5.5V, enabling direct interface with TTL levels in mixed-voltage environments.

Feature Summary

• IOFF circuitry supports partial-power-down mode operation by disabling the output to prevent current backflow.
• Inputs accept up to 5.5V, allowing compatibility in mixed-voltage systems.
• Provides direct interface capability with TTL logic levels.

Applications

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

Procurement Notes

Verify that the ordering suffix Z corresponds specifically to the SOT553 package configuration. Confirm the -7 suffix indicates tape and reel packaging containing 4,000 units per reel. Ensure compliance with RoHS 3 and halogen-free requirements if specified for the project.

Selection Notes

Select this component when a single-channel non-inverting buffer is required for low-voltage CMOS applications. The SOT553 package offers a compact footprint suitable for space-constrained designs. Verify that the 5.5V input tolerance meets the requirements for interfacing with higher voltage logic signals.

Part Context
