74LVC1G34FX4-7

Overview

The Diodes Incorporated 74LVC1G34FX4-7 is a single buffer gate featuring a standard push-pull output, designed for operation within a power supply range of 1.65V to 5.5V. It utilizes the FX4 package code, corresponding to the X2-DFN1409-6 chip-scale alternative form factor. The device inputs are tolerant to 5.5V, enabling compatibility in mixed-voltage environments. It includes IOFF circuitry that disables the output to prevent damaging current backflow during partial power-down applications. The component supports direct interface with TTL levels and offers ESD protection exceeding 2000-V Human Body Model and 1000-V Charged Device Model ratings.

Feature Summary

• Single buffer gate with standard push-pull output configuration
• IOFF circuitry enables safe partial-power-down mode operation by disabling outputs
• Inputs accept up to 5.5V for mixed-voltage environment compatibility
• Totally lead-free and fully RoHS compliant

Applications

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

Procurement Notes

Verify the FX4 suffix corresponds to the X2-DFN1409-6 package when sourcing. Confirm the -7 suffix indicates tape and reel packaging. Ensure the specific revision of the datasheet matches the production batch requirements. Check for automotive compliance needs, as this part differs from the qualified 74LVC1G34Q variant. Validate pinout alignment with the X2-DFN1409-6 footprint before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a single non-inverting buffer in compact spaces due to its chip-scale package. It is suitable for systems operating between 1.65V and 5.5V where input tolerance up to 5.5V is necessary. Consider the IOFF feature if the design involves partial power-down states to protect downstream components. Ensure the thermal resistance characteristics of the X2-DFN1409-6 package meet the system's thermal management requirements.

Part Context

This part belongs to the 74LVC1G series of low-voltage CMOS logic devices manufactured by Diodes Incorporated. The 74LVC1G34 specifically denotes a single buffer gate. The FX4 ordering suffix identifies the physical package as X2-DFN1409-6, distinguishing it from other available packages like SOT25 or DFN0808. This series is engineered for portable electronics and general-purpose digital applications requiring low power consumption and wide voltage flexibility.

Replacement Considerations

The 74LVC1G34Q is an automotive-compliant alternative available under a separate datasheet. Other package variants such as 74LVC1G34W5-7 (SOT25) or 74LVC1G34FS3-7 (X2-DFN0808-4) offer identical electrical functionality but require different PCB footprints. Verify package dimensions and pin assignments when substituting.
