74LVC1G34W5-7

Overview

The 74LVC1G34W5-7 is a single buffer gate from the LVC logic family, manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 5.5V and features inputs tolerant to 5.5V for mixed-voltage environments. The device includes IOFF circuitry to support partial power-down applications by disabling outputs and preventing backflow current. It utilizes a standard push-pull output configuration and is housed in an SOT25 package.

Feature Summary

• Supports partial power-down mode operation via integrated IOFF circuitry
• Provides direct interface capability with TTL levels
• Features wide supply voltage range from 1.65V to 5.5V
• Includes overvoltage tolerant inputs accepting up to 5.5V

Applications

• Voltage level shifting between different logic families
• General purpose logic buffering
• Power down signal isolation

Procurement Notes

Verify that the specific part number suffix matches the required package type, as the W5 designation corresponds to the SOT25 form factor. Confirm compliance requirements such as RoHS and halogen-free status directly with the manufacturer or authorized distributors. Ensure the ordering quantity aligns with the standard tape and reel packaging specifications provided in the official documentation.

Selection Notes

Select this component when a single-channel non-inverting buffer is required for low-voltage CMOS applications. The device is suitable for designs needing tolerance to higher input voltages while operating at lower supply rails. Consider the thermal resistance characteristics of the SOT25 package if high ambient temperatures are expected in the final application environment.

Part Context

This component belongs to the 74LVC series of single-gate logic devices produced by Diodes Incorporated. The series offers various package options including DFN and SOT types. The 74LVC1G34 specifically functions as a buffer, providing signal integrity improvements in digital circuits without altering the logical state of the input signal.

Replacement Considerations

Check for automotive-compliant variants like the 74LVC1G34Q if AEC-Q100 qualification is required. Other packages in the same logic family, such as those in X2-DFN or SOT553 formats, may serve as physical alternatives if pin compatibility allows.
