74LVC3G34GF,115

Overview

The Nexperia 74LVC3G34GF,115 is a triple non-inverting buffer within the 74LVC logic family. It operates on a supply voltage range of 1.65 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device includes IOFF circuitry to prevent backflow current during power-down states. It supports direct interfacing with TTL levels and complies with JEDEC standards for various voltage ranges. The component is specified for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Triple buffer configuration with Schmitt-trigger inputs
• IOFF circuitry prevents damaging backflow current when powered down
• Wide supply voltage range supporting mixed 3.3 V and 5 V environments

Applications

• Mixed 3.3 V and 5 V signal translation
• Buffering digital signals in portable devices
• General-purpose buffering in consumer electronics

Procurement Notes

Verify the specific package type associated with the GF suffix against official Nexperia documentation, as it was removed from the standard product data sheet revision history. Confirm availability through authorized distributors and ensure compliance with RoHS and REACH regulations before procurement.

Selection Notes

Select this component for applications requiring triple buffering with high noise immunity due to Schmitt-trigger inputs. Ensure the design accommodates the wide supply voltage range and verify that the operating temperature range meets environmental requirements. Consider the IOFF feature if partial power-down modes are utilized in the system architecture.

Part Context

The 74LVC3G34GF,115 belongs to the 74LVC series of CMOS logic devices. This series is designed for low-voltage applications while maintaining compatibility with higher voltage interfaces. The part number indicates a specific package variant, though detailed package information for the GF suffix requires verification against updated manufacturer records.

Replacement Considerations

Check for alternative packages within the same 74LVC3G34 family, such as DP, DC, GT, GN, or GS variants, which are documented in the datasheet. Verify pinout compatibility and electrical specifications before substituting.
