74LVC2G34GXZ

Overview

The Nexperia 74LVC2G34GXZ is a dual buffer gate housed in an X2SON6 (SOT1255-2) package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports inputs driven from 3.3 V or 5 V devices, enabling translation in mixed-voltage environments. The device features Schmitt-trigger action for tolerance to slow input transitions and includes IOFF circuitry for partial power-down mode operation. It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36, and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Schmitt-trigger inputs provide high noise immunity and tolerance for slower rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent potentially damaging backflow currents.
• Direct interface capability with TTL levels allows seamless integration with various logic families.
• Overvoltage tolerant inputs support 5.5 V signals while operating at lower supply voltages.

Applications

• Mixed 3.3 V and 5 V voltage level translation
• Partial power-down applications requiring backflow current prevention
• Signal buffering in CMOS low power dissipation circuits

Procurement Notes

Verify the specific ordering suffix 'XZ' against official Nexperia documentation to confirm the exact tape-and-reel packaging configuration and marking code. Ensure that the selected component meets the required thermal performance specifications for the X2SON6 package, as total power dissipation derates linearly above 75 °C. Confirm compliance with applicable environmental directives such as RoHS before finalizing procurement.

Selection Notes

Select this component when a dual non-inverting buffer with Schmitt-trigger inputs is required for signal integrity in noisy environments. The X2SON6 package is suitable for applications demanding extremely thin profiles and enhanced thermal properties compared to standard XSON packages. Verify that the operating temperature range of -40 °C to +125 °C aligns with the system's environmental constraints.

Part Context

This part belongs to the 74LVC family of logic ICs, designed for low-voltage CMOS applications. The 74LVC2G34 series provides dual buffer functionality across multiple package options, including TSSOP6, SC-74, and various XSON variants. The GXZ designation specifically identifies the X2SON6 package variant, which offers thermal enhancement and a body size of 1.0 x 0.8 mm.

Replacement Considerations

Cross-reference with other 74LVC2G34 package variants such as 74LVC2G34GW or 74LVC2G34GM if pin compatibility and package footprint allow. Ensure that any substitute maintains the same logic function, voltage range, and thermal characteristics. Verify that the replacement part number is explicitly listed as a compatible alternative in official Nexperia documentation.
