74LV1T34GXH

Overview

The Nexperia 74LV1T34GXH is a single supply translating buffer housed in an X2SON5 (SOT1226-3) package. It supports a supply voltage range of 1.6 V to 5.5 V and features 5 V tolerant inputs. The device facilitates up translation from 1.2 V to 1.8 V at VCC = 1.8 V, 1.5 V to 2.5 V at VCC = 2.5 V, 1.8 V to 3.3 V at VCC = 3.3 V, and 3.3 V to 5.0 V at VCC = 5.0 V. Down translation capabilities include 3.3 V to 1.8 V at VCC = 1.8 V, 3.3 V to 2.5 V at VCC = 2.5 V, and 5.0 V to 3.3 V at VCC = 3.3 V. Propagation delay ranges from 3.6 ns to 11.4 ns depending on load capacitance and supply voltage.

Feature Summary

• Supports bidirectional level translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V CMOS logic levels using a single supply voltage.
• Features 5 V tolerant input pins that enable safe down translation from higher voltage domains without external components.
• Provides latch-up performance exceeding 250 mA per JESD 78 Class II standards for enhanced reliability.

Applications

• Portable applications
• PC and notebooks
• Industrial controller
• Telecom

Procurement Notes

Verify the specific ordering suffix 'H' corresponds to the reel packaging configuration required for your assembly line. Confirm the X2SON5 package dimensions match your PCB footprint design. Ensure the ambient temperature operating range aligns with your system's thermal environment specifications before finalizing procurement.

Selection Notes

Select this component when interfacing mixed voltage logic families requiring a single-supply solution. The X2SON5 package offers a compact form factor suitable for space-constrained designs. Verify that the input signal rise and fall rates comply with the specified transition limits to maintain signal integrity across the translation boundary.

Part Context

This part belongs to the 74LV1T34 family of single supply translating buffers manufactured by Nexperia. The GXH suffix specifically denotes the X2SON5 plastic thermal enhanced extremely thin small outline package variant. This family is designed to bridge communication gaps between low-voltage controllers and higher-voltage peripherals in mixed-signal environments.

Replacement Considerations

The 74LV1T34GV serves as a pin-compatible alternative utilizing the SC-74A package. Designers must verify mechanical footprint compatibility and re-evaluate thermal dissipation characteristics due to differences in package surface area and heat transfer properties between the X2SON5 and SC-74A configurations.
