74LV1T125GVH

Overview

The Nexperia 74LV1T125GVH is a single supply translating buffer and line driver featuring a 3-state output. It operates within a supply voltage range of 1.6 V to 5.5 V, supporting input logic levels from 1.8 V at VCC = 3.3 V and enabling down translation to 2.5 V outputs at VCC = 2.5 V. The device provides up translation capabilities across 1.8 V, 2.5 V, 3.3 V, and 5.0 V configurations. It includes 5 V tolerant inputs and meets ESD protection standards exceeding 2000 V (HBM) and 1000 V (CDM). The component is specified for ambient temperatures ranging from -40 °C to +125 °C.

Feature Summary

• Supports both up and down voltage level translation between standard CMOS logic levels
• Features 5 V tolerant inputs compatible with mixed voltage environments
• Includes 3-state output controlled by an independent OE pin for bus isolation
• Provides robust ESD protection meeting JEDEC Class 2 and C3 standards

Applications

• Portable electronic devices
• PC and notebook computer systems
• Industrial controller interfaces
• Telecommunications equipment

Procurement Notes

Verify the specific ordering suffix 'GV' corresponds to the SC-74A (SOT753) package variant when sourcing. Confirm that the required temperature range matches the -40 °C to +125 °C specification provided in the datasheet. Ensure design compatibility with the 5 V tolerant input characteristics if interfacing with higher voltage logic sources.

Selection Notes

Select this component for applications requiring unidirectional level shifting between different CMOS voltage domains. It is suitable for connecting controllers or processors operating at varying supply voltages. The low threshold inputs facilitate direct interfacing with 1.8 V logic even when powered at 3.3 V. Consider the 3-state capability for managing shared data buses effectively.

Part Context

This part belongs to the 74LV1T125 family of single-supply translating buffers. Other variants include the GW version in TSSOP5 and GX version in X2SON5 packages. All share identical electrical specifications but differ in physical footprint and thermal properties. The GV variant specifically utilizes the SC-74A surface-mount package.

Replacement Considerations

Direct substitutes include other 74LV1T125 variants such as 74LV1T125GW or 74LV1T125GX, provided the package form factor difference is acceptable for the PCB layout.
