74LV1T125GWH

Overview

The Nexperia 74LV1T125GWH 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 CMOS logic levels at 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device provides up-translation capabilities from input voltages as low as 1.2 V to 1.8 V, and down-translation from 3.3 V or 5.0 V inputs. It includes 5 V tolerant inputs and offers latch-up performance exceeding 250 mA per JESD 78 Class II. The component is specified for ambient temperatures ranging from -40 °C to +125 °C.

Feature Summary

• Provides single-supply level translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V systems
• Features 5 V tolerant inputs allowing operation in mixed-voltage environments
• Includes 3-state output controlled by an independent OE pin for bus isolation
• Supports partial power-down mode via I_OFF circuitry to prevent backflow current

Applications

• Portable applications
• PC and notebook computers
• Industrial controllers
• Telecommunications equipment

Procurement Notes

Verify the specific package suffix against the ordering information table to ensure correct physical dimensions and lead configuration. Confirm that the required temperature range matches the -40 °C to +125 °C specification. Check for automotive qualification requirements, as this standard part is not AEC-Q100 qualified. Ensure design safeguards are implemented for ESD protection compliance.

Selection Notes

Select this component when interfacing between different voltage domains requiring non-inverting buffering with high impedance states. It is suitable for applications needing both up-translation and down-translation on a single supply rail. Consider the 5 V tolerant input feature if driving signals originate from higher voltage sources than the operating VCC.

Part Context

This device belongs to the 74LV series of low-voltage CMOS logic components manufactured by Nexperia. It functions as a single-channel translator designed to bridge communication gaps between various digital logic families. The GWH suffix indicates the TSSOP5 (SOT353-1) plastic thin shrink small outline package variant.

Replacement Considerations

The 74LV1T126GXH is listed as a parameter-equivalent substitute.
