74LV1T125GXH

Overview

The Nexperia 74LV1T125GXH 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 logic levels at 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device facilitates both up-translation (e.g., 1.8 V to 3.3 V) and down-translation (e.g., 3.3 V to 1.8 V). It includes 5 V tolerant inputs and provides propagation delays as low as 3.6 ns at 5.0 V with a 30 pF load. The component is housed in an X2SON-5 package and functions across temperatures from -40 °C to +125 °C.

Feature Summary

• Supports bidirectional level translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V CMOS logic families
• Features 5 V tolerant inputs allowing direct interfacing with higher voltage sources
• Includes 3-state output controlled by an enable input for bus management
• Provides high noise immunity and robust latch-up protection exceeding 250 mA

Applications

• Portable applications
• PC and notebook systems
• Industrial controllers
• Telecom equipment

Procurement Notes

Verify the specific ordering suffix 'GXH' corresponds to the X2SON-5 (SOT1226-3) package variant when sourcing. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure input signal rise and fall rates remain within the recommended 20 ns/V transition rate to maintain timing specifications. Check for any recent Product Change Notifications regarding marking or assembly updates.

Selection Notes

Select this component for designs requiring a single-supply translator to bridge different voltage domains without complex circuitry. The 3-state output allows integration into shared data buses where multiple drivers must coexist. Verify that the maximum supply voltage does not exceed 5.5 V to prevent damage. Consider the thermal dissipation capabilities if operating near the upper temperature limits.

Part Context
