74LV1T126GW-Q100H

Overview

The Nexperia 74LV1T126GW-Q100H is a single supply translating buffer and line driver featuring a 3-state output, qualified to AEC-Q100 Grade 1 standards for automotive use. It operates within a supply voltage range of 1.6 V to 5.5 V. The device supports 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 (A to Y) ranges from 3.2 ns to 9.6 ns depending on load capacitance.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• Wide operating temperature range specified from -40 °C to +125 °C
• Supports both up-translation and down-translation between standard CMOS levels
• Features 5 V tolerant inputs and latch-up performance exceeding 250 mA per JESD 78 Class II

Applications

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

Procurement Notes

Verify the specific suffix 'GW' corresponds to the TSSOP5 package (SOT353-1) and the '-Q100H' indicates AEC-Q100 Grade 1 automotive qualification. Confirm that the ordering code matches the required temperature range of -40 °C to +125 °C. Ensure compatibility with the intended supply voltage levels for translation requirements before finalizing procurement.

Selection Notes

Select this component when a single-channel level translator with 3-state control is required for automotive or industrial environments. It is suitable for interfacing between different voltage domains such as 1.8 V, 2.5 V, 3.3 V, and 5.0 V. Consider the propagation delay specifications relative to the system clock speed and load capacitance to ensure signal integrity across the translation boundary.

Part Context

This part belongs to the 74LV1T126-Q100 family of single supply translating buffers. It is designed to bridge logic levels in mixed-voltage systems. The device integrates low threshold inputs to facilitate level shifting while maintaining high noise immunity through Schmitt-trigger-like characteristics inherent in the LV series technology.
