74LV1T34GV-Q100H

Overview

The Nexperia 74LV1T34GV-Q100H is a single supply translating buffer qualified to AEC-Q100 Grade 1. It operates within a supply voltage range of 1.6 V to 5.5 V and supports 1.8 V, 2.5 V, 3.3 V, and 5.0 V CMOS levels. The device features low threshold inputs for 1.8 V logic at VCC = 3.3 V and 5 V tolerant input pins. Propagation delay ranges from 3.6 ns to 12.8 ns depending on load capacitance and voltage. Operating temperature spans -40 °C to +125 °C.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• Single supply voltage translation supporting multiple CMOS levels
• 5 V tolerant inputs enabling level down translation

Applications

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

Procurement Notes

Verify the specific package variant against project requirements. The 'GV' suffix indicates the SC-74A (SOT753) package. Confirm that the AEC-Q100 Grade 1 qualification aligns with automotive reliability standards. Ensure design margins accommodate the specified operating temperature range and power dissipation limits under actual load conditions.

Selection Notes

Select this component when a single-channel translator is required for mixed-voltage interfaces. The wide supply range allows flexibility between 1.8 V and 5.0 V systems. Consider the propagation delay specifications relative to signal integrity requirements. Verify that the 5 V tolerant inputs are sufficient for interfacing with higher voltage logic sources without external protection.

Part Context

This part belongs to the 74LV1T34-Q100 family of single supply translating buffers. The GV suffix specifically denotes the SC-74A plastic surface-mounted package with five leads. It shares functional characteristics with other variants like the GW version but differs in physical footprint and thermal properties.

Replacement Considerations

The 74LV1T34GW-Q100H serves as a direct functional substitute using the TSSOP5 package.
