74LVC1G34GV,125

Overview

The Nexperia 74LVC1G34GV,125 is a single non-inverting buffer in the LVC logic family. It operates within a supply voltage range of 1.65 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device includes IOFF circuitry for partial power-down protection. It utilizes an SC-74A (SOT753) package with five leads. Operating temperatures extend from -40 °C to +125 °C.

Feature Summary

• Schmitt-trigger action at all inputs provides tolerance for slower input rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow currents.
• Inputs are overvoltage tolerant up to 5.5 V, enabling direct interface with TTL levels.

Applications

• Translators in mixed 3.3 V and 5 V environments
• Partial power-down applications requiring backflow current prevention
• Signal buffering where slow input transitions occur

Procurement Notes

Verify the ordering suffix matches GV,125 to confirm the SC-74A package type. Confirm the revision history aligns with Rev. 11 dated November 13, 2024. Ensure the temperature range specification meets the required operational limits of -40 °C to +125 °C before procurement.

Selection Notes

Select this component when a single-channel non-inverting buffer is required with Schmitt-trigger inputs. It is suitable for designs needing overvoltage tolerant inputs up to 5.5 V while operating on lower supply voltages. The inclusion of IOFF circuitry makes it appropriate for systems requiring partial power-down modes.
