74LVC1G126GV,125

Overview

The Nexperia 74LVC1G126GV,125 is a single bus buffer and line driver featuring a 3-state output, housed in the SC-74A (SOT753) surface-mount package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports overvoltage tolerant inputs up to 5.5 V. The device incorporates Schmitt-trigger action for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down states. It provides an output drive capability of ±24 mA at VCC = 3.0 V and ensures latch-up performance exceeding 250 mA.

Feature Summary

• Features Schmitt-trigger inputs to tolerate slower rise and fall times
• Includes IOFF circuitry for safe partial power-down operation
• Provides high noise immunity with CMOS low power dissipation
• Supports direct interface with TTL logic levels

Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Driving bus lines with controlled 3-state outputs
• Buffering signals from 3.3 V or 5 V devices

Procurement Notes

Verify the specific ordering suffix GV, which designates the SC-74A (SOT753) plastic surface-mounted package with five leads. Confirm that the required temperature range matches the -40 °C to +125 °C specification listed for this variant. Ensure the application environment does not exceed the absolute maximum ratings defined in the datasheet limiting values section.

Selection Notes

Select this component when a single-channel non-inverting buffer with 3-state control is required. It is suitable for applications needing direct interfacing with TTL levels or translation between different voltage domains. Consider the SC-74A package dimensions if board space allows for this specific footprint compared to smaller XSON alternatives.

Part Context

This part belongs to the 74LVC1G126 family of single bus buffers. Other variants include the GW (TSSOP5), GM (XSON6), GN (XSON6), GS (XSON6), GX (X2SON5), and GZ (XSON5) packages. All share identical electrical characteristics but differ in physical form factor and thermal properties.

Replacement Considerations

Direct pin-compatible replacements within the same family include other package variants such as 74LVC1G126GW, 74LVC1G126GM, 74LVC1G126GN, 74LVC1G126GS, 74LVC1G126GX, and 74LVC1G126GZ.
