74LVC1G126GM,115

Overview

The Nexperia 74LVC1G126GM,115 is a single buffer and line driver featuring a three-state output, housed in an XSON6 (SOT886) 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 ±24 mA output drive at 3.0 V and complies with JEDEC standards for various voltage levels.

Feature Summary

• Provides non-inverting buffering with three-state output capability for bus driving applications
• Features IOFF circuitry to disable outputs and prevent damaging backflow currents when powered down
• Includes Schmitt-trigger inputs to ensure tolerance against slow input rise and fall times
• Supports direct interface with TTL logic levels across the full operating voltage range

Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Driving high-capacitance or low-impedance loads on buses
• Partial power-down mode operation in portable systems

Procurement Notes

Verify that the ordering suffix ,115 corresponds to the XSON6 (SOT886) package variant. Confirm the temperature range specification matches the design requirement, as this part number is specified from -40 °C to +125 °C. Ensure input transition rates comply with recommended operating conditions to maintain signal integrity.

Selection Notes

Select this component when a single-channel, non-inverting buffer with controlled output enable is required. The inclusion of IOFF functionality makes it suitable for systems requiring safe isolation during power transitions. Verify that the XSON6 package dimensions fit the available PCB footprint constraints compared to other available package options.

Part Context

This device belongs to the 74LVC1G126 family of single buffers. The GM suffix specifically denotes the XSON6 plastic extremely thin small outline package with no leads. Other variants in the series include TSSOP5, SC-74A, and XSON5 packages, offering flexibility for different board space and thermal requirements.

Replacement Considerations

The 74LVC1G125GM,115 is a parameter-equivalent alternative within the same package, differing only by having an inverted output function instead of non-inverting.
