74LVC1G125GM,132

Overview

The Nexperia 74LVC1G125GM,132 is a single bus buffer and line driver featuring a non-inverting logic function with three-state outputs. 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 at all inputs for improved noise immunity and slow signal transition tolerance. It includes dedicated IOFF circuitry that disables the output during partial power-down conditions to prevent damaging backflow currents. The component is housed in an XSON6 package (SOT886) and is rated for operation across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Features Schmitt-trigger inputs to ensure high noise immunity and tolerance for slower input rise and fall times.
• Includes IOFF circuitry to disable outputs during partial power-down applications, preventing potentially damaging backflow currents.
• Provides direct interface capability with TTL levels while maintaining compatibility with mixed 3.3 V and 5 V environments.

Applications

• Partial power-down mode operations requiring isolation of powered-down sections
• Bus-oriented communications systems requiring signal buffering
• Mixed-signal translation between 3.3 V and 5 V logic domains

Selection Notes

Select this component when a single-channel buffer with three-state control is required for low-voltage digital interfaces. The wide supply voltage range allows flexibility in system design, accommodating both 1.8 V and 5 V logic families. Ensure the application benefits from the included IOFF protection if the system utilizes partial power-down states. Verify that the XSON6 package dimensions align with the target PCB footprint constraints.

Part Context

This part belongs to the 74LVC family of CMOS logic devices, designed for low-voltage applications. The 74LVC1G125 series specifically addresses the need for single-buffer solutions in space-constrained designs. The GM variant denotes the XSON6 package type, which offers a compact form factor suitable for modern surface-mount assembly processes. This series complements other LVC components by providing standardized logic functions in ultra-small packages.

Replacement Considerations

Check for pin-compatible alternatives such as the 74LVC1G125GN or 74LVC1G125GS if different XSON6 body sizes are preferred. Verify functional equivalence with the 74LVC1G126GM if inverted logic is acceptable, though the 125 provides non-inverting functionality.
