74LVC1G125GW,125

Overview

The Nexperia 74LVC1G125GW,125 is a single buffer and line driver featuring three-state outputs, housed in a TSSOP5 (SOT353-1) package. It operates within a supply voltage range of 1.65 V to 5.5 V and accepts overvoltage tolerant inputs up to 5.5 V. The device provides an output drive capability of ±24 mA at 3.0 V and includes IOFF circuitry for partial power-down applications to prevent backflow current. It complies with JEDEC standards for various voltage levels and supports ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Provides single-channel buffering with high-noise immunity and Schmitt-trigger input action for tolerance of slow signal transitions.
• Enables direct interface with TTL levels and mixed 3.3 V/5 V environments through wide supply and input voltage ranges.
• Integrates IOFF circuitry to disable outputs during power-down, preventing potentially damaging backflow currents.

Applications

• Bus buffering in mixed 3.3 V and 5 V digital systems
• Line driving for high-speed data transmission
• Partial power-down mode operation in portable electronics

Procurement Notes

Verify the specific ordering suffix '125' corresponds to the TSSOP5 package variant as documented in the official Nexperia datasheet. Confirm that the required temperature range (-40 °C to +125 °C) aligns with your application constraints. Ensure design compatibility with the specified absolute maximum ratings to avoid device stress or permanent damage during operation.

Selection Notes

Select this component when a single-channel, three-state buffer is required for interfacing between different voltage domains. The TSSOP5 package offers a compact solution for space-constrained designs. Consider the IOFF feature if the system requires safe disconnection during power-down states to protect downstream components from back-powering.

Part Context

This part belongs to the 74LVC1G125 family of single bus buffers. The GW suffix specifically denotes the TSSOP5 plastic thin shrink small outline package with five leads. Other variants in the family include SC-74A and various XSON packages, offering flexibility in footprint selection while maintaining identical electrical performance characteristics across the series.

Replacement Considerations

Direct substitutes include other 74LVC1G125 variants such as 74LVC1G125GV (SC-74A), 74LVC1G125GM (XSON6), or 74LVC1G125GX (X2SON5). Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit and correct electrical connection.
