74LVC1G126GW,165

Overview

The Nexperia 74LVC1G126GW,165 is a single buffer and line driver featuring a three-state output. It operates within a supply voltage range of 1.65 V to 5.5 V and accepts inputs from 3.3 V or 5 V devices. The device includes Schmitt-trigger action for noise immunity and IOFF circuitry for partial power-down protection. It is housed in a TSSOP5 (SOT353-1) package with five leads.

Feature Summary

• Provides non-inverting buffering with high noise immunity via Schmitt-trigger inputs
• Enables safe operation in mixed-voltage environments through overvoltage tolerant inputs
• Supports partial power-down applications by disabling outputs to prevent backflow current

Applications

• Translating signals between mixed 3.3 V and 5 V logic environments
• Driving bus lines with controlled three-state output capability
• Buffering signals requiring tolerance for slow input rise and fall times

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity and packaging variant. Confirm that the TSSOP5 package designation aligns with your PCB footprint requirements. Ensure the temperature range specification meets your operational environment constraints before finalizing procurement orders.

Selection Notes

Select this component when a single-channel buffer with three-state control is required. It is suitable for designs needing direct interface with TTL levels and wide supply voltage flexibility. Consider the TSSOP5 package dimensions if space constraints dictate a thin shrink small outline form factor.

Part Context

This part belongs to the 74LVC1G126 family of single buffers and line drivers. It shares functional characteristics with other variants in the series but differs in physical packaging. The GW suffix specifically denotes the TSSOP5 plastic thin shrink small outline package configuration.

Replacement Considerations

Direct substitutes include other 74LVC1G126 variants such as 74LVC1G126GV, 74LVC1G126GM, and 74LVC1G126GS. These alternatives offer identical electrical performance but utilize different package types like SC-74A or XSON6.
