74LVC1G126GW,125

Overview

The Nexperia 74LVC1G126GW,125 is a single bus buffer and line driver featuring a three-state output, housed in a TSSOP5 (SOT353-1) package. It operates within a supply voltage range of 1.65 V to 5.5 V. The device supports overvoltage tolerant inputs up to 5.5 V and includes Schmitt-trigger action for noise immunity. It incorporates IOFF circuitry for partial power-down mode operation, preventing backflow current. The component complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36, and offers ESD protection exceeding 2000 V HBM.

Feature Summary

• Provides non-inverting buffering with high-noise-immunity Schmitt-trigger inputs
• Enables safe mixed-voltage translation between 3.3 V and 5 V logic domains
• Supports partial power-down applications via integrated IOFF circuitry

Applications

• Mixed 3.3 V and 5 V system environments
• Partial power-down applications requiring backflow prevention
• Bus buffering and line driving operations

Procurement Notes

Verify the specific ordering suffix '125' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required temperature range and package dimensions. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and compliance with RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when a single-channel, non-inverting buffer with three-state control is required. It is suitable for designs needing direct interface with TTL levels and CMOS low power dissipation. Consider the TSSOP5 package constraints and verify that the operating voltage aligns with the 1.65 V to 5.5 V specification. Ensure input transition rates comply with recommended operating conditions for the target supply voltage.

Part Context

This device belongs to the 74LVC family of low-voltage CMOS logic components manufactured by Nexperia. It serves as a general-purpose buffer designed for portable and battery-operated applications due to its wide supply voltage range. The GW suffix specifically denotes the TSSOP5 plastic thin shrink small outline package variant, distinguishing it from other package options like XSON or SC-74A within the same logical family.

Replacement Considerations

Direct substitutes include other 74LVC1G126 variants with different packages, such as 74LVC1G126GV (SC-74A), 74LVC1G126GM (XSON6), or 74LVC1G126GX (X2SON5). Verify pinout compatibility and thermal characteristics when substituting across package types.
