74LVC1G125DCKTG4

Overview

The SN74LVC1G125DCKTG4 is a single bus buffer gate with three-state output from the Texas Instruments LVC logic family. It operates within a supply voltage range of 1.65 V to 5.5 V and features non-inverting polarity. The device provides an output drive capability of ±32 mA at 3.3 V and maintains low power consumption with a maximum static current of 10 µA. It supports partial-power-down mode via Ioff circuitry, which disables outputs to prevent backflow during power-down states. The component is housed in a SC-70-5 package and is rated for operation between -40°C and +125°C.

Feature Summary

• Supports 5-V VCC operation while accepting input voltages up to 5.5 V
• Enables partial-power-down applications through dedicated Ioff circuitry
• Provides robust ESD protection exceeding JESD 22 standards

Applications

• Portable consumer electronics requiring low-voltage operation
• Battery-powered systems utilizing partial-power-down modes
• High-density board layouts using compact NanoStar or NanoFree packages

Procurement Notes

Verify the G4 suffix indicates lead-free construction and RoHS compliance when sourcing. Confirm the DCKT designation corresponds to the SC-70-5 tape-and-reel packaging format. Ensure the specific revision matches the required datasheet version for timing characteristics. Cross-reference ordering information to validate availability against standard distribution channels.

Selection Notes

Select this component for designs requiring a single-channel buffer with high drive strength in minimal space. The wide supply voltage range accommodates various logic levels without level shifting. Consider the SC-70-5 footprint for space-constrained PCB layouts. Verify thermal requirements align with the specified operating temperature range for the target environment.

Part Context

This part belongs to the SN74LVC1G125 series of single bus buffers. It utilizes Texas Instruments' NanoStar and NanoFree package technologies, which integrate the die directly into the package structure. This approach significantly reduces physical size compared to traditional packages while maintaining electrical performance suitable for modern portable devices.
