74AUC1G126DCKRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G126DCKRG4 is a single bus buffer gate with tri-state output from Texas Instruments. It operates at VCC voltages between 0.8 V and 2.7 V, optimized for 1.65 V to 1.95 V. The device features overvoltage-tolerant inputs up to 3.6 V, supporting mixed-mode signal operation. It includes Ioff circuitry for partial power-down mode to prevent backflow current. Maximum propagation delay is 2.5 ns at 1.8 V with a 30 pF load. Supply current is limited to 10 µA maximum.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features balanced CMOS push-pull outputs capable of sinking and sourcing similar currents.
• Includes Ioff circuitry that disables outputs during power-down to inhibit damaging current backflow.
• Inputs are overvoltage tolerant, allowing signals above the supply voltage without exceeding absolute maximum ratings.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the SC-70 (DCK) designation in the datasheet. Confirm the G4 suffix indicates lead-free and RoHS compliance as specified in the orderable addendum. Ensure the operating temperature range aligns with the -40°C to 85°C specification. Check for any specific handling requirements related to the NanoFree™ packaging technology.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with tri-state control is required for low-voltage logic systems. It is suitable for applications needing mixed-mode signal translation due to its 3.6-V input tolerance. Consider the sub-1 V operability and low power consumption for battery-powered or energy-efficient designs requiring high-speed signal buffering.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AUC1G126 family of single bus buffer gates. It utilizes Texas Instruments' NanoFree™ package technology, which uses the die as the package for minimal footprint. The device is designed specifically for 1.8-V operation but supports a wider voltage range. It is distinct from other logic families by its focus on ultra-low voltage and high-speed performance.
