SN74AUC1G126DBVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G126DBVR 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 back-drive 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

• Supports partial power-down applications via Ioff circuitry to inhibit damaging backflow currents when powered down.
• Features overvoltage-tolerant inputs allowing signals above the supply voltage without exceeding absolute maximum ratings.
• Provides balanced CMOS push-pull outputs capable of sinking and sourcing similar currents for fast edge rates.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix DBVR corresponds to the SOT-23 package configuration required for your design. Confirm that the RoHS compliance status and lead finish match your manufacturing process requirements. Ensure the operating temperature range of -40°C to 85°C aligns with your system's thermal environment specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel non-inverting buffer with tri-state control is needed in ultra-low voltage environments. It is suitable for designs requiring high-speed signal buffering with minimal power consumption. The overvoltage tolerance allows interfacing with 3.6 V logic levels while powered by lower voltages. Consider the small footprint if space-constrained PCB layouts are a priority.
