SN74AUC1G126YZPR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G126YZPR is a single bus buffer gate with tri-state output from the Texas Instruments AUC logic series. It operates within a supply voltage range of 0.8 V to 2.7 V, specifically optimized for 1.65 V to 1.95 V operation. The device features overvoltage-tolerant inputs capable of handling up to 3.6 V, supporting mixed-mode signal environments. It provides an output drive current of ±8 mA at 1.8 V and achieves a maximum propagation delay of 2.5 ns at 1.8 V. Packaged in a DSBGA-5 (NanoFree) format, it supports partial power-down modes via Ioff circuitry.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix YZPR corresponds to the DSBGA package type when sourcing components. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Ensure design layouts account for the thermal resistance characteristics unique to the NanoFree package form factor.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low-voltage operation below 1.8 V where standard logic families may not function correctly. The inclusion of an output enable pin allows for precise control of data flow on shared buses. Consider the small physical footprint of the DSBGA package for space-constrained portable electronics designs.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial power-down conditions?

The device incorporates Ioff circuitry that forces inputs and outputs into a high-impedance state when the supply voltage drops to 0 V, thereby inhibiting current backflow.

What is the maximum input voltage tolerance?

The inputs are overvoltage tolerant and can withstand signals up to 3.6 V, even when the device supply voltage is lower than this threshold.
