Overview
The SN74AUP1G126 is a low-power single bus buffer gate with tri-state output, part of Texas Instruments' AUP family. This device is designed to meet the industry's low-power needs, particularly in battery-powered portable applications. It operates across a wide supply voltage range of 0.8 V to 3.6 V, ensuring low static and dynamic power consumption, which enhances battery life. The SN74AUP1G126 features a single line driver with a 3-state output, enabling the output to be disabled when the output-enable (OE) input is low. This device is also fully specified for partial-power-down applications, preventing current backflow and potential damage to the device.
