Product Overview
The SN74AUP1G125 is a Texas Instruments single bus buffer gate for Signal_Chain designs requiring a single line driver with a 3-state output. Its output-enable input is active low, and the output is disabled when OE is high, allowing the output node to enter a high-impedance state.
The recommended supply range is 0.8 V to 3.6 V, with operation specified across -40°C to 85°C free-air temperature. Input thresholds vary by VCC range, including high-level input requirements from VCC to 3.6 V at 0.8 V supply and up to 2 V to 3.6 V for 3 V to 3.6 V operation. Output voltage is specified from 0 to VCC in the active state and 0 to 3.6 V in 3-state operation.
Package coverage includes SOT-23, SC70, SOT, SON, DSBGA, and X2SON sizes. Electrical limits include ±20 mA continuous output current, ±50 mA through VCC or GND, 0.5 µA maximum input leakage, 0.6 µA maximum power-off leakage, and less than 10% of VCC output overshoot and undershoot.
