Dual supply single buffer and single buffer with open-drain, The 74AXP2T3407 is a dual supply single buffer and a single buffer with open-drain output. It features two input pins (nA), an output pin (1Y) and an open-drain output pin (2Y) and dual supply pins (VCCI and VCCO). The inputs are referenced to VCCI and the output is referenced to VCCO. All inputs can be connected directly to VCCI or GND. VCCI can be supplied at any voltage between 0.7 V and 2.75 V and VCCO can be supplied at any voltage between 1.2 V and 5.5 V.

High noise immunity
Inputs accept voltages up to 2.75 V
Low noise overshoot and undershoot < 10% of VCCO
IOFF circuitry provides partial power-down mode operation
