The 74AXP1T34GWH from Nexperia is a dual supply translating buffer in 5 pin TSSOP package. It features one input (A), an output (Y) 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 0.7V and 2.75V and VCCO can be supplied at any voltage between 1.2V and 5.5V. This feature allows voltage level translation. Schmitt-trigger action at all inputs makes circuit tolerant of slower input rise and fall times. It ensures very low static and dynamic power consumption across entire supply range and is fully specified for partial power down applications using IOFF. The IOFF circuitry disables output, preventing the potentially damaging backflow current through device when it is powered down.
