74AXP1T125GS数据手册集成电路（IC）的转换器电平移位器规格书PDF

描述 Description

The 74AXP1T125 is a dual supply non-inverting buffer/line driver with 3-state output. It features one input (A), an output (Y), an output enable input (OE) and dual supply pins (VCCI and VCCO). A HIGH level at pin OE causes the output to assume a high-impedance OFF-state. 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. This feature allows voltage level translation.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device ensures very low static and dynamic power consumption across the entire supply range and is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
