74AXP1T125 NRND

Dual supply buffer/line driver; 3-state

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 (V_CCI and V_CCO). A HIGH level at pin OE causes the output to assume a high-impedance OFF-state. The inputs are referenced to V_CCI and the output is referenced to V_CCO. All inputs can be connected directly to V_CCI or GND. V_CCI can be supplied at any voltage between 0.7 V and 2.75 V and V_CCO 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 I_OFF. The I_OFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

Not recommended for new designs (NRND).

Features and benefits
