Low-power buffer with voltage-level translator

The 74AUP1T50 provides the single buffer function. This device ensures a very low static and dynamic power consumption across the entire VCC range from 2.3 V to 3.6 V.

The 74AUP1T50 is designed for logic-level translation applications with input switching levels that accept 1.8 V low-voltage CMOS signals, while operating from either a single 2.5 V or 3.3 V supply voltage.

The wide supply voltage range ensures normal operation as battery voltage drops from 3.6 V to 2.3 V.

This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.

Schmitt trigger inputs make the circuit tolerant to slower input rise and fall times across the entire VCC range.
