1. General description
The 74AUP1T02 provides the single 2-input NOR 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 74AUP1T02 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.
