74AUP1T45GW: Low-power dual supply translating transceiver; 3-state

The 74AUP1T45 is a single bit transceiver featuring two data input-outputs (A and B), a direction control input (DIR) and dual supply pins (VCC(A) and VCC(B)) which enable bidirectional level translation. Both VCC(A) and VCC(B) can be supplied at any voltage between 1.1 V and 3.6 V making the device suitable for interfacing between any of the low voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins A and DIR are referenced to VCC(A) and pin B is referenced to VCC(B). A HIGH on DIR allows transmission from A to B and a LOW on DIR allows transmission from B to A.

Schmitt trigger action on all inputs makes the circuit tolerant of slower input rise and fall times across the entire VCC(A) and VCC(B) ranges. The device ensures low static and dynamic power consumption and is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when either VCC(A) or VCC(B) are at GND, both A and B are in the high-impedance OFF-state.
