The 74LVC2T45DC,125 is a dual supply Translating Transceiver with 3-state outputs that enable bidirectional level translation. It features two 2-bit input-output ports, a direction control input and dual supply pins. Both VCC(A) and VCC(B) can be supplied at any voltage between 1.2 and 5.5V making the device suitable for translating between any of the low voltage nodes. Pins nA and DIR are referenced to VCC(A) and pins nB are referenced to VCC(B). A HIGH on DIR allows transmission from nA to nB and a LOW on DIR allows transmission from nB to nA. The device 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 level, both A port and B port are in the high-impedance OFF-state.
