The is a 8-bit dual supply Translating Transceiver that enables bidirectional level translation. It features two 8-bit input-output ports, a direction control input, an output enable input and dual supply pins. Both VCCA and VCCB can be supplied at any voltage between 0.8 and 3.6V making the device suitable for translating between any of the low voltage nodes. Pins An, OE and DIR are referenced to VCCA and pins Bn are referenced to VCCB. A HIGH on DIR allows transmission from An to Bn and a LOW on DIR allows transmission from Bn to An. The output enable input OE can be used to disable the outputs so the buses are effectively isolated. 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 VCCA or VCCB are at GND level, both An and Bn outputs are in the high-impedance OFF-state.
