Description

The AWS74AVC8T245 is an 8-bit, dual supply transceiver that enables bidirectional bus transceiver supporting configurable voltage translation. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level of the DIR input. OEB inputs are used to disable the outputs so the buses are effectively isolated. Both VCCA and VCCB can be supplied at any voltage between 0.65V and 3.6V making the device suitable for bidirectional translating among any of the 0.8V, 1.2V, 1.5V, 1.8V, 2.5V and 3.3V voltage nodes. The An, OEB and DIR pins are referenced to VCCA and Bn pins are referenced to VCCB. 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 are in the high-impedance OFF-state.
