The SN74AVC32T245ZKER is a 32-bit dual-supply Bus Transceiver with configurable voltage translation and 3-state outputs. It uses two separate configurable power-supply rails. The SN74AVC32T245 device is optimized to operate with VCCA/VCCB set from 1.4 to 3.6V. It is operational with VCCA/VCCB as low as 1.2V. The A port is designed to track VCCA. VCCA and accepts any supply voltage from 1.2 to 3.6V. The B port is designed to track VCCB. VCCB and accepts any supply voltage from 1.2 to 3.6V. It is designed for asynchronous communication between data buses. 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 at the direction-control (DIR) input. The OE\ input can disable the outputs so the buses are effectively isolated. This device is fully specified for partial-power-down applications using Ioff.
