SN74AVC32T245 Dual-Supply Bus Transceiver Texas Instruments SN74AVC32T245 Dual-Supply Bus Transceiver is a 32-bit non-inverting bus transceiver that uses two separate, configurable power-supply rails. The SN74AVC32T245 is optimized to operate with VCCA/VCCB set from 1.4V to 3.6V. It is operational with VCCA/VCCB as low as 1.2V. The A port is designed to track VCCA and accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB and accepts any supply voltage from 1.2V to 3.6V. This feature allows for universal low-voltage bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V voltage nodes.
