The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2 V to 3.6 V. The SN74AVCH4T245 is optimized to operate with VCCA/VCCB set at 1.4 V to 3.6 V. It is operational with VCCA/VCCB as low as 1.2 V. This allows for universal low voltage bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V voltage nodes. Control Inputs VIH/VIL Levels are Referenced to VCCA Voltage Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.2V to 3.6V PowerSupply Range I/Os Are 4.6V Tolerant Ioff Supports Partial Power-Down-Mode Operation Bus Hold on Data Inputs Eliminates the Need for External pull-up/pull-down Resistors Max Data Rates – 380 Mbps (1.8 V to 3.3 V Translation) – 200 Mbps (
