The SN74LVC8T245MPWREP is a 8-bit dual-supply Bus Transceiver with configurable voltage translation and 3-state outputs. The non-inverting bus transceiver uses two separate configurable power-supply rails. It is optimized to operate with VCCA and VCCB set at 1.65 to 5.5V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65 to 5.5V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.8, 2.5, 3.3 and 5.5V voltage nodes. It is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode.
Control inputs VIH/VIL levels are referenced to VCCA voltage
VCC isolation feature - if either VCC input is at GND, all are in the high-impedance state
Fully configurable dual-rail design allows each port to operate
Latch-up performance exceeds 100mA per JESD 78, class II
