description

This 8-bit (octal) noninverting bus transceiver contains two separate supply rails. The B port is designed to track V_CCB, which accepts voltages from 3 V to 5 V, and the A port is designed to track V_CCA, which is set to operate at 3.3 V. This allows for translation from a 3.3-V to a 5-V environment and vice versa.

The SN74LVCC3245 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 output-enable () input can be used to disable the device so the buses are effectively isolated.

The SN74LVCC3245 is characterized for operation from -40°C to 85°C.
