The PI74LVC3245A is a non-inverting 8-bit Bidirectional Transceiver that uses two seperate power supply rails. A-port (VCCA) is set to operate at 3.3V and B-port (VCCB) is set to operate at 5V. This allows for translation from a 3.3V to a 5Venvironment and vice-versa. This tranceiver is designed for asynchronous two-way communication between data buses. The direction control input pin (DIR) determines the dataflow from the A bus to the B bus or from the B bus to the A bus. The output enable (OE) input, when HIGH, disables both A and B ports by placing them in HIGH Z condition.
