The TC74AC245P functions as either a buffer or a transceiver, controlled by the direction control (DIR) input. When DIR is high, data flows from the A inputs to the B outputs. Conversely, when DIR is low, data flows from the B inputs to the A outputs. The output enable (OE) input determines whether the outputs are active or in a high-impedance state. A low level on OE enables the outputs, while a high level disables them, effectively isolating the device from the bus. The device operates over a temperature range of -40°C to +85°C.
