Additional Details

The PI74LPT245Q operates from a single 5V power supply. It provides high-current drive capability, allowing it to drive heavily loaded buses. The direction of data flow is controlled by a direction-control (DIR) input. A separate output enable (OE) input allows the outputs to be placed in a high-impedance state for bus isolation. The device is characterized for operation over the industrial temperature range. Specific propagation delays, supply current characteristics, and package options should be verified using the manufacturer's datasheet.
