1. General description

The 74ABT245 is an 8-bit transceiver with 3-state outputs. The device features an output enable

(OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a

high-impedance OFF-state. This device is fully specified for partial power down applications using

IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current

through the device when it is powered down.

2. Features and benefits
