description

The SN74F2245 is designed for asynchronous

communication between data buses. The devices

transmit data from the A bus to the B bus or from

the B bus to the A bus depending upon the logic

level at the direction-control (DIR) input. The

output-enable (OE) input disables the device so

the buses are effectively isolated.

GND 10

Both A and B outputs can sink up to 12 mA; 25-Ω resistors are included in the lower output circuit to reduce

overshoot and undershoot.

The SN74F2245 is characterized for operation from 0°C to 70°C.
