MC74F2245中文资料摩托罗拉数据手册PDF规格书

The MC74F2245 is designed for asynchronous communication between data buses. The device transmits 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.

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

The MC74F2245 is characterized for operation from 0°C to 70°C.
