SN74LS245 数据手册

The SN74LS245 is an Octal Bus Transmitter/Receiver designed for

8-line asynchronous 2-way data communication between data buses.

Direction Input (DR) controls transmission of Data from bus A to bus

B or bus B to bus A depending upon its logic level. The Enable input

(E) can be used to isolate the buses.
