TEXAS INSTRUMENTS SN74HCT245NSR 收发器, 非反相, 3态, 4.5V至5.5V, SOP-20
The is an octal Bus Transceiver with 3-state outputs and designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The HCT245 device allows data transmission 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 can be used to disable the device so that the buses are effectively isolated.
