SN74ALVC245数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

This octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation.
The SN74ALVC245 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 on the logic level at the direction-control (DIR) input. The output-enable (OE)\\ input can be used to disable the device so the buses are effectively isolated.
To ensure the high-impedance state during power up or power down, OE\\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
