SN74ABT640 具有三态输出的八路总线收发器
SN74ABT640 描述
The 'ABT640 bus transceivers are designed for asynchronous communication between data buses. These devices transmit inverted data from the A bus to the B bus or from the B bus to the A bus, depending on the level at the direction-control (DIR) input. The output-enable (
) input can be used to disable the device so that the buses are effectively isolated.
To ensure the high-impedance state during power up or power down, 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.
The SN54ABT640 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT640 is characterized for operation from -40°C to 85°C
