Description

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 VCCthrough 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.
