description

The 'ABT640 bus transceivers are designed for asynchronouscommunication between data buses. These devices transmit inverteddata 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. Theoutput-enable () input can beused to disable the device so that the buses are effectivelyisolated.

To ensure the high-impedance state during power up or power down,should be tiedto V_CC through a pullup resistor; the minimum value of theresistor is determined by the current-sinking capability of thedriver.

The SN54ABT640 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. TheSN74ABT640 is characterized for operation from -40°C to85°C.
