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 (OE) 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, 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.
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.
