产品概述
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.
