description
The
′BCT640 bus transceiver is designed for
asynchronous
communication
between
data
buses. These devices transmit data from the A
bus to the B bus or from the B bus to the A bus
depending upon 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.
The SN54BCT640 is characterized for operation
over the full military temperature range of 55
°C
to 125
°C. The SN74BCT640 is characterized for
operation from 0
°C to 70°C.
