The SNx4HCT245 octal bus transceivers are designed for asynchronous two-way communication
between data buses. The control-function implementation minimizes external timing
The SNx4HCT245 devices allow data transmission from the A bus to the B bus or from the B
bus to the A bus, depending upon the logic 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.
