DESCRIPTION/ORDERING INFORMATION

This octal bus transceiver is designed for asynchronous two-way communication between data buses. The

control-function implementation minimizes external timing requirements.

The SN74LV245AT allows data transmission from the A bus to the B bus or from the B bus to the A bus,

depending on 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.
