description/ordering information
This octal bus transceiver is designed specifically for low-voltage (3.3-V) V operation, but with the capability
CC
to provide a TTL interface to a 5-V system environment.
The SN74LVT245B is designed for asynchronous communication between data buses. The device transmits
data 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 the buses are
effectively isolated.
