Product Summary
The SN74LV245ARGYR is an octal bus transceiver. The SN74LV245ARGYR is designed for 2-V to 5.5-V VCC operation. The SN74LV245ARGYR 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.
