description

This octal bus transceiver is designed for 2.7-V to 3.6-V V

environment.

operation; it can interface to a 5-V system

The SN74LVCH245 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 upon 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.

To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

The SN74LVCH245 is characterized for operation from –40°C to 85°C.
