OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS

This octal Bus Transceiver SN74LVCH245 is designed for 2.7-V to 3.6-V VCC operation; it CAN Interface to a 5-V system environment. 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 VCC 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 40C to 85C By Texas Instruments
