This 18-bit bus transceiver is designed for 1.65-V to 3.6-V VCC operation.
The SN74ALVCH16863 is an 18-bit noninverting transceiver designed for synchronous communication between data buses. The control-function implementation minimizes external timing requirements.
The SN74ALVCH16863 can be used as two 9-bit transceivers or one 18-bit transceiver. They allow 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 output-enable (OEAB or OEBA) inputs.
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 SN74ALVCH16863 is characterized for operation from -40°C to 85°C.
