SN74ALVCH16863 Datasheet | Texas Instruments

description 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 munication 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.

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.
