description GND GND
This 18-bit bus transceiver is designed for 1.65-V
to 3.6-V VCC operation.
GND GND The SN74ALVCH16863 is an 18-bit noninverting 2B3 2A3 transceiver designed for synchronous 2B4 2A4 communication between data buses. The 2B5 2A5
control-function implementation minimizes VCC VCC external timing requirements. 2B6 2A6
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.
