... C-compatible interface. Standard, full speed, and high speed (3.4 MHz) I simultaneous switch combination is allowed. An additional feature of the ADG2188 is that switches can be updated simultaneously, using the LDSW command. In addition, a RESET option allows all of the switch channels to be reset/off. At power on, all switches are in the off condition. ...

... See the Ordering Guide for details. SERIAL BUS ADDRESS The ADG2188 has a 7-bit slave address. The four MSBs are hard coded to 1110, and the three LSBs are determined by the state of Pin A0, Pin A1, and Pin A2. By offering the facility to hardware configure Pin A0, Pin A1, and Pin A2 eight of these devices can be connected to a single serial bus ...
