... These parts can operate equally well as either multiplexers, demultiplexers or switch arrays and the input signal range extends to the supplies. The ADG728 and ADG729 utilize a 2-wire serial interface that 2 is compatible with the I C™ interface standard. Both have two external address pins (A0 and A1) ...

... The ADG728/ADG729 have different 7-bit slave addresses. The five MSBs of the ADG728 are 10011, while the MSBs of the ADG729 are 10001 and the two LSBs are determined by the state of the A0 and A1 pins. The 2-wire serial bus protocol operates as follows: 1 ...

... MASTER READ OPERATION When reading data back from the ADG728/ADG729, the user must begin with an address byte and R/W bit, after which the ma- trix switch will acknowledge that it is prepared to transmit data by pulling SDA low. The readback operation is a single byte that consists of the eight data bits in the input register ...

... Each has a different slave address since the state of their A0 and A1 pins is different. This allows each Matrix Switch to be writ- ten to or read from independently. Because the ADG729 has a different address to the ADG728, it would be possible for four of each of these devices to be connected to the same bus. ...
