... Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS— ...

... Controls the switch connected to NO1_ close switch open switch. The MAX4548/MAX4549 are divided into five functional blocks: the control-logic block, three switch-matrix blocks, and the bias-resistor block (see Functional Diagram ). The control-logic block accepts commands through the serial interface and uses those commands to control the four remaining blocks ...

... while Tables 5 and 6 detail the format of the signals. The MAX4548 is a receive-only device and must be controlled by the bus master device. A bus master device communicates by transmitting the address byte of the slave device over the bus and then transmitting the desired information. Each transmission consists of a start condition, a command byte, a data byte or word, and finally a stop condition ...

... Serially Controlled, Triple 3x2 Audio/Video Crosspoint Switches Slave Address (Address Byte) The MAX4548 uses an 8-bit slave address. To select a slave address, connect A0 and GND. The MAX4548 has four possible slave addresses, thus a maximum of four of these devices may share the same 2-bit address bus ...
