Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3V beyond the supply rails should be current-limited to 10mA or less.

The switches are bidirectional, so the NO, NC, and COM pins can be used as either inputs or outputs. Pull the digitally controlled input select pin IN to V CC or GND to avoid unwanted switch states that could result if the logic control pin is left floating. 5V V+ System Digital Control Signal Path INx NOx Device 1 NCx Device 2 5V COMx 5V GND Figure 12.
