7.2 Shutdown function

The CBTL06DP211 provides a shutdown function to minimize power consumption when

the application is not active but power to the CBTL06DP211 is provided. Pin XSD (active

LOW) puts all channels in off mode (non-conducting high-impedance state) while reducing

current consumption to near-zero.
