To avoid drawing V

current out of terminal Z, when switch current flows into terminals Y, the
voltage drop across the bidirecctional switch must not exceed 0,4 V. If the switch current flows
into terminal Z, no V
DD
current will flow out of terminals Y, in this case there is no limit for the
voltage drop across the switch, but the voltages at Y and Z may not exceed V
