Notes
1. H = HIGH state (the more positive voltage)
L = LOW state (the less positive voltage)
X = state is immaterial

Supply voltage (with reference to V

Note
1. To avoid drawing V
DD
current out of terminal Z, when switch current flows into terminals Y, the voltage drop across
the bidirectional 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
