V2=1.8V, V3=0.2V, V4=-1.4V and V5=-3V.
0.1mA is flown in or out to and from all COM and SEG terminals, and also to voltage drop occuring from terminals
V
out, while 0.1mA flow in when the output level is at V3, V4 or V5 level. This occurs when 5V or -5V is input to V
and V3 or to V2, V4, and V5 respectively.
