Note: *1) Applies to the current value flown in terminal VDD when power is input as follows; VDD=5V, GND=0V, V1 = 3.75V,
V2 = 2.5V, V3 = 2.5V, V4 = 1.25V and V5 = 0V.
*2) Applied to the voltage drop occuring from terminals VDD, V1, V4 and V5 to each common terminal (C1-C16)
when 0.1mA is flown in or out to and from all COM and SEG terminals, and also to voltage drop occuring from
terminals VDD, V2, V3 and V5 to each SEG terminal S1-S40. When the output level is at VDD, V1 or V2 level,
0.1 mA is flown out, while 0.1 mA flow in when the output level is at V3, V4, or V5 level. This occurs when 5V
is input to VDD, V1 and V3 or to V2, V4, and V5 respectively.
