*1 Applicable to the voltage drop (VC) occurring in pins VDD, V1, V4, and V5 to each COMMON

pin (COM1 to COM16) when 50 mA flows in or out of all COM and SEG pins. Also applicable

to voltage drop (VS) occurring in pins VDD, V2, V3, and V5 to each SEG pin (SEG1 to SEG40).

When output level is at VDD, V1 or V2 level, 50 mA flows out, while 50 mA flows in when the

output level is at V3, V4 or V5 level.

This occurs when +5V is input to VDD, V1, and V2, and when –3V is input to V3, V4, and V5.
