Note 1:
Applied to the voltage drop occurring between any of the V
DD, V1, V4 and V5 pins and any of the
common pins (COM
1 to COM17) when the current of 4 A flows in or flows out at one common
pin.
Also applied to the voltage drop occurring between any of the V
DD, V2, V3A (V3B) and V5 pins and
any of the segment pins (SEG
1 to SEG120) when the current of 4 A flows in or flows out at one
common pin.
The current of 4
A flows out when the output level is V
DD or flows in when the output level is
V
5.
Note 2:
Applied to the current flowing into the V
DD pin when the external clock (fOSC2 = fin = 270 kHz) is
fed to the internal R
