Note 1: Applied to the voltage drop occurring between any of the VDD, V1, V4 and V5 pins and any of the
µ
common pins (COM1 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 VDD, V2, V3A (V3B) and V5 pins and
µ
any of the segment pins (SEG1 to SEG100) when the current of 4 A flows in or flows out at one
common pin.
µ
The current of 4 A flows out when the output level is VDD or flows in when the output level is
V5.
Note 2: Applied to the current flowing into the VDD pin when the external clock (fOSC2 = fin = 270 kHz) is
fed to the internal Rf oscillation or OSC1 under the following conditions:
VDD = 5 V
GND = V5 = 0 V,

E, SSR, CSR, and BE: “L” (fixed)
Other input pins: “L” or “H” (fixed)
