Note 1:
Applied to the voltage drop occurring between any of the VDD, V1, V4 and V5 pins and any of the
common pins (COM1 to COM17) when the current of 4 µA 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
any of the segment pins (SEG1 to SEG100) when the current of 4 µA flows in or flows out at one
common pin.
The current of 4 µA 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,
V1, V2, V3A (V3B) and V4: Open
E, SSR, CSR, and BE: “L” (fixed)
Other input pins: “L” or “H” (fixed)
Other output pins: No load
