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 4mA 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 4mA flows

in or flows out at one common pin.

The current of 4mA 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 = 5V

GND = V5 = 0V,

V1, V2, V3A (V3B) and V4: Open

E, SSR, CSR, and BEB: “L” (fixed)

Other input pins: “L” or “H” (fixed)

Other output pins: No load

The wire between OSC1 and Rf and the wire between

OSC2 and Rf should be as short as possible.

Keep OSCR open.

The wire between OSC2 and OSCR should be as short

as possible. Keep OSC1 open.
