Notes: 1. Applies to the resistance (R
COM
) between the V1OUT, V2OUT, V5OUT, and V
SS
pins and
the common signal pins (COM1 to COM16), and the resistance (R
SEG
) between the
V1OUT, V3OUT, V4OUT, and V
SS
pins and the segment signal pins (SEG1 to SEG40),
when Id is flowing in the pins.
The voltage applied to V1OUT through V5OUT must not exceed V
CC
.
2. The guaranteed temperature as an electrical characteristic for die type products is
75°C.
