Notes:
1. IDD Dynamic is the IC current while clocking column data through the on-board shift register at a clock frequency of 5 MHz, the display is not
illuminated.
2. IDD Static is the IC current after column data is loaded and not being clocked through the on-board shift register.
3. VI represents the input voltage to an input pin.
4. Four characters are illuminated with a typical ASCII character composed of 15 dots per character.
5. IC junction temperature TJ (IC) = (PD)(RqJ-PIN + RqPC-A) + TA.
