Notes:
1. I
DD
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. I
DD
Static is the IC current after column data is loaded and not being clocked through the on-board shift register.
3. V
I
represents the input voltage to an input pin.
