Notes: 1. Operating over the specified voltage range is guaranteed, except where the supply voltage changes suddenly during

CPU access.

2. For a voltage differential of 0.1V between input (V1, …, V4) and output (COM, SEC) pins. All voltages within specified

operating voltage range.

3.

IZD1520AA and IZD1521AA only. Does not include transient currents due to stray and panel capacitances.

4.

IZD1521OA only. Does not include transient currents due to stray and panel capacitances.
