NOTES:
13. Dissipation rating assumes device is mounted with all leads soldered to printed circuit board.
2. Back plane drive is in phase with segment drive for 'off' segment, 180 degrees out of phase for 'on' segment. Frequency is 20
times conversion rate. Average DC component is less than 50mV
3. Not tested, Quaranteed by design.
