Notes:

8.

Positive current values refer to the current flowing into device and negative values refer to current flowing out of

pins. Voltages are referenced to ground unless otherwise specified (except

V

9.

The power supply current for both transmitter and receiver can vary with the number of active I/O channels.

10. The 16-grayscale test pattern tests device power consumption for a “typical” LCD display pattern. The test

pattern approximates signal switching needed to produce groups of 16 vertical strips across the display.
