FUNCTIONAL DESCRIPTION
THE BLOCK DIAGRAM IS SHOW IN FIGURE 1. BRIGHTNESS OF DISPLAYS ARE DETERMINED BY THE
OUTPUT SINK CURRENT. TO PREVENT OSCILLATIONS, A 1nF CAPACITOR SHOULD BE CONNECTED TO
THE PIN OF BRIGHTNESS CONTROL.
FIGURE 2 SHOWS THE INPUT DATA FORMAT.
FIGURE 3 SHOWS THE TIMING RELATIONSHIPS BETWEEN DATA, CLOCK AND DATA ENABLE.
