CHARACTERISTICS
All voltages are measured in test circuit of Fig.9 with respect to GND (pin 9); V
amplitudes (black-to-white) at output pins 24, 22 and 20; nominal settings of brightness, contrast, saturation and white
level control; without beam current or peak drive limiting; unless otherwise specified.
