Note 4: Power supply sequence
At power-on, power should be supplied to the power supply pins according to the following sequence:
1. Pin 29 (I²L VDD)
2. Pin 19 (DEF/DAC V_CC)
3. Pins 40 and 55 (RGB V_CC/YC V_CC)
Supply power to pin 29 via zener diode through resistor from pin 19. (See “Application Circuit”.)
BUS preset value is become undefined and caused malfunction of the IC unless supplying power to all
supply pins or follow the power supply sequence described above. When the frequency of horizontal output
(pin 26) became undefined, horizontal transistor may be damaged. When the TA1360N is used for CRT,
control horizontal oscillation frequency by pins 13 and 22.
