Note 4: Power supply sequence
At power-on, power should be supplied to the power supply pins according to the following sequence:
1. Pin 31 (I
2L VDD)
2. Pin 45 (DEF/DAC VCC)
3. Pins 16 and 75 (YC VCC/RGB VCC)
Supply power to pin 37 via zener diode through resistor from pin 45. (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 37) became undefined, horizontal transistor may be damaged. When the TA1360F is used for CRT,
control horizontal oscillation frequency by pins 41 and 55.
