NTE1485
Integrated Circuit
Vertical Deflection Output Circuit
Features:
D Low power consumption, direct deflection coil driving capability (Flyback voltage two times as
high as supply voltage is supplied during flyback period only)
D High breakdown voltageL 60V
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
