Vertical Deflection Output Circuit
Description:
The NTE1754 is a full–performance vertical deflection output circuit in a 9–Lead SIP type package
intended for direct drive of the deflection coils and it can be used for a wide range of 90° and 110°
deflection systems.
The NTE1754 is provided with a guard circuit which blanks the picture tube screen in case of absence
of the deflection current.
Features:
D Direct Drive to the Deflection Coils
D 90°and 110° Deflection System
D Internal Blanking Guard Circuit
D Internal Voltage Stabilizer
Applications:
D Video Monitors
D TV Receivers
