NTE1754 Integrated Circuit Vertical Deflection Output Circuit
Description: The NTE1754 is a fullperformance vertical deflection output circuit in a 9Lead 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.
