NTE1754
Integrated Circuit
Vertical Deflection Output Circuit
Description:
The NTE1754 is a full鈥損erformance vertical deflection output circuit in a 9鈥揕ead SIP type package
intended for direct drive of the deflection coils and it can be used for a wide range of 90擄 and 110擄
deflection systems.
The NTE1754 is provided with a guard circuit which blanks the picture tube screen in case of absence
of the deflection current.
