NTE1754 & NTE1754S
Integrated Circuit
Vertical Deflection Output Circuit
Description:
The NTE1754 and NTE1754S are full−performance vertical deflection output circuits intended for direct drive of the deflection coils and can be used for a wide range of 90° and 110° deflection systems.
These devices are provided with a guard circuit which blanks the picture tube screen in the absence
of deflection current.
