Integrated Circuit
Vertical Deflection Output Circuit
w/Drive Circuit for Monitor
Description:
The NTE7085 is an integrated circuit in a 13–Lead SIP type package that contains a vertical deflection
output circuit with a driver for color, B/W TV sets, monitors, and display units with a large aperture
(maximum current 2.2AP–P).
The NTE7085 can be used in conjunction with the NTE1863 (NTSC) to provide all the functions required for color TV signal processing.
