/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 2.2A

The NTE7085 can be used in conjunction with the NTE1863 (NTSC) to provide all the functions re­quired for color TV signal processing.
