/Drive Circuit for Monitor
Description:
The NTE7085 is an integrated circuit in a 13Lead 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
PP
).
The NTE7085 can be used in conjunction with the NTE1863 (NTSC) to provide all the functions re-
quired for color TV signal processing.
