Color TV Vertical Deflection Output Circuit

Description:

The NTE1773 is a monolithic linear integrated circuit designed for small–aperture color TV vertical

deflection output and has such features as greatly reduced number of external parts and low power

dissipation. The NTE1773 can be used in conjunction with the NTE1845 for video chroma deflection

use and the NTE1538 for deflection use.
