NTE1797 Integrated Circuit Color TV Vertical Output Circuit Description: The NTE1797 is a monolithic linear IC designed for large–aperture color TV vertical deflection output and has such features as greatly reduced number of external parts and low power dissipation. The NTE1797 can be used in conjunction with the NTE1845 for video chroma deflection use and the NTE1538 for deflection use.
