NTE NTE1797 Datasheet
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.
