NTE1773
Integrated Circuit
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.
