TV Video Processor
Description:
The NTE1845 is a small–sized multifunctional IC containing the “video, chroma, deflection” circuit of
NTSC color TV in a shrink type 30–Lead DIP package. Besides being small–sized, it has such fea-
tures as greately reduced number of parts and fewer adjustments required. The device contains a
peak clip circuit and is well suited for use in small–sized sets.
