NTE NTE1771

NTE1771
Integrated Circuit
TV Video Processor
Description:
The NTE1771 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 features as greately reduced number of parts and fewer adjustments required. The device contains no
peak clip circuit and is well suited for use in large–sized sets.
