NTE1838 & NTE1856 Integrated Circuit Color TV Video/Chroma/Deflection Circuit
Description: The NTE1839 and NTE1856 are small-sized multifunctional integrated circuits containing the "video, chroma, deflection" circuit of NTSC color TVs in a 30-Lead DIP type package. Besides being small- sized, they have such features as fewer external components and fewer adjustments. required. The NTE1838/NTE1856 can be used in conjunction with the NTE1728 for "VIFSIF" use or the NTE1773/NTE1797 for "vertical output" use to perform all color TV signal processings. The NTE1856 contains a peak clip circuit in the video circuit making it well suited for use in small-sized TV sets while the NTE1838 contains no peak clip circuit and is suited for large-sized TV sets.
