The NTE1839 and NTE1856 are small鈥搒ized multifunctional integrated circuits containing the 鈥渧ideo,
chroma, deflection鈥?circuit of NTSC color TVs in a 30鈥揕ead DIP type package. Besides being small鈥?/div>
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 鈥淰IFSIF鈥?use or the
NTE1773/NTE1797 for 鈥渧ertical output鈥?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鈥搒ized
TV sets while the NTE1838 contains no peak clip circuit and is suited for large鈥搒ized TV sets.
