DIP20 (Plastic Package)
DESCRIPTION The STV8211 is a monolithic integrated circuit in DIP20 package for black & white television receivers using PNP tuners. It is intended to operate with a negatively modulated vision carrier and frequency modulated sound carrier. Used with TEA2037A (H/V deflection circuit), this IC permits a complete low-cost solution for black and white applications. PIN CONNECTIONS
