DESCRIPTION

The STV8211is a monolithic integrated circuit in DIP20package for black &white television receiv-ers using PNP tuners.It is intended to operate with a negatively modulated vision carrier and fre-quency modulated sound https://www.wendangku.net/doc/124051172.html,ed with TEA2037A (H/V deflection circuit),this IC permits a complete low-cost solution for black and white applications.
