DESCRIPTION

The STV8211 is a monolithic integrated circuit in

DIP20 package 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 carrier. Used with

TEA2037A (H/V deflection circuit), this IC permits

a complete low-cost solution for black and white

applications.

This is advance information on a new product now in development or undergoing evaluation. Details are subject to change without no tice.
