Overview
TA8445K TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8445K POWER AMPLIFIER FOR DRIVING A DEFLECTION CIRCUIT OF A COLOR TELEVISION The TA8445K is a power amplifier for driving a deflection circuit of a middle and large screen size color television.
The TA8445K combines the vertical output circuit and the Ramp-generator in a 12-pin shrink DIP plastic package.
The TA8445K requires only vertical deflection positive pulse for vertical operation.
