POWER AMPLIFIER FOR DRIVING A DEFLECTION CIRCUIT OF A
COLOR TELEVISION
The TA8432K is a Vertical-Delection-Output circuit IC for
middle and large aperture color televisions.
The TA8432K combines the vertical output circuit and the
Ramp-generator in a 12 leads single-in-line type plastic
package.
The TA8432K requires only vertical deflection negative
pulses for vertical operation.
