Vertical Deflection IC, Vertical Output, Vertical Drive, Pump-up

The LA78141 is a vertical deflection output IC for high image quality TV and CRT displays that supports the use of a bus control system signal-processing IC. The sawtooth waveform from the bus control system signal-processing IC can directly drive the deflection yoke (including the DC component). Color TV vertical deflection system adjustment functions can be controlled over a bus system by connecting the LA78141N to a Sanyo LA768X series or LA769XX series bus control system signal-processing IC.
