Description

The D78040 is TV and CRT Display Vertical Output IC with Bus Control Support.

The LA78040 ( = D78040 ) 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 LA78040 to a Sanyo LA768X series or LA769XX series bus control system signal-processing IC.

Since the LA78040 provides a maximum deflection current of 1.8Ap-p, it is optimal for small and medium size CRTs.
