LA78040 Datasheet – TV and CRT Display Vertical Output IC
LA78040 overview
The LA78040 is a TV and CRT Display Vertical Output IC made by Sanyo, supplied in a TO-220-7H Type package. The absolute maximum ratings table on this page lists the 7 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the LA78040 pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The LA78040 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.
