The Sanyo LA78141 is an integrated circuit (IC) designed for use in television sets and other video applications. It is a vertical deflection output IC that controls the vertical scanning of the display screen. The device can drive a large deflection coil with a high output current, making it ideal for use in larger displays. Additionally, it has built-in thermal protection and over-current protection, ensuring safe and reliable operation.

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.
