The LA78045 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 LA78045 to a Sanyo LA768X series or LA769XX series bus control
system signal-processing IC.
• Built-in pump-up circuit for low power dissipation.
• Vertical output circuit.
• Thermal protection circuit.
Parameter
Any and all SANYO Semiconductor products described or contained herein do not have specifications
that can handle applications that require extremely high levels of reliability, such as life-support systems,
aircraft's control systems, or other applications whose failure can be reasonably expected to result in
serious physical and/or material damage. Consult with your SANYO Semiconductor representative
nearest you before using any SANYO Semiconductor products described or contained herein in such
applications.
SANYO Semiconductor assumes no responsibility for equipment failures that result from using products
at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition
ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor
products described or contained herein.
