The Vertical Deflection Output IC for TVs and CRT displays
Package 220-7H Type
LA78040B overview
The LA78040B is a The Vertical Deflection Output IC for TVs and CRT displays made by Sanyo, supplied in a 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 LA78040B pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The LA78040B is a vertical deflection output IC for TVs and CRT displays with excellent image quality that use a BUS control system signal processing IC. This IC can drive the direct (even including a DC component) deflection yoke with the saw tooth wave output from the BUS control system signal processing IC.
