Monolithic Linear IC

LA76070
NTSC Color Television IC

Overview
The LA76070 is an NTSC color television IC. In addition to providing IIC bus control based rationalization of IC control and the adjustment manufacturing process associated with the TV tube itself, it also includes all functions actually required in mass-produced television sets. As such, it is anextremely practical bus control IC.
* The LA7840/41 or LA7845N/46N is recommended as the vertical output IC for use with this product.
