Datasheet for the STV8223B, an STMicroelectronics STV-series IC for TV and display equipment, stored as a 113 KB PDF. The B suffix in the name indicates a specific version of the device, which matters when substituting. The document provides pin descriptions, block diagram, electrical limits and a reference application, useful for measuring pin voltages and signals during fault finding on a chassis. Compare the full marking on the fitted chip, including the suffix, with the datasheet before ordering a part.
