It targets applications such as sound cards, players, and recorders where a clean, programmable switch-matrix scan and audible feedback are needed without loading the host MCU. ## Lifecycle and compliance Marked as Active in production. Note that the part is listed as RoHS non-compliant — verify local regulatory requirements before specifying.","metaTitle":"MAX7349AEG Switch and Sounder Controller, I²C, 24-SSOP","metaDescription":"MAX7349AEG switch and sounder controller with I²C interface, 2.4V–3.6V supply.
