    Hi Jyothi,

    Thanks for following up.

    The price and availability of the parts are up to date on TI website and are regularly updated to reflect their current state. Due to large semiconductor demand, many of our devices get sold as soon as they become available. I would recommend you subscribe to the part notifications by clicking on "Notify me when available" button on respective product page ordering section. By doing so, you will be notified as soon as the parts become available.

    ISOW1412 was launched to TI website in 2020 and ISOW1432 in 2021. Both are in production and have been shipping to customers for a while. We didn't see any customers any issues in meeting any safety and regulatory conformance issues.

    If you are looking for the component level certifications of these devices, then please refer to the respective product page technical documentation section to download the certificates. Please find below direct links to the technical documentation section of the product pages, thanks.
