CA-IS3721LS High Speed Dual‐Channel Digital Isolators

CA-IS3721LS vs Si8621BB-B-IS / Si8621BC-B-IS

The CA-IS3721LS stands out in comparison to the Si8621BB-B-IS and Si8621BC-B-IS due to its superior isolation voltage and improved noise immunity. While the Si8621BB-B-IS and Si8621BC-B-IS provide 2500V isolation, the CA-IS3721LS offers 5000V isolation, which provides enhanced protection for critical components, especially in high-voltage industrial and automotive applications. Additionally, the CA-IS3721LS is specifically designed to handle higher EMI (electromagnetic interference), which is a key factor in maintaining stable communication in noisy environments. This makes the CA-IS3721LS more reliable in challenging operational conditions.
