Are there ESD-hardened type isolators housed in small package such as QSOP?
How about ADuM744x?
I know about AN-793.
Our customer had ESD problem with ADUM14xx before, and used it with 200ohm on VDD line.
Does ADuM744x need same way for enhanced system-level ESD performance?
Speaking of 4ch, are only ADuM340x and ADuM440x ESD-hardened type ?
