Hi Expert :

                 may I know what's different betwenn ISO1540 and ISO1541 ?

                 According to website description, only din V VDE 0884-10 working voltage (vpk) value is different.

                 what is this value main function ?

May I know what's different between ISO1540 and ISO 1541 ?

    Hi Dustin,

    Thank you for your interest in ISO154x family of devices.
    I am sorry the difference in the values of working voltage for ISO1540 and ISO1541 seems to be a typo, both the devices have the same isolation specs. I will recheck this and confirm you.

    The primary difference between ISO1540 and ISO1541 is that, the former is a device with 2 bidirectional channels (SDA & SCL) while the latter has one bidirectional channel (SDA) and one unidirectional channel (SCL) as shown in Section 5 of ISO154x datasheet titled "Pin Configuration and Functions" on pages 4 and 5.

    I hope that answers your question, thank you.
