ISO1540 - Reinforce isolation

Other Parts Discussed in Thread: ISO1540

Hi all,

Would you mind if we ask ISO1540?

ISO1540 is not the reinforced isolation product.
With using ISO78XX series, is it possible to satisfied with the same function as ISO1540(I2C Bidirectional level shifter)?

Kind regards,

Hirotaka-san,

You right the ISO1540 is not reinforced isolation product. If you can tell me what datarates you are interested I can try to suggest some work around with ISO78xx.

Thank you for your prompt reply.
Our customer will use I2C, so the datarate will be 400kHz.

We need your help.

Kind regards,
