Dear All, I am using HSD ISO8200BQ in our digital output card. When we give logic high the output os HSD is as expected. When we give logic 0 the expected result should be <= 1V but we are getting 2.014V. So kindly suggest me the solution.

The ISO8200BQ is a "galvanic isolated octal high-side smart power solid state-relay", where High-Side means that the output can only be driven to VCC, i.e. the supply rail. There is a built-in pull-down resistor, typically 210 kOhms, which allows some protection functions but is not strong enough to drive the output really low. So all in all it is not a push-pull driver.

Usually this device is used to switch loads which are connected to ground, such as relays etc.

Does it answer your question?
