ISO7242C-Q1: ISO7242C-Q1

Amod Mujumdar
Prodigy 40 points
Part Number: ISO7242C-Q1
Other Parts Discussed in Thread: ISO7242C, ISO7242M, ISO6742

Hi , 

We are using ISO7242MDW part in our existing design. However we decided to replace former part  with ISO7242CQDWRQ1. I compared parameter and found that both are almost same. Can any body explain in detail what is exactly the difference in these two parts? 

Pl. revert at urgent. We would like to finalize design. 

Thanks,

Amod

    Hi Amod,

    Welcome to TI E2E Forum!
    Thanks for reaching out and for your interest in TI digital isolators.

    ISO7242M is a 150Mbps rated device while ISO7242C is a 25Mbps device. This is the key difference between the two parts and due to the difference in datarate, all the associated datarate dependent parameters are also going to be different. This includes switching characteristics (all timing specifications) and current consumption at higher datarates. Apart from that everything else is going to be similar. If your application datarate is less than 25Mbps, then yes ISO7242C can be used without any issues.

    Please note that ISO7242M and ISO7242C are our old generation parts, for all new designs we recommend customer to choose ISO67xx family of devices. In this case, ISO6742 would be the equivalent device.

    Let me know if you have any further questions, thanks.
