I have a part I believe to be an I2C isolator, but I am unable to identify it from the IC markings

It is a 14 pin TSSOP and the full top face markings are:

CM077B | 55K G4 | D5PC

Thanks in advance

Hi James,

Welcome to TI E2E Forum!

You can use the tool from below link to find TI product information based on package top markings. I did a quick search and found this part to be CD4077BPW which is a device with quad XNOR gate in TSSOP-14 package.

For I2C isolation, please refer to devices ISO1540 and ISO1541. Thanks.
