UCC23514: Can it replace LTV-3120

Victoria Qin

Part Number: UCC23514

Hi experts,

Can UCC23514S replace LTV-3120? I don't think so. Just want to double confirm. Thanks! Or do we have p2p recommendation for LTV-3120?

Hi Victoria,

I think it can replace the LTV device. What is the application schematic? Is there an external connection on the PCB between pin 6 and 7?

The UCC23514 is designed to replace optocouplers and offer higher isolation voltages, shorter propagation delays, and longer lifetimes.

Best regards,

Sean

Hi Sean,

Please see the screenshot. Just short the pin 6 and 7. Can 23514S replace it?

Hi Victoria,

Perfect! It looks like the UCC23514S will be a pin-to-pin replacement of the LTV device in this schematic.

Best regards,

Sean
