MSP-GANG430: JTAG isolation to attach to GANG programmer?

Part Number:MSP-GANG430

Seeing if anyone is aware of a 3rd party or otherwise that offers isolation of the JTAG signals.

Something similar to the appnote described below:

Ideally would like this to attach to the JTAG signals on the GANG programmer.

Thanks
