DESCRIPTION
The 66326 high voltage isolator consists of an 850nm LED optically coupled to a high gain inverting photon detector. The
isolator provides high CTR and low leakage currents over the specified temperature range of -40C to +100C.The isolator is
built with hermetic components internally optically coupled and encased in a high temperature outer PPS plastic housing.
