The ISOM8600 is a single-channel isolated switch with diode-emulator inputs which control an output stage with back-to-back MOSFETs. The devices use robust on-off keying modulation to transmit data across the isolation barrier. Since an isolation barrier separates the two sides of these devices, each side can be sourced independently with voltages and currents within recommended operating conditions. The ISOM8600 is designed to be implemented in a variety of applications like realizing switchable termination in communication lines like CAN and RS485, switching burden resistors in analog input modules and small footprint sink/source capable digital output module in AC Servo motor drives.

The opto-emulators do not conform to any specific interface standard and are intended for isolated switching operations. The ISOM8600 is typically placed between a data controller (that is, an MCU or FPGA), and a sensor or a line transceiver, regardless of the interface type or standard.
