Transistor output opto-emulators
Drop-in replacement for traditional optocouplers. Our opto-emulators include diode-emulator inputs and transistor outputs that transmit analog data in applications such as power supply feedback loops.
High-speed logic-output opto-emulators
Pin-compatible and drop-in replaceable for many traditional optocouplers. Our opto-emulators include diode-emulator inputs and digital outputs and can transmit data rate up to 25 Mbps.
Isolated gate drive opto-emulators
Our opto-emulated gate drivers support higher noise immunity, improved part timing skews and are pin-for-pin compatible drop-in replacements for traditional optocoupler gate drivers.

Upgrade your optocouplers to opto-emulators
Pin-to-pin packages
Simplify your design-in process with a high-performing pin-to-pin alternative to existing optocouplers, available in industry-standard packages.
No aging effects
Eliminate the need to compensate for optocoupler aging. Because opto-emulators do not have aging effects or temperature variations to account for, the emulated diode input stage consumes less power.
Reliable isolation
Protect your design and signal integrity with isolation ratings as high as 3,750 VRMS, surge capability up to 10 kV and minimum common-mode transient immunity of ±85 kV/µs.
Understanding isolation technology
Address your isolation challenges with our reliable and affordable isolation technology. Through our proprietary isolation techniques, you can exceed isolation standards without compromising performance.
