Opto-emulators

Upgrade your optocouplers and improve reliability with an opto-emulator

parametric-filterView all products
Opto-emulators are a pin-to-pin alternative to optocouplers, offering improved reliability and signal integrity for isolated systems across industrial applications. With TI's opto-emulators, you get the best of both worlds: the simplicity of drop-in replacements with wider operating temperature ranges, higher common mode transient immunity and longer lifetimes.

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.
