The ISOM871x devices are single-channel opto-emulators with diode-emulator inputs and digital outputs. The devices are pin-compatible and drop-in replaceable for many traditional optocouplers, allowing enhancement to industry-standard packages with no PCB redesign. These devices can transmit data rates up to 25 Mbps and can output 3.3-V and 5-V signals with two logic-output options: CMOS-compatible ouput (ISOM8710) and open-collector output (ISOM8711).
ISOM871x opto-emulators offer significant reliability and performance advantages compared to optocouplers, including high common mode transient immunity (CMTI), low propagation delay, small pulse width distortion (PWD), low power consumption, wider temperature ranges, and tight process controls resulting in small part-to-part skew. Since there is no aging effect to compensate for, the emulated diode-input stage consumes less power than optocouplers. ISOM871x devices are offered in a small SOIC-5 package, supporting a 3.75-kV RMS isolation rating. Its high performance and reliability enable its use in motor drives, I/O modules in industrial controllers, factory automation applications, and more.
