The ISOM811x devices are single-channel optocoupler-emulators with diode-emulator input and transistor output. The devices are pin-compatible and drop-in replaceable for many traditional optocouplers, allowing enhancement to existing systems with no PCB redesign.
ISOM811x opto-emulators offer significant reliability and performance advantages compared to optocouplers, including high bandwidth, low turn-off delay, low power consumption, wider temperature ranges, and tight CTR and process controls resulting in small part-to-part skew. Since there is no aging effect or temperature variation to compensate for, the emulated diode-input stage consumes less power than optocouplers.
ISOM811x devices are offered in a small SOIC-4 packages with 2.54 mm and 1.27 mm pin pitch, supporting a 3.75-kV RMS isolation rating and DC (ISOM811[0-3]) and bi-directional DC (ISOM811[5-8]) input. The high performance and reliability of ISOM811x enable these devices to be used in power supply feedback design, motor drives, I/O modules in industrial controllers, factory automation applications, and more.
