3 Description

The ISOM811x devices are single-channel optocoupler-emulators with LED-emulator input and transistor output. The devices are pin-compatible and drop-in replacements 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 LED input stage consumes less power than optocouplers.

ISOM811x devices are offered in small SOIC-4 packages with 2.54-mm and 1.27-mm pin pitchs, supporting a 3.75-kVRMS isolation rating and DC (ISOM811[0-3]) and bi-directional DC (ISOM811[5-8]) input options. The high performance and reliability of ISOM811x enables these devices to be used in power supply feedback design, motor drives, I/O modules in industrial controllers, factory automation applications, and more.
