3 Description

The ISOM8110-EP device is a single-channel optocoupler-emulator with LED-emulator input and transistor output. The device is footprint compatible and pin-to-pin upgrades for many traditional optocouplers, allowing enhancement to existing systems with no PCB redesign.

ISOM8110-EP opto-emulator offers significant reliability and performance advantages compared to optocouplers, including high bandwidth, low turn-off delay, low power consumption, wider temperature ranges, flat CTR, and tight 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.

ISOM8110-EP is offered in a small SOIC-4 package with 2.54mm pin pitch, supporting a 3750VRMS isolation rating. The high performance and reliability of ISOM8110-EP enables the device to be used in power supply feedback design, avionics, defense, and more.
