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.
