3 Description

The ISOM811x-Q1 devices are single-channel

optocoupler-emulators with LED-emulator input and

transistor output. The devices are footprint compatible

and pin-to-pin upgrades for many traditional

optocouplers, allowing enhancement to existing

systems with no PCB redesign.

ISOM811x-Q1 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-Q1 devices are offered in small SOIC-4

packages with 2.54mm and 1.27mm pin pitchs,

supporting a 3.75kVRMS isolation rating and DC

(ISOM811[0-3]) and bidirectional DC (ISOM811[5-8])

input options. The high performance and reliability

of ISOM811x-Q1 enables these devices to be used

in power supply feedback design, motor drives, I/O

modules in industrial controllers, factory automation

applications, and more.
