3 Description

The ISOM811x 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 opto-emulators offer 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.

ISOM811x 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 enables these devices to be used in power

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

industrial controllers, factory automation applications,

and more.
