DC input, transistor output, single channel, opto-emulator with 150% to 230% CTR

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 pitches, supporting

3750VRMS and 5000VRMS isolation

ratings with 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.
