3 Description

The ISOM871x devices are single-channel optoemulators

with diode-emulator inputs and digital

outputs. The devices are pin-compatible and drop-in

replacable for many traditional optocouplers, allowing

enhancement to industry-standard packages with no

PCB redesign. These devices can transmit data

rates up to 25 Mbps and can output 3.3-V and

5-V signals with two logic-output options: CMOScompatible

ouput (ISOM8710) and open-collector

output (ISOM8711).

ISOM871x opto-emulators offer significant reliability

and performance advantanges compared to

optocouplers, including high common mode transient

immunity (CMTI), low propagation delay, small pulse

width distortion (PWD), low power consumption,

wider temperature ranges, 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 diode-input stage consumes less

power than optocouplers. ISOM871x devices are

offered in a small SOIC-5 package, supporting a 3.75-

kVRMS reinforced isolation rating. Its high performance

and reliability enable its use in motor drives, I/O

modules in industrial controllers, factory automation

applications, and more.
