3 Description

The ISOM871x devices are single-channel optoemulators

with diode-emulator inputs and digital

outputs. The devices are pin-compatible and dropin

replaceable 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 to compensate for, the emulated diodeinput

stage consumes less power than optocouplers.

ISOM871x devices are offered in a small SOIC-5

package, supporting a 3.75-kVRMS isolation rating.

Its high performance and reliability enable its use

in motor drives, I/O modules in industrial controllers,

factory automation applications, and more.
