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.
