Si8384P
feature integrated safety rated isolation. In bination with a few external ponents, this provides pliance to IEC 61131-2 switch types 1, 2, or 3. The input interface is based on Silicon Labs' ground-breaking CMOS based LED emulator technology which enables the bipolar capability (sinking or sourcing inputs) with no VDD required on the field side. The output interface from the Si838x device allows for low power operation with 2.25 V pliance. These products utilize Silicon Labs' proprietary CMOS-based isolation technology, supporting up to 2.5 k VRMS withstand voltage. This technology enables high CMTI (up to 300 k V/μs), lower propagation delays and channel skew, reduced variation with temperature and age, and tighter part-to-part matching. The Si838x offers longer service life and dramatically higher reliability pared to opto-coupled input solutions.
Product options include parallel or serialized outputs. Parallel outputs can be purchased with built-in, low-pass filters for improved...
