Si838x Data Sheet
Bipolar Digital Field Inputs for PLCs and Industrial I/O Modules
The Si838x provides eight input channels ideal for 24 V digital logic commonly used
for industrial applications. These channels can either sink or source current and feature
integrated safety rated isolation. In combination with a few external components, this
provides compliance 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 compliance. These products utilize Silicon Labs' proprietary CMOS-based isolation
technology, supporting up to 2.5 kVRMS withstand voltage. This technology enables high
CMTI (up to 300 kV/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 compared 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 noise immunity, reduced design complexity
and cost. Cascading a total of 128 channels (16x Si838x) with a single MCU interface is
possible with the Si8380S serial output option. The Si8380S also unlocks the ability to
configure each channel with unique filtering behavior.

Note:
1. Low-pass debounce filter delay applies to low-speed channels only.
2. All low-speed channels have a built-in 4 µs low-pass debounce filter delay, in addition to the low-pass filter delay listed in this
table. See 3.6 Debounce Filter for details of the low-pass debounce filter operation.
3. All packages are RoHS-compliant with peak reflow temperatures of 260 °C according to the JEDEC industry standard classifica-
tions and peak solder temperatures.
4. Additional filter and channel configurations available upon request. Contact Silicon Labs for more information.
5. “Si” and “SI” are used interchangeably.
6. An "R" at the end of the Ordering Part Number indicates tape and reel option.
