Si838x Data Sheet Bipolar Digital Field Inputs for PLCs and Industrial I/O Modules KEY FEATURES 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 Bipolar digital interface with 24 V sinking or sourcing inputs 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 Eight total inputs in one package on Skyworks ground-breaking CMOS based LED emulator technology which enables High data rates of up to 2 Mbps the bipolar capability (sinking or sourcing inputs) with no VDD required on the field Safety rated integrated isolation of 2.5 side. The output interface from the Si838x device allows for low power operation with kV RMS 2.25 V compliance. These products utilize Skyworks proprietary CMOS-based isolation Low input current of 1 mA typ technology, supporting up to 2.5 kV withstand voltage. This technology enables high RMS No VDD required on field side CMTI (up to 300 kV/s), lower propagation delays and channel skew, reduced variation High electromagnetic immunity with temperature and age, and tighter part-to-part matching. The Si838x offers longer Selectable debounce filter times of up to service life and dramatically higher reliability compared to opto-coupled input solutions. 100 ms Product options include parallel or serialized outputs. Parallel outputs can be purchased Configurable debounce filter modes with built-in, low-pass filters for improved noise immunity, reduced design complexity available with SPI interface option and cost. Cascading a total of 128 channels (16x Si838x) with a single MCU interface is Transient immunity up to 300 kV/s possible with the Si8380S serial output option. The Si8380S also unlocks the ability to Flow-through output configuration with configure each channel with unique filtering behavior. eight outputs Option for SPI interface with daisy-chain Applications: Safety Regulatory Approvals: capability Programmable logic controllers UL 1577 recognized Wide 2.25 to 5.5 V VDD operation Industrial data acquisition Up to 2500 V for one minute RMS Wide operating temperature range 40 to +125 C Distributed control systems CSA component notice 5A approval Compliant to IEC 61131-2 CNC machines IEC 60950-1 Type 1, 2, 3 I/O modules IEC 62368-1 RoHS-compliant packages Motion control systems VDE certification conformity QSOP-20 VDE 0884-10 CQC certification approval GB4943.1 Si8380P Si8380S A1 1 20 B1 A1 1 20 MISO e e 2 19 A2 2 19 B2 A2 MOSI e e A3 3 18 B3 A3 3 18 NSS e e 4 17 A4 4 17 B4 A4 SCLK e e COM 5 16 VDD COM 5 16 VDD SPI 15 15 COM 6 GND COM 6 GND 7 14 7 14 A5 B5 A5 MOSI THRU e e A6 8 13 B6 A6 8 13 NC e e 9 12 9 12 A7 B7 A7 NC e e A8 10 11 B8 A8 10 11 NC e e Skyworks Solutions, Inc.
