Multi-Channel PLC Input Isolators Race At Speeds Up To 2 Mb/s
Silicon Labs

Trumpeted as the industry’s first high-speed, multi-channel digital isolators designed to meet the demands of programmable logic controller (PLC) applications, the Si838x PLC field input isolators operate at speeds up to 2 Mb/s with up to eight channels per device. Other features include high noise immunity and 2.5 kVRMS isolation. By daisy chaining 16 Si838x isolators, developers can create PLCs with up to 128 channels supported by a single serial peripheral interface (SPI) port on the system’s embedded processor. The controller interface can be eight parallel channels or a four-port SPI. Samples and production quantities of the Si838x PLC field input isolators are available now in a compact 20-QSOP package. Pricing begins at $1.91 each/10,000. For more details, visit
