The IS281B optocoupler from Isocom Components 2004 LTD is designed for reliable high speed optically isolated signal transfer. This device is a 4-pin surface-mount device (SMD) that uses a transistor photovoltaic output. It features long-term stability and low off-state leakage current for temperature sensitivity. Its high current transfer ratio makes it ideal for a wide range of applications. It is ideal for digital logic and signal interfacing, motion control and instrumentation and industrial control systems. It also helps minimize power consumption and noise in these systems. With its high isolation resistance of 1000MΩmin, it is well-suited to help protect sensitive circuits from inductive and catalytic interference. This is an ideal product for reliable signal transfer and interfacing in a wide variety of applications.
