The SIT3088ETK is a RoHS compliant, RS-485/RS-422 ICs DFN3*3-8 manufactured by SIT. The ICs support full duplex and multi-mastering communications up to 10 Mbps. It is designed to provide robust EMI/EMC performance with minimal component count for narrowband industrial control systems. The IC has a wide operating temperature range of -40°C to 125°C, low supply current, and low supply voltage. It also has an integrated data rate support up to 1.5 Mbps, up to 32 nodes, and up to 4KV surge immunity. The signal pin is designed for connecting external termination resistors, and the integrated surge immunity can improve signal integrity.
