Description
The ST4E1650 is a low-power differential line transceiver for data transmission standard RS485 applications in half-duplex mode, compatible with either 3.3 V or 5 V rail power supplies, fully operating from 3 V to 5.5 V.
The ST4E1650 operates up to 50Mbps. It is ideal for multi-point applications over extended cable runs. It is robust to ESD transients. In particular, the bus pins support ±16kV IEC 61000-4-2 contact discharge. It features robust hot-swap capability during switching on and off, or during plug-in.
It is available in standard SO8 and DFN8 packages and operates from -40°C up to 125°C depending on the package.
