Product overview
Description
The ST4E1651 is a low-power differential line transceiver for data transmission standard RS485 applications in half-duplex mode, compatible with 3.3 V rail power supplies, fully operating from 3 V to 3.6 V.
The ST4E1651 operates up to 50 Mbps. It is ideal for multi-point applications over extended cable runs. It is robust to ESD transients. In particular, the bus pins support ±16 kV 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 a standard SO8 package and operates from -40 °C up to 125 °C.
