Communication interface chip UART485/232

RS-485/RS-422 Transceiver

The SE721A chip is a single-chip transceiver that meets the instrument bus standard (EN1434-3). The internal interface circuit can adapt to the different levels between the master and slave in the instrument bus structure. The connection to the bus is non-polar and supports the use of optical Fully galvanic isolation between the coupling and the slave
