RS-485/RS-422 transceiver for 3.3 V industrial buses
The MAX3430CSA+: It supports half-duplex communication at data rates up to 250 kbps — the typical ceiling for multi-drop sensor networks and PLC backplanes where cable lengths exceed 100 metres. The 25 mV receiver hysteresis filters out noise on long twisted-pair runs, reducing false edges on the bus without external filtering. The 1/1 driver/receiver count suits point-to-point or single-master multi-drop topologies.
Analog Devices lists the MAX3430CSA+ as Active and ROHS3 compliant.
