In a factory-floor RS485 run with common-mode shifts from motor drives, this hysteresis prevents the receiver from chattering on idle or unterminated lines. The half-duplex topology means the driver and receiver share the same bus pair; the transceiver must be enabled and disabled by the host UART's direction pin. The 250 kbps data rate is typical for Modbus RTU and other polled fieldbus protocols.","metaTitle":"MAX13442EASA+T RS485/RS422 Transceiver, 250kbps, 8-SOIC","metaDescription":"Analog Devices MAX13442EASA+T half-duplex RS485/RS422 transceiver. 250kbps data rate, 4.75-5.25V supply, -40 to +125°C.
