It provides four receiver channels with no integrated drivers (0/4 configuration), targeting multi-drop bus interfaces where only receive-side termination is needed. ## Receiver hysteresis and bus margin The 230 mV receiver hysteresis sets the noise margin between logic thresholds — on a long RS-485 stub with ground-potential shifts or cable reflections, this hysteresis prevents the output from chattering on a slowly rising differential signal. The 35 Mbps data rate supports high-speed polling cycles on a factory-floor fieldbus segment without bit-error accumulation. ## Supply rail and temperature grade Operating from a single 4.5V to 5.5V rail, the receiver draws its bias from the same 5V supply that powers the bus transceiver side. ## Package and board integration Surface-mount assembly with the exposed pad soldered to the PCB copper is assumed in the thermal design.","metaTitle":"MAX14891EATP+T RS-422/RS-485 Receiver, 35 Mbps, 20-TQFN","metaDescription":"Active production RS-422/RS-485 receiver IC from Analog Devices. 4.5-5.5V supply, 230 mV hysteresis, -40°C to +125°C. 0/4 drivers/receivers.
