Product details

RS-485/RS-422 half-duplex transceiver, 250 kbps

The MAX1483ESA+ is a single-channel half-duplex transceiver supporting both RS-485 and RS-422 protocols at a data rate of 250 kbps — the standard ceiling for most building-automation and industrial fieldbus segments where cable length exceeds 100 m.

Receiver hysteresis and noise margin

The 75 mV of receiver hysteresis provides a clean switching threshold on a long stub or unterminated drop — enough to suppress the differential noise that a 250 kbps edge couples onto an unshielded twisted pair in an elevator shaft or HVAC duct.

Frequently asked questions

What is the closest pin-compatible alternative to MAX1483ESA+?

The MAX1483ESA+ shares its pinout and SOIC-8 footprint with the MAX3483ESA+ (3.3 V supply variant) and the industry-standard MAX483/MAX1487 families. For a 5 V-only design, the MAX1483 is the direct functional equivalent; no official second-source cross-reference is published by Analog Devices.
