Half-duplex RS-485/RS-422 link in an 8-pin SOIC
The MAX13444EASA+ is a single-channel half-duplex transceiver supporting both RS-485 and RS-422 protocols at 250 kbps — the data rate ceiling for a multi-drop bus running over twisted-pair cable in industrial and building-automation networks. The 25 mV receiver hysteresis filters out noise on long cable runs where common-mode shifts are the dominant signal-integrity risk.
Analog Devices lists the MAX13444EASA+ as Active with ROHS3 compliance.
8-SOIC footprint and supply rails
Supplied in tube; reel quantities available on request. Single 5 V supply (±5 %) simplifies power-tree design — no separate I/O or analog rails. The 250 kbps data rate is a bus-speed ceiling, not a toggle-rate floor; the part also operates correctly at lower baud rates down to DC.
