Active RS-485/RS-422 transceiver, 16 Mbps, 3-5.5V supply
The MAX13433EETD+T is an active-production, full-duplex RS-485/RS-422 transceiver from Analog Devices, rated for 16 Mbps signaling with a single 3V to 5.5V supply rail. The 1/1 driver/receiver configuration handles point-to-point or multi-drop bus architectures typical in factory automation, building management, and instrumentation backplanes.
Industrial temperature range and receiver hysteresis
The 15 mV receiver hysteresis provides noise immunity on long cable runs — the minimum differential input voltage threshold is well below the hysteresis band, so a 200 mV bus signal with 50 mV of common-mode noise stays within the valid logic window.
14-TDFN package with exposed pad
Housed in a 14-TDFN (3x3 mm) package with an exposed thermal pad, the MAX13433EETD+T requires a PCB land pattern that connects the pad to a ground plane for heat dissipation. The 0.50 mm pitch and 0.25 mm pad width are standard for this package class — the layout should match the supplier package drawing (14-TDFN) to ensure solder-joint reliability under vibration.
ROHS3 compliance and supply voltage flexibility
ROHS3 compliant, the part is free of the ten restricted substances plus four phthalates.
