The Maxim Integrated MAX14783EATA+T is a single-channel, half-duplex transceiver supporting RS-485 and RS-422 protocols at data rates up to 42 Mbps. The wide supply range of 3V to 5.5V lets it work on both legacy 5V backplanes and modern 3.3V industrial buses without a separate level shifter. Receiver hysteresis is specified at 10 mV, which helps reject noise on long cable runs typical in factory automation and building control networks.
The MAX14783EATA+T is rated for 42 Mbps, which supports high-speed RS-485 links for encoder feedback, vision system triggers, and multi-drop backplanes where throughput matters more than cable length.
Within the same family, the MAX14783E series shares the same footprint and pinout across speed grades. For a drop-in alternative at a different data rate, check the MAX14783E variants — the package and pin arrangement are consistent, so a BOM swap requires only a speed review, not a board layout change.
