Product details

Active production — 20 Mbps full-duplex RS485/RS422 transceiver

The MAX13450EAUD+ is an active-production full-duplex RS485/RS422 transceiver from Analog Devices, rated for 20 Mbps data rate with a single driver and single receiver on a 14-TSSOP-EP package.

Receiver hysteresis and noise margin

Receiver hysteresis is specified at 15 mV typical — this sets the noise rejection floor on the differential bus. In a noisy factory-floor RS485 run, the 15 mV hysteresis prevents output chatter when the differential signal sits near the switching threshold.

Package and thermal pad — layout note

The 14-TSSOP-EP (exposed pad) package requires a thermal land on the PCB to achieve the datasheet thermal resistance.

Frequently asked questions

What is the data rate of MAX13450EAUD+?

The transceiver is rated for 20 Mbps. At this speed, the bus cable length must be kept short — typically under a few metres — to stay within the signal rise-time budget and avoid reflections.
