Product details

20 Mbps RS-485/RS-422 transceiver for industrial links

Data rate is 20 Mbps over a 4.5 V to 5.5 V supply, with 15 mV receiver hysteresis.

This part runs on a 5 V nominal supply (4.5 V to 5.5 V range). It is not a 3.3 V logic-compatible transceiver — if your UART or controller operates at 3.3 V, you will need level translation on the driver input and receiver output pins. The 15 mV receiver hysteresis helps with noise immunity on differential pairs, but the supply rail is the hard constraint for BOM fit.

Frequently asked questions

Is MAX13451EAUD+T compatible with 3.3V logic?

No — the supply range is 4.5 V to 5.5 V, and the logic inputs are referenced to that rail. 3.3 V logic levels will not reliably drive the driver input without a level shifter.
