Product details

RS-422/RS-485 full-duplex transceiver for industrial serial links

The Maxim Integrated MAX3157CAI+ is a full-duplex transceiver supporting RS-422 and RS-485 protocols at 250 kbps. It integrates one driver and one receiver in a 28-SSOP surface-mount package, operating from a 4.75 V to 5.25 V supply over the 0 °C to 70 °C commercial temperature range. Typical applications include industrial control networks, building automation, and instrumentation where a balanced differential serial link is required.

Frequently asked questions

Is MAX3157CAI+ RoHS compliant?

Yes, the MAX3157CAI+ is ROHS3 compliant.

What is the closest pin-compatible alternative to MAX3157CAI+?

Within the same family, the MAX3157EAI+ is a direct functional equivalent with identical pinout, data rate, and supply range, differing only in extended temperature grade. Qualify the temperature range against your application before substituting.

Can MAX3157CAI+ be used with 3.3V logic?

The supply voltage range is 4.75 V to 5.25 V; the part is not specified for 3.3 V logic levels. For 3.3 V RS-485 applications, consider a transceiver rated for that supply rail.
