Product details

10 Mbps full-duplex RS-485/422 in an SOIC-8

It handles data rates up to 10 Mbps, making it a fit for high-speed industrial communication links like Profibus or Modbus over twisted-pair cable. The receiver includes 100 mV of hysteresis for noise rejection on long runs, and the driver delivers the differential output levels required by the RS-485 standard.

5V supply only — check your rail

It is not a 3.3 V transceiver. If your board has a 3.3 V bus rail, this part will not work — you need a 3.3 V RS-485 part like the MAX3088E. The supply range is a hard boundary: undervoltage below 4.75 V and the driver output levels may not meet the RS-485 spec.

ROHS3 compliant.

Frequently asked questions

What is the difference between MAX3087ESA+ and MAX3088ESA+?

The MAX3088ESA+ is the 3.3 V supply version of the same transceiver. The MAX3087ESA+ requires a 5V supply (4.75 V to 5.25 V). If your board runs on 3.3 V, the MAX3088ESA+ is the pin-compatible alternative. Both are full-duplex, 10 Mbps, SOIC-8 parts.

Does MAX3087ESA+ work with a 3.3V supply?

No. The supply range is 4.75 V to 5.25 V. A 3.3 V rail will not meet the minimum operating voltage. Use the MAX3088ESA+ for 3.3 V systems.
