Product details

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

The Maxim Integrated MAX3087ESA+ is a single-channel, full-duplex RS-485/RS-422 transceiver in an 8-pin SOIC package. 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

This part runs on a 4.75 V to 5.25 V supply. 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.

Active production — no end-of-life concern

The MAX3087ESA+ is listed as Active in production. ROHS3 compliant. This part is available through independent distribution and can be quoted to order against an RFQ.

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.
