Product details

RS-485/RS-422 transceiver for 10 Mbps industrial buses

It operates from a 4.75 V to 5.25 V supply and includes 100 mV of receiver hysteresis for noise rejection on long or electrically noisy bus runs.

10 Mbps data rate — bus timing margin for high-throughput links

At 10 Mbps, this transceiver supports PROFIBUS-DP and Modbus RTU at high baud rates. The 100 mV hysteresis filters out noise on unterminated stubs.

Housed in a 14-SOIC (0.154" width, 3.90 mm body) surface-mount package, the MAX3089ESD+T shares the same footprint as the industry-standard SOIC-14. The 14-SOIC supplier device package is the same 14-SOIC, so no footprint mismatch between the order code and the physical part.

Frequently asked questions

What is the maximum data rate of MAX3089ESD+T?

The MAX3089ESD+T is rated for a maximum data rate of 10 Mbps, making it suitable for high-speed RS-485/RS-422 networks such as PROFIBUS-DP and high-baud-rate Modbus.

Does MAX3089ESD+T work with 5V logic?

Yes, the supply voltage range of 4.75 V to 5.25 V is compatible with 5 V logic families. For 3.3 V systems, a level translator is needed on the digital I/O lines.

Does MAX3089ESD+T include receiver hysteresis?

Yes, the receiver includes 100 mV of hysteresis, which improves noise immunity on long or noisy RS-485/RS-422 bus lines.
