Product details

RS485/RS422 transceiver with 50 Mbps edge rate

The MAX22508EASA+ is a full-duplex RS485/RS422 transceiver from Analog Devices, packing one driver and one receiver into an 8-SOIC package. The 50 Mbps data rate supports high-speed fieldbus links — think Profibus DP or similar differential serial buses — where the edge rate must stay clean across a few metres of twisted pair. The 250 mV receiver hysteresis filters noise on long cable runs, reducing false edges from reflections or coupled interference.

Surface-mount assembly with tube packaging — the tube is the standard SOIC-8 carrier, easy to feed into a pick-and-place feeder or store on the shelf without moisture-barrier bag concerns if the floor life is managed per J-STD-020.

No official second-source or pin-compatible replacement is recorded — the part is the only order code at this spec point in the Analog Devices RS485 portfolio.

Frequently asked questions

Is MAX22508EASA+ compatible with 3.3V logic?

The receiver output and driver input thresholds are referenced to the VCC pin, so at 3.3 V the logic levels are 3.3 V CMOS compatible.

What is the data rate of MAX22508EASA+?

50 Mbps maximum. At this rate the driver output transition time is fast enough for short cable runs (a few metres) at RS485 data rates, but for longer buses the cable attenuation and stub length will limit the practical reach.

What is the pinout of MAX22508EASA+?

The 8-SOIC pinout follows the standard RS485 transceiver assignment: RO (receiver output), RE (receiver enable), DE (driver enable), DI (driver input), GND, A (non-inverting bus), B (inverting bus), and VCC. The exact pin numbering is in the datasheet — the supplier device package is 8-SOIC.
