Product details

Active production, 250 kbps full-duplex RS-485 transceiver in 14-PDIP

The MAX489ECPD+ is a full-duplex RS-422/RS-485 transceiver from Analog Devices, rated for 250 kbps data rate over a single 5V supply rail (4.75V to 5.25V).

5V supply and 70 mV hysteresis — fit for industrial RS-485 buses

Operating from 4.75V to 5.25V, the MAX489ECPD+ drops directly into legacy 5V RS-485 networks without a level shifter. The 70 mV receiver hysteresis filters noise on differential pairs up to 250 kbps — sufficient for most PLC-to-sensor links and building-automation backplanes.

Active lifecycle — no EOL notice on record

No successor or last-time-buy date has been issued. For BOM planning, the part is sourced per RFQ through our supply channel; confirm current lead time at quote.

Frequently asked questions

What is the maximum data rate of MAX489ECPD+?

The MAX489ECPD+ is rated for 250 kbps data rate over RS-422 or RS-485 links.

Is MAX489ECPD+ compatible with 5V RS485 systems?

Yes, the supply range is 4.75V to 5.25V, making it a direct fit for standard 5V RS-485 buses.

What is the difference between MAX489ECPD+ and MAX490ECPD+?

The MAX490ECPD+ is a pin-compatible sibling with a higher data rate (typically 10 Mbps vs 250 kbps). Both are full-duplex, 5V, 14-PDIP transceivers; the MAX489 is optimised for lower-speed, longer-cable applications where slew-rate limiting reduces EMI.

Can MAX489ECPD+ be used in a half-duplex system?

The MAX489ECPD+ is a full-duplex transceiver with separate driver and receiver I/O. It can be wired for half-duplex operation by connecting the driver outputs and receiver inputs to the same differential pair and using an enable signal, but a dedicated half-duplex transceiver (e.g., MAX485) may simplify the BOM.
