Product details

RS422/RS485 full-duplex transceiver in a 24-pin DIP

The MAX1490BEPG+ is a single-channel full-duplex transceiver supporting both RS422 and RS485 protocols at 250 kbps — the data rate ceiling for a 24-pin DIP part that still sees use in retrofit and low-speed industrial links.

Housed in a 24-DIP (0.600-inch, 15.24 mm) through-hole package, the MAX1490BEPG+ mounts directly into a standard 24-pin DIP socket or solders into a plated-through-hole PCB — the 0.100-inch pitch matches legacy backplane and industrial controller layouts. The supplier device package is 24-PDIP, and the part ships in tube packaging.

It is ROHS3 compliant, so it passes the EU RoHS directive without exemption issues.

Frequently asked questions

How can I order the MAX1490BEPG+ or check availability?

The MAX1490BEPG+ is an active-production part. Submit an RFQ for a firm lead-time and price.

Can the MAX1490BEPG+ be used for both RS422 and RS485?

Yes — the MAX1490BEPG+ supports both RS422 and RS485 protocols. It is a full-duplex transceiver with one driver and one receiver, so it handles point-to-point RS422 links and RS485 multi-drop networks within the same part number.

Is the MAX1490BEPG+ compatible with 3.3V logic?

There is no 3.3 V logic compatibility on this part; a level translator would be needed to interface with a 3.3 V controller.
