Product details

The through-hole 8-DIP (0.300-inch, 7.62 mm pitch) is a field-service dream — no hot air, no reflow oven, just a socket and a pair of pliers. Data rate is 500 kbps, which covers most industrial RS485 bus applications — PLC links, motor drive comms, sensor networks — without the edge-rate headaches of faster transceivers. Supply voltage is 4.75V to 5.25V, a tight 5V rail that rules out 3.3V systems.

Temperature grade — indoor only

That means this part belongs in a control cabinet or office equipment, not an engine bay or rooftop enclosure. If your BOM calls for -40°C operation, you need the industrial-grade sibling.

Lifecycle status is Active. ROHS3 compliant.

Frequently asked questions

Can MAX3084CPA+ be used for RS485 half-duplex?

The part is full-duplex only. For half-duplex RS485 you need a transceiver with a single driver/receiver pair and direction control — this one has separate driver and receiver pins and no enable logic for half-duplex bus sharing.

What is the data rate of MAX3084CPA+?

500 kbps. That's the maximum — practical throughput depends on cable length and termination.
