Product details

RS-485/RS-422 transceiver for 3.3V industrial networks

The Analog Devices MAX3486CSA+ is a half-duplex transceiver delivering 2.5 Mbps data rate over a single differential pair. It integrates one driver and one receiver in an 8-SOIC package, operating from a 3V to 3.6V supply. The 50 mV receiver hysteresis provides noise margin on cable runs typical of factory-floor serial links. This is a commercial-temperature-grade part rated 0°C to 70°C, suited for indoor control panels, PLC communication ports, and instrumentation backplanes.

Package and mounting

Housed in an 8-SOIC (3.90 mm width) surface-mount package, it fits standard pick-and-place assembly. The narrow SOIC footprint is common across the MAX348x family, simplifying board layout if a drop-in alternate is qualified later.

Lifecycle and sourcing posture

ROHS3 compliant.

Frequently asked questions

What is the difference between the MAX3486CSA+ and the MAX3485?

The MAX3486CSA+ operates from a 3V to 3.6V supply and delivers 2.5 Mbps data rate, while the MAX3485 is a 5V supply part with a higher data rate. The supply voltage is the primary difference — the MAX3486 is the 3.3V version of the same basic transceiver architecture. Both are half-duplex, 1/1 driver/receiver, and pin-compatible in the 8-SOIC package.

Can the MAX3486CSA+ replace the MAX3485?

Yes, the MAX3486CSA+ is pin-compatible with the MAX3485 in the 8-SOIC footprint, but the supply voltage differs. The MAX3486 runs on 3.3V, while the MAX3485 requires 5V. If your board is designed for 5V, the MAX3486 will not work without a supply change. For 3.3V designs, it is a direct drop-in replacement.
