Product details

RS-485/422 full-duplex transceiver for 5V industrial buses

The MAX3081ECSA+ is a single full-duplex RS-485/RS-422 transceiver from Analog Devices, delivering 115 kbps on a 4.75V to 5.25V supply rail.

Supply rail and temperature grade — fit check for your BOM

This transceiver operates from a single 5V supply (4.75V–5.25V), so it drops directly into a 5V logic domain without a separate regulator. The 8-SOIC package (0.154-inch body width) is a standard footprint shared by many RS-485 parts, easing PCB layout reuse. ROHS3 compliance means no exemption-based paperwork for EU or RoHS-regulated markets.

Active lifecycle — no last-time-buy pressure

The ROHS3 compliance is current — no transition risk from older lead-bearing finishes.

Frequently asked questions

Can MAX3081ECSA+ be used in 5V systems?

Yes. The supply voltage range is 4.75V to 5.25V, so it operates directly on a nominal 5V rail. The logic inputs are 5V-tolerant; no level shifting is needed when interfacing with a 5V MCU or UART.

What is the difference between MAX3081ECSA+ and MAX3081ECSA?

The '+' suffix typically denotes ROHS3 compliance and lead-free finish on Analog Devices parts. The MAX3081ECSA+ is ROHS3 compliant, while the non-plus version may carry a tin-lead finish. Electrically the two are identical — same data rate, supply range, and temperature grade. For new designs the '+' version is preferred for RoHS markets.
