MAX3486ESA+

The MAX3486ESA+ from Maxim Integrated is a 3.3V, low-power transceiver suitable for RS-485 and RS-422 communication systems. This device incorporates one driver and one receiver, operating from a single 3.3V supply without the need for a charge pump. Its slew-rate limited drivers are designed to minimize EMI and reduce signal reflections, enabling error-free data transmission at speeds up to 2.5Mbps. The MAX3486ESA+ supports half-duplex communication and is interoperable with +5V logic.

Key features include a low-current shutdown mode drawing only 2nA, a wide -7V to +12V common-mode input voltage range, and protection against driver overload through current-limiting and thermal shutdown circuitry. The receiver input includes a fail-safe feature that ensures a logic-high output when inputs are open circuit. This transceiver allows for up to 32 transceivers on the bus, making it suitable for industrial control local area networks and telecommunications applications.

The MAX3486ESA+ is supplied in an 8-pin SOIC package and is designed for surface mount applications. It operates within a temperature range of -40°C to +85°C.
