MAX3486CSA-T

The MAX3486CSA-T from Analog Devices is a 3.3V, low-power transceiver designed for RS-485 and RS-422 communication. This device integrates one driver and one receiver, supporting half-duplex communication. It features slew-rate-limited drivers that minimize EMI and reduce reflections, enabling error-free data transmission at data rates up to 2.5Mbps.

Key electrical characteristics include operation from a single 3.3V supply, interoperability with +5V logic, and a -7V to +12V common-mode input voltage range. The transceiver is protected against excessive power dissipation by thermal shutdown circuitry and includes current-limiting for driver overload protection. The receiver input features a fail-safe mechanism that guarantees a logic-high output if both inputs are open circuit.

Packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with a surface mount type, the MAX3486CSA-T is suitable for applications requiring robust serial communication. Its design is optimized for EMI-sensitive applications, telecommunications, and industrial-control local area networks.

This transceiver allows up to 32 transceivers on the bus and operates within a temperature range of 0°C to 70°C. It also includes a low-current shutdown mode, consuming only 2nA.
