The MAX485ESA is a low-power transceiver designed for RS-485 and RS-422 communication applications. It integrates one driver and one receiver, operating from a single 5V supply. This device supports high-speed data transmission up to 2.5Mbps, making it suitable for various industrial and control networks.
Key features include drivers protected by short-circuit current limiting and thermal shutdown circuitry. The receiver input incorporates a fail-safe feature that ensures a logic-high output when the input is open-circuited. These transceivers draw minimal supply current, between 120µA and 500µA when unloaded or fully loaded with disabled drivers.
The MAX485ESA is available in an 8-SOIC package and is designed for surface mount applications. It is well-suited for applications requiring reliable communication in electrically noisy environments, such as industrial control local area networks and EMI-sensitive systems.

The driver slew rates of the MAX485ESA are not limited, allowing them to transmit up to 2.5Mbps.
All parts operate from a single 5V supply.
These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers.
Additionally, the MAX481, MAX483, and MAX487 have a low-current shutdown mode in which they consume only 0.1µA.
Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state.
The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.
The MAX481, MAX483, MAX485, MAX487, and MAX1487 are designed for half-duplex applications.
