The MAX483ESA from Maxim Integrated is a low-power transceiver designed for RS-485 and RS-422 communication. It operates from a single 5V supply and integrates a driver and a receiver.
This transceiver supports data transmission rates of up to 2.5Mbps when its drivers are not slew-rate limited. For applications sensitive to EMI and cable reflections, slew-rate limited versions are available, supporting error-free data transmission up to 250kbps. The device draws minimal supply current, ranging from 120µA to 500µA when unloaded or fully loaded with disabled drivers. A low-current shutdown mode further reduces consumption to 0.1µA.
Drivers are protected against short-circuit currents and excessive power dissipation through thermal shutdown circuitry. The receiver input features a fail-safe mechanism that ensures a logic-high output when the input is open-circuited. The MAX483ESA is designed for half-duplex applications.
Typical applications include low-power RS-485 and RS-422 communication, level translation, and transceivers for EMI-sensitive environments such as industrial-control local area networks.

The driver slew rates of the MAX481, MAX485, MAX490, MAX491, and MAX1487 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.
Yes, the MAX481, MAX483, and MAX487 have a low-current shutdown mode in which they consume only 0.1µA.
The MAX487 and MAX1487 feature quarter-unit-load receiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus.
