MAX487 - RS-485 RS-422 Transceiver

MAX487 - RS-485 RS-422 Transceiver

The MAX487 is low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX487 feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps.

These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. Additionally, MAX487 have a low-current shutdown mode in which they consume only 0.1µA. All parts operate from a single 5V supply.

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 MAX487 feature quarter-unit-load receiver input impedance, allowing up to 128 bus,  the MAX487 is designed for half-duplex applications.
