Product Summary

The MAX487ESA is a low-power transceiver for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX487ESA features reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX487ESA is not limited, allowing them to transmit up to 2.5Mbps. The transceiver draws between 120μA and 500μA of supply current when unloaded or fully loaded with disabled drivers. Additionally, the MAX487ESA has a low-current shutdown mode in which they consume only 0.1μA. All parts operate from a single 5V supply. Driver is short-circuit current limited and is 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.
