Product Summary

The MAX3488EESA is a 3.3V, low-power transceiver for RS-485 and RS-422 communication. It features fullduplex communication. The MAX3488EESA contains one driver and one receiver. The MAX3488EESA features slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission at data rates up to 250kbps. 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 MAX3488EESA receiver input has a fail-safe feature that guarantees a logic-high output if both inputs are open circuit.
