MAX3485CPA+

The MAX3485CPA+ is a slew-rate-limited Low-power Transceiver for RS-485/RS-422 communication. Each part contains one driver and one receiver. The MAX3485 feature 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 10Mbps. 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 both inputs are open circuit.

• Operate from a single 3.3V supply - No charge pump
• Interoperable with +5V logic
• Slew-rate limited for errorless data transmission
• 2nA Low-current shutdown mode
• -7 to +12V Common-mode input voltage range
• Allows up to 32 transceivers on the bus
• Industry-standard 75176 pinout
• Current-limiting and thermal shutdown for driver overload protection
