MAX3490CSA+

MAX3490CSA+ is a 3.3V, low-power transceiver for RS-485 and RS-422 communication. The part contains one driver and one receiver. 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 circuits. Applications include low-power RS-485/RS-422 transceivers, telecommunications, transceivers for EMI-sensitive applications, industrial-control local area networks.

• Operates from a single 3.3V supply-no charge pump
• Allows up to 32 transceivers on the bus
• Current-limiting and thermal shutdown for driver overload protection
• Common-mode input voltage range from -7V to +12V
• Interoperable with +5V logic
• 10Mbps guaranteed data rate
• Full duplex communication
• (tPLH - tPHL) driver propagation delay skew is 8ns max at RL=27ohm, VCC=3.3V, TA=+25°C
• 8 SO package
• Temperature range from 0°C to +70°C
