Maxim Integrated (MAX3491ECSD+T) Transceiver RS422, RS485

Product OverviewThe MAX3491ECSD+T is a 3.3V powered, ±15KV ESD protected true RS485/RS422transceiver in 14 pin NSOIC package. This low power transceiver contains onedriver and one receiver. The MAX3491E transmits up to 15Mbps and it has enhancedESD protection. All transmitter outputs and receiver inputs are protected to±15KV using IEC 1000-4-2 air-gap discharge, ±8KV using IEC 1000-4-2 contactdischarge and ±15KV using human body model. Driver is short circuit currentlimited and it is protected against excessive power dissipation by thermalshutdown circuitry that places the driver outputs into a high impedance state.The receiver input has a fail-safe feature that provides logic high output ifboth inputs are open circuit. The MAX3491E is used in EMI sensitiveapplications, integrated services, digital networks and packet switching.Supply voltage range from 3V to 3.6VOperating temperature range from 0°C to 70°CFull duplex communicationOperate from a single +3.3V supply and no charge pump is requiredInteroperable with +5V Logic2nA low current shutdown modeCommon mode input voltage range from -7V to +12VDriver/receiver enable functionApplicationsCommunications & Networking, IndustrialProduct InformationDevice Type: TransceiverIC Interface Type: RS422, RS485No. of Drivers: 1DriversNo. of Receivers: 1ReceiversSupply Voltage Min: 3VSupply Voltage Max: 3.6VDriver Case Style: NSOICNo. of Pins: 14PinsOperating Temperature Min: 0°COperating Temperature Max: 70°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
