MAX3387E：3V、±15kV ESD保护、AutoShutdown Plus RS-232收发器，用于PDA和蜂窝电话

独立的逻辑供电电源确保兼容混合ASIC逻辑电平

The MAX3387E 3V powered EIA/TIA-232 and V.28/V.24 is a communications interface with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection. The MAX3387E has three receivers and three transmitters. All RS-232 inputs and outputs are protected to ±15kV using the IEC 1000-4-2 Air-Gap Discharge method, ±8kV using the IEC 1000-4-2 Contact Discharge method, and ±15kV using the Human Body Model. A proprietary low-dropout transmitter output stage enables true RS-232 performance from a +3.0V to +5.5V supply with a dual charge pump. The charge pump requires only four small 0.1µF capacitors for operation from a +3.3V supply. The MAX3387E is capable of running at data rates up to 250kbps while maintaining RS-232 compliant output levels. The MAX3387E has a unique VL pin that allows interoperation in mixed-logic voltage systems. Both input and output logic levels are pin programmable through the VL pin. The MAX3387E is available in a space-saving TSSOP package.

关键特性 VL Pin for Compatibility with Mixed-Voltage Systems ±15kV ESD Protection on Rx Inputs and Tx Outputs Low 300µA Supply Current Guaranteed 250kbps Data Rate 1µA AutoShutdown Plus™ with Receivers Active Meets EIA/TIA-232 Specifications Down to 3.0V
