MAX3389E:2.5V、±15kV ESD保护、RS-232收发器,用于PDA和蜂窝电话

+2.5V RS-232收发器,适用于PDA HotSync

The MAX3388E/MAX3389E are 2.5V-powered EIA/TIA-232 and V.28/V.24 communications interfaces with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection. The MAX3388E/MAX3389E have two 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. In addition to the traditional RS-232 I/O, these devices have dedicated logic-level I/O pins for additional device-to-device handshaking. During shutdown the logic-level I/O pins are active for the MAX3389E. An internal 62Ω switch is provided to switch power to external circuitry or modules. A proprietary low-dropout transmitter output stage enables RS-232 compatible performance from a +2.35V to +3.0V supply with a dual charge pump. The charge pump requires only four small 0.1µF capacitors for operation from a +2.5V supply. The MAX3388E/MAX3389E are capable of running at data rates up to 460kbps while maintaining RS-232-compatible output levels. The MAX3388E/MAX3389E have 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 MAX3388E/MAX3389E are available in a space-saving TSSOP package.
