MAX3387EEUG-T

The MAX3387EEUG-T belongs to MAX3387E 3V powered EIA/TIA-232 and V.28/V.24 family which is a communications interface with low power require ments, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection and it has three receivers and three transmitters. The MAX3387E is capa- ble 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. 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 0.1F capacitors for operation from a +3.3V supply.

The features of MAX3387EEUG-T can be summarized as (1)VL pin for compatibility with mixed-voltage systems; (2)±15kV ESD protection on Rx inputs and Tx outputs; (3)low 300A supply current; (4)guaranteed 250kbps data rate; (5)1A autoshutdown plus with receivers active; (6)meets EIA/TIA-232 specifications down to 3.0V.
