MAX3386E集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

General Description

The MAX3386E 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 MAX3386E has two receivers and three transmitters. All RS-232 inputs and outputs are protected to ±25kV 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 MAX3386E is capable of running at data rates up to 250kbps while maintaining RS-232 compliant output levels.

The MAX3386E 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 MAX3386E is available in a space-saving TSSOP package.
