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.
