MAX3232EUE+T

The MAX3222/MAX3232/MAX3237/MAX3241 transceivers have a proprietary low-dropout transmitter output stage enabling true RS-232 performance from a 3.0V to 5.5V supply with a dual charge pump. The devices require only four small 0.1μF external chargepump capacitors. 

The MAX3222, MAX3232, and MAX3241 are guaranteed to run at data rates of 120kbps while maintaining

RS-232 output levels. 

The MAX3237 is guaranteed to run at data rates of 250kbps in the normal operating mode and 1Mbps in the MegaBaud™ operating mode, while maintaining RS-232 output levels.

The MAX3222/MAX3232 have 2 receivers and 2 drivers. The MAX3222 features a 1μA shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1μA supply current. The MAX3222 and MAX3232 are pin, package, and functionally compatible with the industry-standard MAX242 and MAX232, respectively.

MAX3222/MAX3232/MAX3237/MAX3241收发机有一个专有的低压差发射机输出级，使真正的RS-232性能从3.0V

到5.5V电源与双电荷泵。这些设备只需要四个小的0.1μF外部充电泵电容器。

MAX3222、MAX3232和MAX3241保证以120kbps的数据速率运行，同时保持RS-232输出电平。

MAX3237保证在正常工作模式下以250kbps的数据速率运行，在兆波特模式下以1Mbps的数据速率运行™ 

操作模式，同时保持RS-232输出电平。

MAX3222/MAX3232有2个接收器和2个驱动器。MAX3222采用1μ一种关机模式，在便携式系统中可降低功耗并

延长电池寿命。它的接收器在关机模式下保持活动状态，允许仅使用1个端口来监视调制解调器等外部设备μ电

源电流。MAX3222和MAX3232分别与工业标准MAX242和MAX232引脚、封装和功能兼容。
