EC340H-04 多功能循环定时IC，睡眠低功耗，静态电流5uA，电压工作范围宽，可以输出高

电平和低电平两种状态。8种定时模式，可设定时间为：

                                                                      10小时ON~ 14小时OFF

                                                                         8小时ON~ 16小时OFF

                                                                         7小时ON~ 17小时OFF

                                                                         6小时ON~ 18小时OFF

                                                                         5小时ON~ 19小时OFF

                                                                         4小时ON~ 20小时OFF

                                                                         3小时ON~ 21小时OFF

                                                                         2小时ON~ 22小时OFF

         定时芯片通电后，如果晶振不起振，OUT 输出高平。晶振起振后OUT 输出低电平，定时时间

到OUT 输出高电平。TEST快速测试，按下TEST，定时8小时，OUT就相应的闪8次。高电平输出有

20mA、低电平输出有40mA，用选择脚选择定时模式。
