EC340H-04 多功能循環(huán)定時(shí)IC，睡眠低功耗，靜態(tài)電流5uA，電壓工作范圍寬，可以輸出高

電平和低電平兩種狀態(tài)。8種定時(shí)模式，可設(shè)定時(shí)間為：

                                                                      10小時(shí)ON~ 14小時(shí)OFF

                                                                         8小時(shí)ON~ 16小時(shí)OFF

                                                                         7小時(shí)ON~ 17小時(shí)OFF

                                                                         6小時(shí)ON~ 18小時(shí)OFF

                                                                         5小時(shí)ON~ 19小時(shí)OFF

                                                                         4小時(shí)ON~ 20小時(shí)OFF

                                                                         3小時(shí)ON~ 21小時(shí)OFF

                                                                         2小時(shí)ON~ 22小時(shí)OFF

         定時(shí)芯片通電后，如果晶振不起振，OUT 輸出高平。晶振起振后OUT 輸出低電平，定時(shí)時(shí)間

到OUT 輸出高電平。TEST快速測(cè)試，按下TEST，定時(shí)8小時(shí)，OUT就相應(yīng)的閃8次。高電平輸出有

20mA、低電平輸出有40mA，用選擇腳選擇定時(shí)模式。
