详细说明

定時器電路 AiP6445

産品型号：: AiP6445

産品名称：: 定時器電路

封裝形式：: SIP8

收藏

主要特點
參數類型

AiP6445是CMOS集成电路，由外接阻容网络和预置状态来设定延时时间，设定时限可以从 0.1秒至几十小时。并且具有定时精度高、重复误差小、工作线性度好、功耗低、抗干扰能力强等优点。可以广泛用于机床及其他各种设备的自动控制定时系统。

工具及文檔：
使用注意事項：
電路內部設計了自動複位電路，每次加電時芯片內部各電路即自動進行複位。每次使用時，先預置S1、S2輸入端的狀態，然後重新加電工作。
该电路内有电压比较器，可与外接阻容网络组成震荡器，产生主时钟信号。此时应注意把 TEST端接地或悬空。
若使用外部时钟信号，则应将TEST端接高电平。外部时钟信号由IN (1脚) 输入。
該電路系CMOS器件，所用儀器及工、夾具應接地良好。運輸及保存應采用導電橡膠，並注意防人體的靜電影響

 封裝形式：SIP8
 测试端接地或悬空。若外接时钟信号，测试端接高电平。

應用電路及波形圖、輸出端上升到高電平後振蕩器停止工作、輸出端上升到高電平後放電回路斷開。

"What is that?" Allingham paused in the turning of the handle and stared, aghast, at his companion. There was no mistaking the significance of the remark, and it had been spoken in tones of strange tenderness. Rapidly there swept across the Doctor's mind a sensation of complete conviction. If there was any further proof required of the truth of Gregg's conjecture, surely it was expressed in this apparently insane and yet obviously sincere solicitude on the part of the Clockwork man for an inanimate machine? He recognised in the mechanism before him a member of his own species! Lawrence laid a hand on his friend's shoulder. So, after waiting for the reply of the gentleman whose business it was to give me this free pass, seeing that he could not make up his mind, I left the town without it. “As I live and breathe!” Mr. Everdail spoke gruffly, “I begin to wonder if you shouldn’t be the one to have ‘suspicious’ for a nickname. You have suspected Jeff, and me, and my friend who was with me, and Larsen, here, and his passenger—Captain Parks and now Mimi! It will be Miss Serena next!” Parliament, which had been prorogued for a few days on account of the demise of the king, assembled on the 18th of November. The king delivered a speech, composed by Lord Hardwicke, and revised by Pitt, and containing a passage, said to be inserted by himself, as follows:—"Born and educated in this country, I glory in the name of Briton!" In the addresses these words produced the most enthusiastic responses. "What a lustre," exclaimed the Lords, "doth it cast upon the name of Briton, when you, sir, are pleased to esteem it amongst your glories!" For the rest, the speech expressed the royal determination to prosecute the war with all vigour; praised the magnanimity and perseverance of his good brother, the King of Prussia; and recommended unanimity of action and opinion in Parliament. Nothing could appear more unanimous or more liberal than Parliament. After the song was over, he remained sitting, waiting for what had to come. The rumbling continued, and the room shook more strongly. For some seconds he waited, and then he was standing erect, because he could see. Then he was against the tree while Dara stood behind, waiting. He pressed himself against the bark and he felt himself becoming part of Great Root Tree, becoming the tree itself; and this lasted for all time and no time, and he was separated from it and saw Dara come to where he had pressed, and move delicately and then fiercely upon the bark; then he saw nothing but heard her breathing faster and faster, and all sound stopped ... there was a long silence ... and then her breathing began again, very slowly, very slowly. O why, because brothers and friends all have left me, At last they reached the lane by Eggs Hole Cottage, which with shimmering star-washed front looked towards the south. He stopped, and she slid to the ground. Then suddenly the words came. Well, he had taken it now—it was too late to give it back. Besides, why should he not have it? Those ten pounds probably did not mean much to the Squire, but they meant all things to him and Bessie. He could marry her now. He could take her away, find work on some distant farm, and comfortably set up house. The possibilities of ten pounds were unlimited—at all events they could give him all he asked of life. "Alice."
