输入信号经过施密特触发器接入输入数据存储器。当无信号输入时，电压不确定。因为浮空输入既高阻输入，可以认为输入端口阻抗无穷大，这样可以检测到微弱的信号。（相当于电压表测电压，如果电压表内阻不够大而外部阻抗比较大，则电压表分压会比较小）。此时输入高电平即高电平，输入低电平即低电平。但是外 … See more 浮空输入在外界没有输入时状态不确定，可能对电路造成干扰。为了使得电路更加稳定，不出现没有输入时端口的输入数据被干扰 （比如手碰一下电压就发生变化）。这时就需要下拉电阻（或上 … See more 开漏输出即漏极开路输出。这种输出方式指场效应管漏极开路输出。需要接上拉电阻才能输出1。漏极经上拉电阻接到电源，栅极输出0时，场效应管截止（阻抗无线大），电压被分到场效应管上，此时输出为1。当栅极输出1时， … See more 推挽输出既可以输出1，又可以输出0。但是无法调节输出电压，因为输出高低电平均为三极管输入端电压，此电压在由芯片内部供电，无法改变。推挽输出任意时刻只有一路工作。上图为输出 … See more WebNov 29, 2015 · You cannot read it, because the hardware does not support reading the "side" of it you write to.
