IC is designed to open drain output line and convenient ", for example, the output of two or more than two NAND gate end connected on the same line, these data will be on the NAND gate (state level) with a wire transfer out. The open drain structure is an output without pull-up. ...
Push-pull output is best suited for communication interfaces that have single direction lines (e.g SPI, UART etc.). Open drain is commonly used for bidirectional single line communication interfaces, where more than two devices are connected on the same line(e.g I2C, One-Wire etc.) Open dr...
(General Purpose Input Output,简称为GPIO或总线扩展器,利用工业标准I2C、SMBus?或SPI?接口简化了I/O口的扩展。当微控制器或芯片组没有足够的I/O端口,或当系统需要采用远端串行通信或控制时,GPIO产品能够提供额外的控制和监视功能。)但是在配置GPIO管脚的时候,常会见到两种模式:开漏(open-drain,漏极开路)和推挽(...
Output)管脚的时候,常会见到两种模式:开漏(open-drain,漏极开路)和推挽(push-pull)。对此两种模式,有何区别和联系,下面整理了一些资料,来详细解释一下:一、Push-Pull推挽输出1、原理输出的器件是指输出脚内部集成有一对互补的MOSFET:当Q1导通、Q2截止时输出高电平;而当Q1截止导通、Q2导通时输出低电平。Push-Pull...

在input有high信号的话,transistor则为ON,此时Output和Groud形成通路使得Output输出为Low 在input有low信号的话,transistor则为OFF,此时Output为Hi-inpedence状态。 Hi-impedence的意思是阻抗很高,Low和High不能区别的状态。 所以一般情况下,Output会连接有一个Pull-up电阻,在input为low时,能把output的状态从Hi-impede...

An open drain output circuit includes a package having a reference potential section on at least a portion thereof. An output terminal of the circuit disposed on the package is connected through a load resistor to an external power supply. A common terminal also disposed on the package is ...
An open-drain output is an output which can only be driven low, not high; the output is either low or floating. Essentially the output is simply connected to the drain pin of a transistor (hence the term open-drain). When the Control line is driven high then the transistor short-...
