Open collector open drain差異

WebThe I2C bus transmits data and clock with SDA and SCL. The first thing to realize: SDA and SCL are open-drain (also known as open-collector in the TTL world), that is I2C master and slave devices can only drive these lines low or leave them open. The termination resistor Rp pulls the line up to Vcc if no I2C device is pulling it down. WebTutorial Summary. We have seen here in this tutorial about the open collector output that it can provide a current sink or current source output depending on the type of bipolar …

WebThe devices mentioned in chapter Relevant Devices feature open-drain functionality. Both the open-drain and the open-collector circuit are capable of having the line pulled low by another device and pulling the line low itself; the difference is that open-collector uses a BJT transistor to pull the line low, while open-drain does so by using a ... Web20 de dez. de 2015 · The Open Drain. A defining characteristic of I2C is that every device on the bus must connect to both the clock signal (abbreviated SCL) and the data signal (abbreviated SDA) via open-drain (or open-collector) output drivers. Let’s take a look at what this actually means. First consider the typical CMOS (inverting) output stage:
