Webb20 dec. 2015 · 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: Webb9 dec. 2024 · But it's possible for the minimum hold time to be negative (due to built in delay in the data input). This is very common in FPGAs, for example. An I2C device won't have a negative minimum hold time, but …
