What is the relationship between the logic“1”and input voltage of chip pins?
Posted: 31 May 2021, 15:57
The logic“1”voltage of chip pins is the same as the input voltage of the corresponding power domain.
For example,
Input Voltage = 3.3 V => Logic“1”Voltage = 3.3 V
Input Voltage = 4.56789 V => Logic“1”Voltage = 4.56789 V.
For example,
Input Voltage = 3.3 V => Logic“1”Voltage = 3.3 V
Input Voltage = 4.56789 V => Logic“1”Voltage = 4.56789 V.
