Input Tolerance of CY2304NZ

Question: Is CY2304NZ input 5V tolerant?

 

Answer:

The input of CY2304NZ non zero delay buffer device is not 5V tolerant. Due to the input clamping diode, the input needs to be less than VDD + 0.5V. So the Input needs to be < 4.1V (=3.6 + 0.5), according to datasheet.
