UC300Eth Inputs specifications
Posted: Sat Apr 26, 2025 11:03 amFor those interested, i did measure the UC300eth port #1 inputs and here is what i get :
current draw when grounded : 1 mA => pull-up resistor : 5 kohms
low state if input voltage <= 1.4V
high state if input voltage : >= 3.6V
(CMOS 5V Schmitt trigger)
This is important to know when interfacing DIY circuits for a good compatibility.
