Hi guys
I am wondering if 2,4 volts is the minimum required to switch on the output of this IC. Because I am trying to check the voltage output of a project with 1,8 volts. Trying to connect to the Arduino is not a good idea, because it requires a minimum of 3 volts to detect a HIGH state in its digital input. So, if the ULN2803 is not a good idea to monitoring 1,8 volts, which IC do you recommend that meets the need of a low voltage input? Thanks a lot!
