Hello everybody,
I'm trying to use a 9403 as digital Input to test a device.
This device uses 46k4Ohm Pull-ups with 3,3V
I asumed the input impedance of the Input is very large.
Now i figured out, that this seems not to be the case.
Could anyone please tell me what the input impedance of this module is?
I searched all available documents of the 9403 but to no avail.
Thanks in advance!
Best regards
Balze
