Digital current
*
Output source (single pin) 0.6 mA V
OH
= 2.3 V, 25 °C
Output sink (single pin) 0.6 mA V
OL
= 0.5 V, 25 °C
Input leakage current 50 nA

In order to ensure that the input capacitance can charge quickly enough to get an accurate reading, the total input
impedance, including source, should be less than 75 k
Ω.
