5. 6 COP Pin Leakage Current (ICOH), COP Pin Sink Current (ICOL)
The COP pin sink current (ICOL) is the current that flows through the COP pin when VCOP = VSS + 0.5 V
after the initial status. After that, the current that flows through the COP pin when V1 = V2 = V3 = V4 =
6 V and VCOP = VDD is the COP pin leakage current (ICOH).
5. 7 DOP Pin Source Current (IDOH), DOP Pin Sink Current (IDOL)
The DOP pin sink current (IDOL) is the current that flows through the DOP pin when VDOP = VSS + 0.5 V
after the initial status. After that, the current that flows through the DOP pin when VVMP = VDD − 2 V
and VDOP = VDD − 0.5 V is the DOP pin source current (IDOH).
