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).
