CY7C65630 uses the CMOS technology. Hence, the static power consumption remains the same irrespective of active LOW or active HIGH OVR[x] pin. The dynamic power consumption depends on the transients in switching the supply voltage and the capacitance. Hence, the dynamic power consumption will be lesser in the case of an active LOW circuit and slightly higher in case of an active HIGH circuit. But, in terms of the normal functioning of the device, the OVR[x] pins are static and hence the power consumption will only be because of the leakage current (max +/- 10uA).
