Note 18: Rate of voltage change must be less then 0.5 V/ms.

Note 19: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.

TRI-STATE mode and tied to ground, all outputs low and tied to ground. The Clock Monitor and the comparators are disabled.
