14. For any inverting inputs pulled LOW, non-inverting inputs pulled HIGH, or outputs driven HIGH; static IDD
increases by the current flowing through the corresponding pull-up/down resistor, shown in Figure 7.
15. The initial spike in each current waveform is a measurement artifact caused by the stray inductance of the
current-measurement loop.
