The q denotes specifications which apply over the full operating
temperature range.
Note 1: To 90% of the final value, COUT = 0.1µF, ROUT = 2.9k.
Note 2: To 10% of the final value, COUT = 0.1µF, ROUT = 2.9k.
Note 3: To 50% of the initial value, COUT = 0.1µF, ROUT = 2.9k.
Note 4: Measured current data is per channel.
Note 5: Input logic low equal to 0V, high equal to 5V.
Note 6: VPPIN = 0V when switching from Hi-Z to VCCIN.
