† All typical values are at VCC = 3.3 V or VCC = 5 V, and TA = 25°C.
‡ Short-circuit durations should be controlled to prevent exceeding the device absolute power dissipation ratings, and not more than one output
should be shorted at a time.
NOTE 4: Test conditions are C1−C4 = 0.1
µF at VCC = 3.3 V ± 0.3 V; C1 = 0.047 µF, C2−C4 = 0.33 µF at VCC = 5 V ± 0.5 V.
