Notes: 1. All typical values are at VCC=3.3V or VCC=5V, and TA=25°C
2. 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.
3. Test conditions are C1−C4=0.1μF at VCC=3.3V ± 0.3V; C1=0.047μF, C2−C4=0.33μF at VCC=5 V±0.5V.
4. Pulse skew is defined as |tPLH − tPHL| of each channel of the same device.
