PRODUCTION DATA
A proper power-up sequence with inputs held at ground should be followed as listed:
The power supply can be any voltage between the minimum and maximum supply voltage rating located in the Recommended Operating Conditions. The recommendation is to first power-up the input supply rail to help avoid internal floating while the output supply rail ramps up. However, both power-supply rails can be ramped up simultaneously.
Each VCC pin must have a good bypass capacitor to prevent power disturbance. For devices with a single supply, 0.1 µF is recommended. If there are multiple VCC pins, 0.01 µF or 0.022 µF is recommended for each power pin. It is acceptable to parallel multiple bypass capacitors to reject different frequencies of noise. 0.1-µF and 1-µF capacitors are commonly used in parallel. The bypass capacitor must be installed as close to the power pin as possible for best results.
