Note:
Supply bypass:
Power supply should have sufficient bypass capacitors to ensure proper operation. Vs power supply should be add a 0.1uF at least ceramic capacitor in parallel with low ESR value and high voltage of the bypass capacitor . It is recommended that a capacitor should be connected between every power supply terminal and ground .
For VCC  should also add a ceramic capacitor with 0.1μF and a low ESR value with 6.8μF-10μF of the bypass capacitor in parallel. All bypass capacitors should be as close as possible to the corresponding power supply root.
