11 Power Supply Recommendations
The V
CC
voltage should be connected to the same power source used for logic device connected to TIN pins.
V
CC
should be between 4.5V and 5.5V.
12 Layout
12.1 Layout Guidelines
Keep the external capacitor traces short. This is more important on C1 and C2 nodes that have the fastest rise
and fall times.
