7.3 Power Supply Recommendations

Due to the fast output edges, it is critical to have bypass capacitors on the supply pin to prevent supply ringing and false triggers and oscillations. Bypass the supply directly at each device with a low ESR 0.1µF ceramic SMT bypass capacitor as directly as possible between the supply pins and ground. Narrow peak currents will be drawn during the output transition timedue to the push-pull output device. These narrow pulses can cause poorly bypassed supply lines and poor grounds to ring, possibly causing common mode variations that can eat into the input voltage range and create an inaccurate comparison or even oscillations or false-triggers
