Due to the fast output edges, proper decoupling capacitors on the supply pins are critical to prevent supply ringing and false triggers and oscillations. Bypass the supply directly at each supply pin (H_VCC and M_VCC) with a low ESR 0.1μF ceramic SMT capacitor as close as possible between the supply pins and ground. Narrow peak currents are drawn during the output transition time due 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 disturb the input voltage range and create an inaccurate comparison or even oscillations or false-triggers.
