Upon the application of power, the DS1091L output is
held in the low state until t
removes any possibility of erroneous output transitions
during initial power-up.

To achieve best results, it is highly recommended that
decoupling capacitors are used on the IC power-supply
pins. Typical values of decoupling capacitors are 0.01µF
and 0.1µF. Use a high-quality, ceramic, surface-mount
capacitor, and mount it as close as possible to the V
and GND pins of the IC to minimize lead inductance.
