    APPLICATION NOTES
    HIGH FREQUENCY RESPONSE
    The DDU8C3 tolerances are guaranteed for input
    pulse widths and periods greater than those
    specified in the test conditions. Although the
    device will function properly for pulse widths as
    small as 40% of the total delay and periods as
    small as 80% of the total delay (for a symmetric
    input), the delays may deviate from their values at
    low frequency. However, for a given input
    condition, the deviation will be repeatable from
    pulse to pulse. Contact technical support at Data
    Delay Devices if your application requires device
    testing at a specific input condition.
    POWER SUPPLY BYPASSING
    The DDU8C3 relies on a stable power supply to
    produce repeatable delays within the stated
    tolerances. A 0.1uf capacitor from VDD to GND,
    located as close as possible to the VDD pin, is
    recommended. A wide VDD trace and a clean
    ground plane should be used.
