APPLICATION NOTES
HIGH FREQUENCY RESPONSE
The DDU7F 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 20% of the total delay and periods as
small as 40% 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 DDU7F relies on a stable power supply to
produce repeatable delays within the stated
tolerances. A 0.1uf capacitor from VCC to GND,
located as close as possible to the VCC pin, is
recommended. A wide VCC trace and a clean
ground plane should be used.
