APPLICATION NOTES

HIGH FREQUENCY RESPONSE

The DDU224F 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 DDU224F 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.
