FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DDU37F-series device is a mechanically variable, FAST-TTL interfaced
delay line. The signal input (IN) is reproduced at the tap output (OUT), shifted
by an amount which can be adjusted between TD0 and TD0+ TDVAR, where
TDVAR is given by the device dash number (See Table). The device operates
from a single 5V supply and is TTL interfaced, capable of driving up to 10
TTL loads.

APPLICATION NOTES
Delay Devices if your application requires device
testing at a specific input condition.
HIGH FREQUENCY RESPONSE
The DDU37F 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
POWER SUPPLY BYPASSING
The DDU37F 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.
condition, the deviation will be repeatable from
pulse to pulse. Contact technical support at Data
