FUNCTIONAL DESCRIPTION
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 T_D0 and T_D0+ T_DVAR, where
T_DVAR 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.
