FUNCTIONAL DESCRIPTION
The DDU47F-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 5ns and 25ns. The device
operates from a single 5V supply and is TTL interfaced, capable of driving up
to 10 TTL loads.
