FUNCTIONAL DESCRIPTION
The DDU39F-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 7ns and 25ns. The device operates from a single 5V supply and is TTL interfaced, capable of driving up to 10 TTL loads.
