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.
