DDU37F-30 Datasheet PDF - Data Delay Devices

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 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.
