Doc #97020 DATA DELAY DEVICES, INC. 2/5/97 3 Mt. Prospect Ave. Clifton, NJ 07013 5-TAP, TTL-INTERFACED FIXED DELAY LINE (SERIES DDU66F)
FEATURES
Five equally spaced outputs Fits standard 14-pin DIP socket Low profile Auto-insertable Input & outputs fully TTL interfaced & buffered
10 T2L fan-out capability
The DDU66F-series device is a 5-tap digitally buffered delay line. The signal input (IN) is reproduced at the outputs (T1-T5), shifted in time by an amount given by the device dash number. For dash numbers less than 25, the total delay of the line is measured from T1 to T5, with the nominal value given by the dash number. The nominal tap-to-tap delay increment is given by 1/4 of this number. The inherent delay from IN to T1 is nominally 3.5ns. For dash numbers greater than or equal to 25, the total delay of the line is measured from IN to T5, with the nominal value given by the dash number. The nominal tap-to-tap delay increment is given by 1/5 of this number.

Although the device will function properly for pulse widths as small as 40% of the total delay and periods as small as 80% of the total delay (for a symmetric input), the delays may deviate from their values at low frequency. However, for a given input condition, the deviation will be repeatable from pulse to pulse. Contact technical support at Data Delay Devices if your application requires device testing at a specific input condition. POWER SUPPLY BYPASSING The DDU66F relies on a stable power supply to produce repeatable delays within the stated tolerances. A 0.1uf capacitor from VCC to GND, located as close as possible to the VCC pin, is recommended. A wide VCC trace and a clean ground plane should be used.
