DESCRIPTION
The DS1004 is a 5-tap all silicon delay line which can provide 2, 3, 4, or 5 ns tap-to-tap delays within a
standard part family. The device is Dallas Semiconductor’s fastest 5-tap delay line. It is available in a
standard 8-pin DIP and 150 mil 8-pin mini-SOIC. The device features precise leading and trailing edge
accuracies and has the inherent reliability of an all-silicon delay line solution.
The DS1004 is specified for tap-to-tap tolerances as shown in Table 1. Each device has a minimum
input-to-tap 1 delay of 5 ns. Subsequent taps (taps 2 through 5) are precisel y delayed by 2, 3, 4, or 5 ns.
See Table 1 for details. Input to Tap Tolerance over temperature and voltage is ±1.5 ns in addition to the
nominal delay tolerance. Nominal tap-to-tap tolerances range from ±0.75 ns to ±1.0 ns. Each output is
capable of driving up to 10 LS loads.
For customers needing non-standard delay values, the Late Package Program (LPP) is available.
