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 precisely delayed by 2, 3, 4, or 5 ns. See
Table 1 for details. Tolerance over temperature and voltage is
±1.5
ns. Nominal tap-to-tap tolerances
range from
±0.5
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.
Customers may contact Dallas Semiconductor at (972) 371–4348 for further details.
