DESCRIPTION
The DS1044 series is a 4-in-1 version of the low-power, +5 volt, high speed DS1035.
The DS1044 series of delay lines have four independent logic buffered delays in a single package. The
device is Dallas Semiconductor’s fastest 4-in-1 delay line. It is available in a standard 14-pin DIP and
14-pin SOIC.
The device features precise leading and trailing edge accuracies. It has the inherent reliability of an
all-silicon delay line solution. The DS1044’s nominal tolerance is ±1.5 ns and an additional tolerance
over temperature and voltage of ±1.0 ns for the faster delays. Each output is capable of driving up to 10
LS loads.
Standard delay values are indicated in Table 1.
