DESCRIPTION
The DS1033 series is a low-power +3.3 Volt version of the DS1035. It is characterized for operation
over the range of 2.7V to 3.6V.
The DS1033 series of delay lines have three independent logic buffered delays in a single package. It is
available in a standard 8-pin DIP, 150-mil 8-pin mini-SOIC.
The device features precise leading and trailing edge accuracies. It has the inherent reliability of an allsilicon delay line solution. The DS1033’s nominal tolerance is ±1.5 ns and an additional tolerance over
temperature and voltage of ±1.0 ns for the faster delays. Detailed specifications are shown in Table 1.
Standard delay values are indicated in Table 1. Customers may contact Dallas Semiconductor at (972)
371-4348 for further information.
