DS1033Z-20

Overview

The DS1033Z-20 is a low-power, +3.3V silicon delay line from the DS1033 series, characterized for operation between 2.7V and 3.6V. It integrates three independent logic buffered delays within an 8-pin SOIC package. The nominal delay per output is 20ns with an initial tolerance of ±1.5ns at +25°C and VCC=+3.3V. Over the operating temperature range of 0°C to 70°C, the additional tolerance is ±1.5ns at VCC=3.3V and ±2.5ns at VCC=2.7V. The device features precise leading and trailing edge accuracies that preserve input symmetry.

Feature Summary

• All-silicon timing circuit providing inherent reliability
• Three independent buffered delay channels in a single package
• Stable and precise performance over temperature and voltage variations
• Leading and trailing edge precision preserves input signal symmetry

Applications

• Precision timing circuits requiring multiple synchronized delays
• Low-voltage digital systems needing stable delay elements
• Applications preserving input signal symmetry across multiple outputs

Procurement Notes

Verify the specific suffix Z indicates the 8-pin mini-SOIC (150-mil) package configuration. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated or Dallas Semiconductor depending on production lot. Ensure compatibility with standard surface-mount soldering processes including vapor phasing, IR, and wave soldering methods.

Selection Notes

Select this component when three identical delay paths are required in a low-voltage environment. Verify that the 20ns nominal delay meets system timing requirements. Check that the supply voltage remains within the 2.7V to 3.6V range to maintain specified accuracy. Consider the 8-pin SOIC footprint constraints during PCB layout design.

Part Context

The DS1033 series serves as the low-power +3.3V version of the DS1035. It provides an all-silicon alternative to discrete delay components. The family includes various delay values ranging from 8ns to 30ns. The Z suffix specifically denotes the surface-mount SOIC package variant.

Replacement Considerations

DS1033Z-10: 10ns delay value. DS1033Z-30: 30ns delay value. DS1033M-20: Same electrical specifications but in 8-pin DIP package.
