DS1033Z-25

Overview

The DS1033Z-25 is a low-power, all-silicon timing circuit featuring three independent buffered delay lines. It operates within a supply voltage range of 2.7V to 3.6V and functions at temperatures from 0°C to +70°C. The device provides a nominal delay of 25ns per output with an initial tolerance of ±2.0ns. Additional tolerance over temperature and voltage is specified as ±2.0ns at VCC=3.3V and ±3.5ns at VCC=2.7V. It utilizes an 8-pin SOIC package.

Feature Summary

• Three independent logic buffered delays in a single package
• Precise leading and trailing edge accuracy preserves input symmetry
• All-silicon solution offering inherent reliability

Applications

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

Procurement Notes

Verify the specific suffix Z indicates the 8-pin SOIC package configuration. Confirm the -25 designation corresponds to the 25ns delay value. Check current availability status as this component may be discontinued or subject to limited supply constraints depending on the distributor.

Selection Notes

Select this part when three identical delay paths are required in a low-voltage environment. Ensure the operating voltage remains between 2.7V and 3.6V. Verify that the 25ns delay meets system timing requirements and that the ±2.0ns initial tolerance is acceptable for the application.

Part Context

The DS1033 series represents the low-power +3.3V version of the DS1035 family. It integrates three independent delay lines into a compact form factor. The Z suffix typically denotes the surface-mount SOIC package variant within the broader DS1033 product line.

Replacement Considerations

Direct replacements include other parts from the DS1033 series with different delay values (e.g., DS1033Z-10, DS1033Z-20) if timing differs. The DS1035 series offers similar functionality but operates at higher voltages.
