DS1033Z-30

Overview

The DS1033Z-30 is a low-power, all-silicon timing circuit featuring three independent buffered delay lines within an 8-pin SOIC package. It operates on a single supply voltage ranging from 2.7V to 3.6V, with a nominal value of 3.3V. The device provides a standard delay of 30ns per output channel. Initial delay tolerance is specified at ±2.0 ns under nominal conditions (+25°C, VCC=+3.3V). Over the operating temperature range of 0°C to 70°C, the additional tolerance varies based on supply voltage: ±2.0 ns at 3.3V and ±5.0 ns at 2.7V. The component ensures precise leading and trailing edge accuracy to preserve input symmetry.

Feature Summary

• Three independent logic buffered delays integrated into a single package
• Precise leading and trailing edge accuracies that maintain input signal symmetry
• All-silicon construction providing inherent reliability without discrete components

Applications

• Precision timing circuits requiring multiple synchronized delayed signals
• Low-voltage digital systems needing stable delay elements over temperature variations
• Signal processing applications preserving waveform symmetry

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and halogen-free status according to manufacturer documentation. Confirm current availability status as distribution channels may list this part as discontinued or limited stock. Ensure the selected package matches the required PCB footprint for the 8-pin SOIC (150-mil) configuration before finalizing orders.

Selection Notes

Select the DS1033Z-30 when a fixed 30ns delay is required for each of the three channels. Compare against other series members if different delay values like 8ns or 10ns are needed. Consider the ±2.0 ns initial tolerance and the expanded tolerance at lower voltages when designing for tight timing margins in varying environmental conditions.

Part Context

This component belongs to the DS1033 series, which serves as the low-power +3.3V version of the DS1035 family. The series offers various delay options including 8ns, 10ns, 12ns, 15ns, 20ns, 25ns, and 30ns. The Z suffix typically denotes the SOIC package variant with specific manufacturing attributes compared to the DIP version.

Replacement Considerations

The DS1035 is the higher voltage counterpart in the same family. Other DS1033 variants with different delay values (e.g., DS1033-10, DS1033-20) share the same pinout and functionality but provide different timing characteristics.
