DS1033Z-8+

Overview

The DS1033Z-8+ 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 rating of 3.3V. The device provides a standard delay value of 8ns per output tap, characterized by an initial tolerance of ±1.5ns at +25°C and VCC=3.3V. It maintains stable performance over temperature and voltage variations, ensuring precise leading and trailing edge accuracy that preserves input symmetry.

Feature Summary

• Three independent logic buffered delays integrated into a single package
• Precise leading and trailing edge accuracy preserving input signal symmetry
• Stable and precise timing characteristics across temperature and voltage variations

Applications

• Precision timing circuits requiring multiple synchronized delays
• Low-voltage digital systems needing reliable silicon-based delay elements
• Signal processing applications demanding high edge precision

Procurement Notes

Verify the specific suffix Z indicates the SOIC package variant when sourcing. Confirm the plus sign denotes lead-free compliance status according to manufacturer standards. Ensure the operating environment remains within the specified 0°C to 70°C range for guaranteed electrical parameters. Check for RoHS directive alignment if required by your assembly process.

Selection Notes

Select this component when three identical delay paths are required in a compact surface-mount form factor. Compare against the DIP version if through-hole mounting is necessary. Consider the 8ns delay value against other series options like the DS1033-10 or DS1033-12 if different timing intervals better suit the design requirements.

Part Context

This part belongs to the DS1033 series, which serves as the low-power +3.3V counterpart to the DS1035. Originally developed by Dallas Semiconductor before its acquisition by Maxim Integrated, the series is now managed by Analog Devices Inc. The Z suffix specifically identifies the 150-mil mini-SOIC package configuration.

Replacement Considerations

The DS1033M-8+ serves as the direct through-hole replacement offering identical electrical specifications in an 8-pin DIP package. Other series members such as the DS1033-10 or DS1033-12 provide alternative delay values but share the same functional architecture.
