DS1033Z-12

Overview

The DS1033Z-12 is a low-power, +3.3V silicon delay line featuring three independent buffered delays within an 8-pin SOIC package. It operates between 2.7V and 3.6V with a nominal delay of 12 ns per output. The device maintains an initial tolerance of ±1.5 ns at +25°C and VCC=3.3V. Over the commercial temperature range (0°C to 70°C), additional tolerance is ±1.0 ns at 3.3V and ±1.5 ns at 2.7V. Active current is typically 25 mA at 3.6V. Input capacitance is 10 pF, and outputs drive one 74F04 gate equivalent.

Feature Summary

• All-silicon timing circuit providing stable and precise performance over temperature and voltage variations
• Three independent logic buffered delays with leading and trailing edge precision that preserves input symmetry
• Standard 8-pin mini-SOIC packaging compatible with vapor phasing, IR, and wave soldering processes

Applications

• Precision timing circuits requiring multiple synchronized signal delays
• Low-voltage digital systems needing reliable all-silicon delay solutions
• Applications demanding high input symmetry preservation across multiple channels

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status for the specific ordering suffix. Check datasheet revisions for updated electrical characteristics. Ensure storage conditions remain within specified limits to prevent degradation. Validate pinout compatibility during integration planning.

Selection Notes

Select this part when three identical delay paths are required in a compact surface-mount package. Verify that the 12 ns nominal delay meets system timing requirements. Consider the 25 mA active current consumption against available power budgets. Ensure operating voltage stays within the 2.7V to 3.6V range for optimal performance.

Part Context

The DS1033 series serves as a low-power alternative to the DS1035 family, optimized for +3.3V operation. Manufactured by Analog Devices Inc./Maxim Integrated, it continues the legacy of Dallas Semiconductor timing components. The Z suffix indicates RoHS-compliant manufacturing standards.

Replacement Considerations

DS1033-12 is the non-RoHS equivalent. DS1033M-12 offers DIP packaging instead of SOIC. DS1035 series provides similar functionality but supports higher voltage ranges.
