DS1135Z-8

Overview

The DS1135Z-8 is a high-speed, all-silicon delay line featuring three independent buffered delays in an 8-pin SOIC package. It operates on a +5V supply (4.75V to 5.25V) and provides a nominal delay of 8ns per output with ±1.0ns initial tolerance at +25°C. The device maintains stable timing over temperature (-40°C to +85°C) and voltage variations, with a maximum drift of ±1.5ns across the industrial range. Each output can drive up to 10 LS loads, ensuring robust signal integrity for complex timing applications.

Feature Summary

• Three independent buffered delay channels integrated into a single package
• Precise leading and trailing edge accuracy preserves input symmetry
• Stable and precise timing performance over temperature and voltage variations
• Compatible with vapor phasing, IR, and wave soldering processes

Applications

• High-speed timing circuits requiring multiple synchronized delays
• Replacement for legacy DS1013 and DS1035 delay lines
• Pulse width modulation and signal conditioning systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm RoHS compliance status and exact package variant. Confirm that the required delay value matches the standard 8ns specification for this part number before procurement.

Selection Notes

Select this component when three identical delay paths are required within a single footprint. Ensure the system operates at +5V, as this series differs from the 3V DS1135L. Verify that the 8ns delay meets the application requirements compared to other available tap values like 6ns or 10ns.

Part Context

The DS1135 series represents a low-power, high-speed evolution of the popular DS1013 and DS1035 families. Designed for applications needing multiple delay taps, it offers faster performance than its predecessors while maintaining the reliability of an all-silicon solution in a compact 8-pin SOIC form factor.

Replacement Considerations

Officially recommended as a direct replacement for the DS1013 and DS1035. When substituting, verify that the original circuit supports the +5V operating voltage and that the 8ns delay value aligns with the previous design specifications.
