DS1135Z-25

Overview

The DS1135Z-25 is a high-speed, all-silicon delay line featuring three independent buffered delays in an 8-pin SO package. It operates on a +5V supply with a nominal delay of 25ns per output. The device guarantees an initial tolerance of ±1.5ns at +25°C and maintains stability over temperature (-40°C to +85°C) with a maximum drift of ±2ns. Key electrical characteristics include a typical output rise/fall time of 2.5ns, an active current of 35mA, and input leakage within ±1.0µA. It supports vapor, IR, and wave soldering methods.

Feature Summary

• Provides three independent logic buffered delays within a single package
• Maintains precise leading and trailing edge accuracy to preserve input symmetry
• Offers inherent reliability through an all-silicon timing circuit solution
• Capable of driving up to 10 LS loads per output

Applications

• Precision timing circuits requiring stable delays over voltage and temperature variations
• Replacement for legacy DS1013 and DS1035 delay lines
• Systems utilizing vapor, IR, or wave soldering processes

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm RoHS compliance status, as indicated by symbols such as '+', '#', or '-' in the package code. Ensure the selected part matches the required commercial or industrial temperature range specifications before finalizing procurement orders.

Selection Notes

Select this component when a high-speed, low-power +5V delay line is required with three independent channels. The 25ns delay value suits applications needing moderate signal shifting. Consider the ±1.5ns initial tolerance and ±2ns over-temp/voltage drift for precision requirements. Verify compatibility with standard 8-pin SOIC footprints and ensure the driving load does not exceed 10 LS loads per output.

Part Context

The DS1135 series represents the high-speed, +5V variant of the popular DS1013 and DS1035 families. It is designed as the fastest 3-in-1 delay line solution available from the manufacturer. The Z suffix denotes the 8-pin Small Outline (SO) package with 150-mil width, which is suitable for surface-mount assembly techniques including reflow soldering.

Replacement Considerations

Officially recommended as a replacement for DS1013 and DS1035 models. Verify pinout compatibility and electrical parameter alignment, particularly regarding the +5V operation requirement, as lower voltage variants like the DS1135L are not direct substitutes.
