DS1135U-12+

Delay Lines IC Overview

The DS1135U-12+ is a high-speed silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It integrates three independent buffered delays within a single package, operating on a +5V supply with a voltage range of 4.75V to 5.25V. The device provides a nominal delay of 12ns per output with an initial tolerance of ±1.0ns at 25°C. It supports an active current of up to 35mA and features low input leakage of ±1.0µA. Designed for robust performance, it maintains precision over temperature and voltage variations across the -40°C to +85°C industrial range.

Delay Lines IC Feature Summary

• Integrates three independent logic buffered delays in a single package
• Maintains stable and precise timing over temperature and voltage variations
• Preserves input symmetry through precise leading and trailing edge accuracy
• Provides inherent reliability as an all-silicon delay line solution

Delay Lines IC Applications

• Timing circuits requiring multiple synchronized signal delays
• Replacement for legacy DS1013 and DS1035 delay lines
• Applications demanding precise pulse width control and signal synchronization

Delay Lines IC Procurement Notes

Verify the specific ordering suffix against official documentation to confirm RoHS compliance status, as indicated by symbols such as '+' or '#'. Confirm that the selected package variant matches the required footprint, noting that the datasheet specifies standard SOIC packages for this series. Ensure compatibility with vapor phasing, IR, and wave soldering processes during assembly planning.

Delay Lines IC Selection Notes

Select the DS1135U-12+ when a fixed 12ns delay is required for three independent channels. Consider the ±1.0ns initial tolerance and ±1.5ns tolerance over temperature/voltage for precision requirements. Verify that the 5V operation aligns with system power rails, as 3V variants belong to the separate DS1135L series. Evaluate the 8-pin package constraints against available board space.

Delay Lines IC Part Context

This component belongs to the DS1135 series of high-speed silicon delay lines. It serves as a modern replacement for older discrete timing solutions and legacy parts like the DS1013 and DS1035. The series is characterized by its all-silicon construction, which eliminates the variability associated with other timing technologies while providing reliable, buffered outputs capable of driving multiple loads.

Delay Lines IC Replacement Considerations

Officially recommended replacements include the DS1013 and DS1035. When substituting, verify pinout compatibility and ensure the new device meets the required delay tolerance specifications. Check if the target application requires the specific 12ns tap value provided by this part number.
