DS1005S-250

Overview

The DS1005S-250 is a five-tap silicon delay line providing equally spaced delays ranging from 50 ns to 250 ns. It operates on a single +5V supply with an active current of 40 mA typical. The device features TTL/CMOS compatibility and offers ±2 ns or ±3% delay tolerance. It is housed in a 16-pin SOIC package and functions within a temperature range of 0°C to 70°C.

Feature Summary

• Provides five equally spaced output taps for precise timing control
• Ensures stable and accurate delays across voltage and temperature variations
• Features low-power CMOS technology compatible with standard logic families

Applications

• Timing signal generation in digital circuits
• Pulse width modulation applications
• Clock distribution networks requiring specific phase offsets

Procurement Notes

Verify the exact suffix against official documentation to confirm package type and tape-and-reel availability. Confirm RoHS compliance status as manufacturing processes may change. Ensure the ordering code matches the required delay value and operating temperature range before finalizing procurement.

Selection Notes

Select this component when fixed, equally spaced delays are required without programmability. Verify that the 5V supply voltage aligns with system power rails. Consider the 16-pin SOIC footprint during PCB layout planning to ensure adequate clearance for the surface-mount package.

Part Context

This part belongs to the DS1005 family of all-silicon delay lines. It serves as a direct replacement for older hybrid delay line technologies while offering superior reliability. The series includes variants with different delay values and packaging options to suit various design constraints.

Replacement Considerations

DS1005S-200 provides shorter delays (40ns to 200ns). DS1005S-100 offers reduced delays (20ns to 100ns). Verify pinout compatibility if substituting with other delay line ICs.
