DS1000-250

Overview

The DS1000-250 is a nonprogrammable silicon delay line integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features five fixed taps providing precise signal timing adjustments. The device operates within a supply voltage range of 4.75V to 5.25V and supports a total available delay of 250ns. The first tap delay is specified at 50ns with a uniform step increment of 50ns per tap. It is housed in an 8-DIP package measuring 0.300 inches (7.62mm) width, designed for through-hole mounting.

Feature Summary

• Provides five fixed, nonprogrammable delay taps for precise signal timing control
• Delivers a total cumulative delay of 250ns with consistent 50ns increments between stages
• Operates on a standard single 5V power supply rail
• Utilizes a robust 8-pin DIP package suitable for through-hole PCB integration

Applications

• Signal synchronization in digital communication systems
• Timing adjustment in pulse generation circuits
• Delay compensation in high-speed data transmission lines
• Clock skew correction in synchronous logic designs

Procurement Notes

Verify the specific suffix designation when sourcing replacements, as variations may exist within the DS1000 family. Confirm that the required delay characteristics match the fixed 250ns specification of this part number. Ensure compatibility with 5V logic levels and through-hole assembly processes during procurement planning.

Selection Notes

Select this component when fixed, nonadjustable delay intervals are sufficient for the application requirements. It is appropriate for designs requiring stable timing offsets without the complexity of programmable delay lines. Consider the 8-DIP form factor if space constraints allow for through-hole mounting rather than surface mount alternatives.

Part Context

The DS1000 series represents a family of silicon delay lines designed for reliable timing applications. This specific model provides a moderate delay range suitable for general-purpose digital timing tasks. It serves as a fundamental building block for creating precise time delays in electronic circuits where variable delay elements are unnecessary or undesirable.
