DS1005M-250+

Overview

The DS1005M-250+ is a 5-tap all-silicon delay line housed in an 8-pin DIP package. It provides five equally spaced output taps with delays ranging from 50 ns to 250 ns, corresponding to the -250 suffix. The device operates on a single +5V supply and features TTL/CMOS compatible logic levels. Delay accuracy is specified at ±2 ns or ±3%, whichever is greater, across the commercial temperature range of 0°C to 70°C. Each tap can drive up to ten 74LS loads, ensuring robust signal integrity for digital timing applications.

Feature Summary

• Provides five equally spaced time-delayed outputs derived from a single input signal
• Ensures precise leading and trailing edge accuracy with stable performance over voltage and temperature variations
• Compatible with standard TTL and CMOS logic families for easy integration
• Utilizes low-power CMOS technology within an auto-insertable, low-profile package

Applications

• Digital pulse stretching and shaping circuits
• Timing synchronization between multiple digital signals
• Delay generation for test and measurement equipment
• Logic circuit timing adjustment and phase alignment

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base model supports various configurations. Confirm that the ambient operating environment remains within the specified 0°C to 70°C range to maintain guaranteed delay accuracy. Ensure supply voltage stability within ±5% of 5.0V to prevent deviation from electrical specifications during operation.

Selection Notes

Select this component when fixed, equally spaced delays are required without programmability. The 8-pin DIP variant offers space savings compared to the 14-pin version while maintaining pin compatibility. Consider the -250 suffix specifically for applications requiring a maximum total delay of 250 ns. Verify load requirements do not exceed the driving capability of ten 74LS equivalents per tap.

Part Context

This device belongs to the DS1005 family of silicon delay lines, which replaces older hybrid technologies with superior reliability. The family includes variants with different total delay times, such as -60, -100, and -200, allowing designers to choose the appropriate timing resolution. The M suffix denotes the compact 8-pin DIP package, distinct from the standard 14-pin DIP or surface-mount SOIC options available in the same series.

Replacement Considerations

Direct pin-compatible replacements include other DS1005 variants with different delay values, provided the timing requirements align. Cross-reference with legacy hybrid delay lines if system board constraints require identical footprint retention. Verify that substitute components meet the same TTL/CMOS compatibility and drive current specifications to ensure functional equivalence.
