DS1005M-75

Overview

The DS1005M-75 is a five-tap silicon delay line housed in an 8-pin DIP package. It provides equally spaced output taps with delays of 15 ns, 30 ns, 45 ns, 60 ns, and 75 ns relative to the input signal. The device operates on a single +5V supply with a typical active current of 70 mA. Delay accuracy is specified at ±2 ns or ±3%, whichever is greater, across the commercial temperature range of 0°C to 70°C. It features TTL/CMOS compatibility, low-power CMOS construction, and each tap can drive up to ten 74LS loads.

Feature Summary

• Provides five equally spaced time delay taps for precise signal timing control
• Ensures stable and accurate delays over temperature and voltage variations
• Compatible with standard TTL and CMOS logic families
• Low-profile surface-mount and through-hole packaging options available

Applications

• Signal synchronization and pulse stretching circuits
• Timing adjustment in digital logic systems
• Delay generation for test and measurement equipment

Procurement Notes

Verify the specific suffix 'M' confirms the 8-pin DIP package configuration. Confirm the '-75' designation matches the required 75 ns maximum delay. Ensure the operating environment stays within the 0°C to 70°C commercial temperature range. Check that supply voltage remains within 4.75V to 5.25V limits. Validate pinout compatibility if replacing existing hybrid delay lines.

Selection Notes

Select this part when fixed, equally spaced delays are required without external components. Choose the 8-pin DIP variant for space-constrained through-hole designs. Ensure input pulse width meets minimum specifications to maintain accuracy. Consider thermal management as active current reaches 70 mA. Verify load requirements do not exceed the driving capability of individual taps.

Part Context

This component belongs to the DS1005 family of all-silicon delay lines, which replaces older hybrid technologies. The family offers various delay values ranging from 12 ns to 250 ns. Different package options include 14-pin DIP, 8-pin DIP, and 16-pin SOIC. The silicon construction ensures superior reliability and consistent performance compared to traditional hybrid delay lines.

Replacement Considerations

Direct replacements include other DS1005 variants with different delay values but identical pinouts. Cross-reference with legacy hybrid delay lines requiring similar timing characteristics. Verify that substitute parts support the same 5V logic levels and drive capabilities.
