DS1005M-75+

Overview

The DS1005M-75+ is a five-tap all-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, allowing it to drive up to ten 74LS loads per tap. The component ensures stable performance over voltage and temperature variations.

Feature Summary

• Provides five equally spaced time-delay taps for precise signal timing control
• Ensures high accuracy on both leading and trailing edges of logic pulses
• Compatible with standard TTL and CMOS logic families for easy integration
• Offers low-power CMOS operation with robust reliability over temperature ranges

Applications

• Precision timing circuits requiring fixed delay intervals
• Signal synchronization and pulse shaping in digital systems
• Test equipment and measurement instrumentation requiring accurate time bases

Procurement Notes

Verify the specific suffix '+', which indicates lead-free status and RoHS compliance, against current manufacturer specifications. Confirm the 'M' designation corresponds to the 8-pin DIP package variant. Ensure the '-75' suffix matches the required 75 ns maximum delay for your application. Check for extended temperature range options if operating outside the 0°C to 70°C commercial range.

Selection Notes

Select this model when a fixed 75 ns maximum delay with five intermediate taps is required. The 8-pin DIP package is suitable for through-hole mounting where space allows. Consider the -60 or -100 variants if different delay spans are needed. Verify that the load requirements do not exceed the drive capability of ten 74LS loads per tap. Ensure supply voltage stability within ±5% to maintain specified delay accuracy.

Part Context

This component belongs to the DS1005 family of silicon delay lines, which replaces older hybrid technology devices. The family includes variants with different delay spans (e.g., -60, -100, -125) and packaging options including 14-pin DIP and 16-pin SOIC. The DS1005 series is designed for pin compatibility with legacy delay lines while offering improved reliability and lower power consumption due to its all-silicon construction.

Replacement Considerations

Direct replacements include other DS1005 variants with matching delay characteristics but different packages, such as the DS1005-75 in 14-pin DIP or 16-pin SOIC. Cross-reference with legacy hybrid delay lines only if pinout and electrical characteristics are verified identical. No generic substitutes are recommended without verifying delay accuracy and drive strength.
