DS1005M-125

Overview

The DS1005M-125 is a 5-tap silicon delay line in an 8-pin DIP package. It provides equally spaced delays of 25 ns, 50 ns, 75 ns, 100 ns, and 125 ns at Taps 1 through 5. The device operates on a single +5V supply (4.75V to 5.25V) with an active current of 40mA typical. It features TTL/CMOS compatibility, ±2ns or ±3% delay tolerance, and supports both leading and trailing edge accuracy. The component is designed for low-power CMOS applications and offers reliable performance across the commercial temperature range.

Feature Summary

• Provides five equally spaced output taps for precise timing control
• Maintains high accuracy on both rising and falling signal edges
• Compatible with standard TTL and CMOS logic families
• Capable of driving up to ten 74LS loads per tap

Applications

• Timing synchronization in digital circuits
• Pulse width modulation systems
• Signal processing delay lines
• Clock distribution networks

Procurement Notes

Verify the specific suffix 'M' confirms the 8-pin DIP package configuration. Confirm that the '-125' designation matches the required 125 nanosecond maximum delay specification. Ensure the operating environment remains within the specified 0°C to 70°C temperature range. Check for lead-free compliance requirements if applicable to the target assembly process.

Selection Notes

Select this component when fixed, equally spaced delays are required without programmability. Compare against other dash numbers in the DS1005 series if different delay values are needed. Consider the 8-pin DIP form factor for through-hole mounting constraints. Evaluate the drive capability against the fan-out requirements of the downstream logic gates.

Part Context

This part belongs to the DS1005 family of all-silicon delay lines manufactured by Analog Devices / Maxim Integrated. The family includes variations such as the 14-pin DIP and 16-pin SOIC packages. The 'M' suffix specifically denotes the space-saving 8-pin DIP option, maintaining pinout compatibility with standard hybrid delay line products.
