DS1100M-40+

Delay Lines IC Overview

The DS1100M-40+ is a five-tap silicon delay line manufactured by Analog Devices / Maxim Integrated. It provides equally spaced output taps with a nominal total delay of 40ns, resulting in individual tap delays of 8ns, 16ns, 24ns, 32ns, and 40ns. The device operates on a single 5V supply within a voltage range of 4.75V to 5.25V. It utilizes a PDIP-8 package for through-hole mounting and supports an operating temperature range from -40°C to +85°C. Designed as a low-power CMOS component, it offers TTL/CMOS compatibility and can drive up to ten 74LS loads per tap.

Delay Lines IC Feature Summary

Delay Lines IC Procurement Notes

Verify the specific suffix designation against current manufacturer documentation to confirm lead-free status and package type. Confirm availability status as this component may be subject to discontinuation or limited supply constraints. Ensure environmental compliance requirements match the specific ordering code before procurement.

Delay Lines IC Selection Notes

Select the DS1100 series when fixed, equal-interval delays are required for multiple outputs. Choose the PDIP-8 variant for through-hole assembly processes. Verify that the 40ns total delay meets system timing requirements. Consider the 5V operation constraint and ensure the load capacity aligns with downstream logic gate requirements.

Delay Lines IC FAQ

How are the delays distributed across the five taps?

The delays are equally spaced. For the DS1100M-40+, the nominal delays at Taps 1 through 5 are 8ns, 16ns, 24ns, 32ns, and 40ns respectively.

What is the maximum input pulse width specification?

The minimum input pulse width (tWI) must be at least 20% of the Tap 5 delay time to ensure proper operation.

Does the device support both rising and falling edge accuracy?

Yes, the DS1100 is designed to reproduce both leading and trailing edges with equal precision.
