DS1100M-20+

Delay Lines IC Overview

The DS1100M-20+ is a five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced taps with delays ranging from 4ns to 500ns, specifically offering a total delay of 20ns for this model. The device operates on a single 5V supply within a voltage range of 4.75V to 5.25V. It features low-power CMOS technology and is TTL/CMOS compatible. Each tap can drive up to ten 74LS loads. The component is housed in an 8-PDIP package and supports through-hole mounting. It functions reliably across an operating temperature range of -40°C to +85°C.

Delay Lines IC Procurement Notes

Verify the specific ordering suffix to confirm package type and compliance status. The '+' suffix indicates a lead-free/RoHS-compliant package. Confirm availability as the product lifecycle status may be discontinued or limited. Ensure the selected variant matches the required delay value and operating temperature range for your design specifications.

Delay Lines IC Selection Notes

Select the DS1100 series based on the required total delay time indicated by the part number suffix. Choose the appropriate package style, such as PDIP for through-hole or SO/µMAX for surface mount, depending on PCB layout constraints. Verify that the supply voltage remains within the specified 4.75V to 5.25V range to maintain accurate delay tolerances across the industrial temperature spectrum.

Delay Lines IC Part Context

The DS1100 series serves as an improved replacement for the older DS1000 family. It utilizes industry-standard packaging to save PC board area while maintaining low cost. The series includes various delay options from 20ns to 500ns, allowing designers to choose exact timing increments without custom programming. This economy timing element simplifies circuit design by eliminating the need for complex discrete delay components.

Delay Lines IC Replacement Considerations

The datasheet identifies the DS1100 series as an improved replacement for the DS1000. Designers should verify pin compatibility and electrical characteristics when substituting these parts. Custom delays are available upon request from the manufacturer if standard tap values do not meet specific application requirements.
