DS1100U-20

Delay Lines IC Overview

The DS1100U-20 is a five-tap economy timing element manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced delays from 4ns to 500ns, with the -20 suffix specifying a total delay of 20ns (4ns per tap). The device operates on a single 5V supply within a voltage range of 4.75V to 5.25V. It utilizes low-power CMOS technology and features TTL/CMOS-compatible logic levels. The component is housed in an 8-pin µMAX surface-mount package and supports operation across commercial and industrial temperature ranges from -40°C to +85°C.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays
• Five taps equally spaced for accurate signal reproduction
• Designed to reproduce both leading and trailing edges with equal precision
• Low-power CMOS construction compatible with standard TTL and CMOS logic

Delay Lines IC Applications

• Signal processing requiring fixed time delays

Delay Lines IC Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and compliance status. The 'U' designation indicates the µMAX package, while '+' denotes lead-free/RoHS compliance. Confirm availability through authorized distributors as supply status may vary. Ensure the selected variant matches the required delay specifications and operating temperature range for your application.

Delay Lines IC Selection Notes

Select the DS1100U-20 when a total delay of 20ns with five equally spaced taps is required. This model is suitable for applications needing TTL/CMOS compatibility and low power consumption. Consider the µMAX package for space-constrained surface-mount designs. Verify that the input pulse width and frequency requirements fall within the specified AC electrical characteristics to maintain delay accuracy.

Delay Lines IC Part Context

The DS1100 series consists of silicon delay lines offering five taps with delays ranging from 4ns to 500ns. These devices are designed as low-cost replacements for hybrid technology timing elements.
