DS1100LU-20+

Delay Lines IC Overview

The DS1100LU-20+ is a 3.3V tapped delay line from the DS1100L series, characterized for operation between 3.0V and 3.6V. It provides five equally spaced taps with a total nominal delay of 20ns. The device features tap delays of 4ns, 8ns, 12ns, 16ns, and 20ns, with a tap increment of 4ns. It operates within an industrial temperature range of -40°C to +85°C and utilizes an 8-pin µMAX surface-mount package.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays
• Five equally spaced taps reproducing both leading and trailing edges with equal precision
• Low-power CMOS technology compatible with TTL and CMOS logic levels

Delay Lines IC Applications

• Timing element applications requiring fixed delay intervals
• Pulse width modulation circuits
• Clock distribution networks

Delay Lines IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free packaging specifications. Ensure the ordering suffix matches the required tape-and-reel or tube configuration. Validate that the specific part number corresponds to the intended delay value and package type before finalizing procurement orders.

Delay Lines IC Selection Notes

Select this component when a 3.3V supply voltage is required instead of the standard 5V variant. Choose the DS1100LU-20+ specifically for its 20ns total delay and 4ns tap increments. Consider the µMAX package for space-constrained printed circuit board layouts. Verify that the input pulse width requirements align with the specified minimums in the electrical characteristics table.

Delay Lines IC Part Context

This component belongs to the DS1100L family, which serves as the 3.3V version of the DS1100 series. The 'LU' designation indicates the use of the µMAX surface-mount package. The '-20+' suffix specifies the 20ns total delay duration and lead-free/RoHS-compliant manufacturing process.

Delay Lines IC FAQ

What is the delay tolerance for the DS1100LU-20+?

For delays less than or equal to 40ns, the input-to-tap delay tolerance is ±2ns at +25°C, ±3ns over 0°C to +70°C, and ±4ns over -40°C to +85°C.

How many loads can each tap drive?

Each tap is capable of driving up to ten 74LS loads.

Is the delay programmable?

No, the DS1100LU-20+ is a fixed-delay tapped delay line. Custom intermediate delay values are available only on a special order basis.
