DS1100U-125+

Delay Lines IC Overview

The DS1100U-125+ is a five-tap silicon delay line in an 8-pin µMAX package. It provides equally spaced delays of 25ns, 50ns, 75ns, 100ns, and 125ns at Taps 1 through 5. Operating on a single 5V supply (4.75V to 5.25V), it features low-power CMOS technology with TTL/CMOS compatibility. The device ensures stable timing with input-to-tap delay tolerances of ±2ns for delays up to 40ns and ±5% for longer delays at +25°C. It operates within a temperature range of -40°C to +85°C and can drive up to ten 74LS loads per tap.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing superior reliability over hybrid technology
• Five taps equally spaced for precise leading- and trailing-edge reproduction
• Low-power CMOS construction compatible with standard TTL and CMOS logic levels

Delay Lines IC Applications

• Timing element replacement for legacy DS1000 series devices
• Precision pulse generation and signal synchronization circuits
• Digital logic timing adjustments requiring fixed propagation delays

Delay Lines IC Procurement Notes

Verify the specific suffix 'U' corresponds to the µMAX surface-mount package and '+125' indicates the 125ns nominal delay configuration. Confirm RoHS compliance status via the '+' designation. Ensure the operating environment remains within the specified -40°C to +85°C industrial temperature range to maintain guaranteed delay accuracy specifications.

Delay Lines IC Selection Notes

Select this component when a fixed 125ns maximum delay with intermediate taps is required in a compact surface-mount footprint. Compare against the DS1100LZ-125+ if a 3.3V supply voltage is necessary instead of the standard 5V operation. Consider custom delay variants if non-standard tap intervals are needed for specific application requirements.

Delay Lines IC Part Context

This part belongs to the DS1100 series of economy timing elements designed as direct replacements for older hybrid delay lines. The U suffix identifies the 8-pin µMAX package variant, distinct from the SOIC package version (DS1100Z). The series offers various delay extensions ranging from 4ns to 500ns to accommodate different timing precision needs.

Delay Lines IC FAQ

How does the delay tolerance vary with temperature?

For delays greater than 40ns, the input-to-tap delay tolerance increases from ±5% at +25°C to ±13% across the full -40°C to +85°C operating temperature range.

What is the driving capability of each tap output?

Each tap output is capable of driving up to ten 74LS loads without degradation of signal integrity or timing performance.

Are intermediate delay values available between the standard taps?

Standard parts provide five equally spaced taps. Intermediate delay values are available only on a custom basis by contacting the manufacturer directly.
