Product details
Overview
DS1100LU-100+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line in µMAX-8 package delivering precisely spaced delays of 20ns, 40ns, 60ns, 80ns, and 100ns at the five output taps. It reproduces both leading and trailing edges with equal precision, supports TTL/CMOS logic levels, and drives up to 10 LS loads per tap. Used in high-speed timing alignment, clock skew correction, and pulse-width adjustment circuits.
For engineers reviewing the DS1100LU-100+ datasheet, DS1100LU-100+ pinout, DS1100LU-100+ application, or DS1100LU-100+ equivalent, key selection factors include guaranteed ±4ns delay tolerance over –40°C to +85°C, 3.0V–3.6V supply operation, 2.5ns max output rise/fall time, and µMAX-8 footprint compatibility with space-constrained PCB layouts.
Technical Context
The DS1100LU-100+ implements an all-silicon delay architecture with fixed, equally spaced propagation paths-no external components or trimming required. Each tap provides deterministic, temperature- and voltage-stable delay with unidirectional drift behavior: if one tap slows, all slow proportionally.
It operates as a passive signal replicator-not a programmable or adjustable delay-but achieves precise edge-aligned timing via monolithic CMOS delay elements. Input-to-output propagation is measured at the 1.5V threshold for both rising (tPLH) and falling (tPHL) transitions, ensuring matched edge fidelity across all five outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - Enables direct integration into 3.3V logic systems without level-shifting. |
| Nominal Delays (TAP1–TAP5) | 20ns / 40ns / 60ns / 80ns / 100ns - Fixed, equally spaced delays for multi-point timing alignment. |
| Delay Tolerance (–40°C to +85°C) | ±4ns for ≤40ns delays; ±13% for >40ns delays - Guarantees predictable timing margin under industrial conditions. |
| Output Drive Strength | 8mA sink / –1mA source - Sufficient to drive 10x 74LS loads without external buffering. |
| Input/Output Threshold | 1.5V switching point - Matches standard TTL/CMOS logic thresholds for reliable interfacing. |
| Rise/Fall Time | 2.0ns to 2.5ns - Supports clean edge integrity in sub-5ns timing-critical paths. |
| Power-Up Time | 200μs - Ensures stable delay behavior after power application; no initialization sequence needed. |
Pinout & Package
DS1100LU-100+ uses the 8-pin µMAX package (U8+1 outline), measuring 3.0mm × 3.0mm × 0.8mm with exposed thermal pad. This lead(Pb)-free, RoHS-compliant package supports vapor-phase and IR reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS-compatible signals with 50Ω source impedance. |
| 2 | TAP 2 | Second delayed output; delivers input signal delayed by 40ns with matched edge fidelity. |
| 3 | TAP 4 | Fourth delayed output; delivers input signal delayed by 80ns; electrically identical to other taps. |
| 4 | GND | Analog/digital ground reference; must be low-impedance and decoupled near VCC pin. |
| 5 | TAP 5 | Fifth delayed output; delivers input signal delayed by 100ns; maximum delay in this variant. |
| 6 | TAP 3 | Third delayed output; delivers input signal delayed by 60ns; center tap for symmetric delay trees. |
| 7 | TAP 1 | First delayed output; delivers input signal delayed by 20ns; lowest-latency tap for fine-grained timing. |
| 8 | VCC | +3.3V supply; requires local 0.1μF ceramic decoupling capacitor placed adjacent to pin. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-100+ | SO-8 package (5.0mm × 4.0mm); same electrical specs and delay values. | Preferred where board real estate allows larger footprint and hand-soldering or legacy assembly is used. | Select DS1100LZ-100+ when µMAX-8 placement or thermal management is impractical. |
| ON Semiconductor MC100EP195DG | Differential ECL inputs/outputs; 3.3V supply; 0.35ns typical delay resolution; higher power (35mA ICC). | Suitable for ultra-low-jitter, high-frequency (>1GHz) applications where single-ended delay precision is insufficient. | Choose MC100EP195DG only when differential signaling, sub-1ns delay granularity, or ECL interface compatibility is required. |
Compared with DS1100LZ-100+, DS1100LU-100+ saves >60% PCB area but requires tighter reflow profile control; compared with MC100EP195DG, DS1100LU-100+ offers lower power, simpler interfacing, and lower cost-but lacks differential noise immunity and sub-nanosecond resolution.

FAQ
What is the operating voltage range for DS1100LU-100+?
The DS1100LU-100+ operates over a supply voltage range of 3.0V to 3.6V. It is specified and tested at 3.3V ±0.1V for timing parameters, and its DC characteristics-including VIH, VIL, and ICC-are guaranteed across the full 3.0V–3.6V range. Operation outside this range may result in undefined timing behavior or damage.
Does DS1100LU-100+ support both rising and falling edge delays?
Yes, DS1100LU-100+ guarantees matched delay accuracy for both rising (tPLH) and falling (tPHL) edges across all five taps. The datasheet specifies identical tolerance bands for both transitions, and the device reproduces input edge polarity with equal precision-critical for preserving pulse width in delay chains.
Can DS1100LU-100+ drive standard TTL logic directly?
Yes, DS1100LU-100+ can drive up to 10 LS-TTL loads per tap, with IOL = 8mA and IOH = –1mA at VCC = 3.0V. Its output voltage levels meet TTL-compatible thresholds (VOH ≥ 2.3V, VOL ≤ 0.5V), and its 1.5V switching point aligns with standard TTL logic families-no level-shifter required.
What is the delay tolerance of DS1100LU-100+ over temperature?
Over the full industrial range (–40°C to +85°C), DS1100LU-100+ has a delay tolerance of ±4ns for TAP1 (20ns) and TAP2 (40ns), and ±13% for TAP3 (60ns), TAP4 (80ns), and TAP5 (100ns). This reflects the datasheet's distinction between absolute ns tolerance for shorter delays and percentage tolerance for longer ones.
Is DS1100LU-100+ RoHS-compliant and lead(Pb)-free?
Yes, DS1100LU-100+ is RoHS-compliant and lead(Pb)-free, as indicated by the "+" suffix in the part number. It meets JEDEC J-STD-020 reflow requirements for lead-free soldering (peak temperature +260°C), and its µMAX-8 package (U8+1) carries official RoHS certification per Maxim Integrated documentation.
