Product details
Overview
DS1100LU-45+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 9ns (TAP 1), 18ns (TAP 2), 27ns (TAP 3), 36ns (TAP 4), and 45ns (TAP 5), operating across -40°C to +85°C. It reproduces both leading and trailing edges with equal precision, drives up to 10 × 74LS loads per tap, and uses low-power CMOS in an 8-pin µMAX package for high-density PCB layouts.
For engineers reviewing the DS1100LU-45+ datasheet, DS1100LU-45+ pinout, DS1100LU-45+ application, or DS1100LU-45+ equivalent, this device serves as a precise, all-silicon timing element for edge-aligned signal conditioning, clock deskew, and pulse-width control in industrial and embedded systems where hybrid delay lines are unsuitable.
Technical Context
The DS1100LU-45+ implements a fixed, tapped delay architecture using monolithic silicon-no external components or trimming required. Each tap delivers deterministic propagation delay referenced to the same input edge, with ±4ns tolerance over full temperature and voltage range (−40°C to +85°C, VCC = 3.0V–3.6V).
Its TTL-/CMOS-compatible inputs and outputs operate at 3.3V logic levels, with VIH ≥ 2.0V and VIL ≤ 0.8V, and support fast transitions (tRISE/tFALL ≤ 3.0ns). Output rise/fall times are 2.0–2.5ns, enabling use in sub-10ns timing windows without signal degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in modern 3.3V digital systems with ±10% rail tolerance |
| Nominal Delays (TAP 1–5) | 9ns / 18ns / 27ns / 36ns / 45ns - fixed, equally spaced delays enabling predictable multi-point signal sampling |
| Delay Tolerance | ±4ns (≤40ns taps) or ±13% (>40ns taps) over −40°C to +85°C - guarantees timing margin for synchronous edge alignment |
| Output Drive Strength | 8mA sink / −1mA source - sufficient to drive 10 × 74LS loads without external buffering |
| Input Pulse Width | ≥20% of TAP 5 delay (≥9ns) - sets minimum usable input pulse duration for reliable tap activation |
| Power-Up Time | 200μs - defines maximum delay before first valid output after power stabilization |
Pinout & Package
DS1100LU-45+ is housed in an 8-pin µMAX package (U8+1 outline, 3mm × 3mm body, 0.65mm pitch), compatible with vapor-phase and IR reflow soldering per RoHS-compliant lead-free process (+ suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS-compatible signals with 2.0V–3.6V high threshold |
| 2 | TAP 2 | Second delay output; delivers input signal delayed by 18ns with matched edge fidelity |
| 3 | TAP 4 | Fourth delay output; provides 36ns delay for mid-range timing interpolation |
| 4 | GND | Digital ground reference; must be low-impedance and decoupled near VCC pin |
| 5 | VCC | +3.3V supply; requires local 0.1μF ceramic decoupling capacitor |
| 6 | TAP 3 | Third delay output; 27ns delay enables symmetric tap spacing around center point |
| 7 | TAP 1 | First delay output; shortest path (9ns) for minimal latency sampling |
| 8 | TAP 5 | Fifth delay output; longest path (45ns) used for maximum delay window or pulse stretching |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates aging, thermal drift, and reliability issues associated with hybrid or LC-based delay lines |
| Equal-edge precision | Simultaneous leading- and trailing-edge delay matching ensures accurate pulse width preservation |
| Five equally spaced taps | Enables linear interpolation between delay points without external calculation or calibration |
| Low-power CMOS design | 10mA active current at 1MHz allows integration into power-constrained industrial controllers |
| RoHS-compliant µMAX package | 3mm × 3mm footprint saves >60% board area vs. SO-8 while maintaining full thermal performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay-line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-45+ | Same delay values and electrical specs, but in 8-pin SO-8 (S8+4) package - 4.9mm × 6.0mm vs. µMAX's 3.0mm × 3.0mm | Preferred where legacy SO-8 footprints exist or thermal dissipation >362mW is required | Select DS1100LZ-45+ when board space permits larger package or higher power handling is needed. |
| ON Semiconductor MC100EP195MNR4G | 5-tap ECL delay line with 0.35ns resolution, 3.3V supply, but requires negative bias and differential inputs/outputs | Suited for RF/microwave timing where sub-nanosecond resolution and jitter <0.1ps are critical | Choose MC100EP195MNR4G only for ultra-low-jitter ECL systems; not drop-in compatible with DS1100LU-45+. |
Compared with DS1100LZ-45+, the DS1100LU-45+ saves >60% PCB area while maintaining identical delay accuracy and drive strength; versus MC100EP195MNR4G, it offers simpler single-supply CMOS interfacing but trades off sub-ns resolution and ultra-low jitter.

FAQ
What is the operating temperature range for DS1100LU-45+?
The DS1100LU-45+ is fully specified and guaranteed over −40°C to +85°C. All delay tolerances, drive strength, and DC parameters are tested across this industrial temperature range, making DS1100LU-45+ suitable for deployment in harsh environments such as factory-floor controllers and outdoor test equipment without derating.
Does DS1100LU-45+ require external passive components for basic operation?
No, DS1100LU-45+ operates as a standalone delay element with no external resistors, capacitors, or inductors required. Only a 0.1μF ceramic decoupling capacitor on the VCC pin is recommended for noise suppression. The DS1100LU-45+ integrates all timing elements monolithically in silicon, eliminating tuning or calibration.
Can DS1100LU-45+ reproduce both rising and falling edges with identical delay?
Yes, DS1100LU-45+ is explicitly designed for equal leading- and trailing-edge accuracy. Both tPLH and tPHL are specified with identical tolerance bands (±4ns for TAP 1–5), ensuring pulse width integrity across all five outputs - a key differentiator from non-symmetric delay devices.
What is the maximum input frequency supported by DS1100LU-45+?
The DS1100LU-45+ supports input frequencies up to 1MHz under standard test conditions. At higher frequencies, ICC increases and delay accuracy may degrade due to layout sensitivity and decoupling limitations. For reliable operation above 1MHz, refer to the "Test Conditions" section in the DS1100LU-45+ datasheet and verify with actual board-level measurements.
Is DS1100LU-45+ pin-compatible with other DS1100L variants like DS1100LU-50+?
Yes, all DS1100LU-x variants share identical 8-pin µMAX pinout and electrical interface. Only the nominal delay values differ across the family (e.g., DS1100LU-45+ vs. DS1100LU-50+); no PCB or schematic changes are needed when substituting within the DS1100LU series for different delay requirements.
