Product details
Overview
DS1100LU-35+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line in an 8-pin µMAX package, delivering precisely spaced delays of 7ns, 14ns, 21ns, 28ns, and 35ns across taps 1–5. It reproduces both leading and trailing edges with ±4ns tolerance over –40°C to +85°C, drives up to 10 LS-TTL loads per tap, and operates with 3.0V–3.6V supply. It is used in high-speed timing alignment for clock skew correction and pulse-width modulation circuits.
For engineers reviewing the DS1100LU-35+ datasheet, DS1100LU-35+ pinout, DS1100LU-35+ application, or DS1100LU-35+ equivalent, key selection criteria include tap delay accuracy over temperature/voltage, TTL/CMOS compatibility, low-power CMOS operation, and µMAX footprint suitability for space-constrained PCBs.
Technical Context
The DS1100LU-35+ implements a monolithic all-silicon delay architecture-no hybrid or RC-based elements-ensuring stable, repeatable propagation delays across taps. Each output replicates the input logic state after its nominal delay (e.g., TAP 3 = 21ns), with matched rise/fall time (2.0–2.5ns) and edge fidelity maintained across full operating conditions.
Delay tolerance is specified as ±4ns for all taps at –40°C to +85°C (VCC = 3.0V–3.6V), and delays scale unidirectionally with temperature or voltage changes-no relative skew between taps. Input-to-output timing is measured at the 1.5V threshold, supporting precise edge-aligned signal conditioning in digital timing paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic systems and robust noise margin |
| Nominal Tap Delays | 7ns / 14ns / 21ns / 28ns / 35ns - fixed, equally spaced delays enabling predictable signal staging |
| Delay Tolerance | ±4ns over –40°C to +85°C - guarantees inter-tap consistency without recalibration |
| Output Drive | 8mA sink / –1mA source - sufficient to directly drive 10× 74LS loads without buffering |
| Rise/Fall Time | 2.0ns to 2.5ns - preserves signal integrity for >300MHz edge rates in high-speed logic |
| Power Dissipation | 362mW max at +70°C - enables reliable operation in thermally dense industrial layouts |
Pinout & Package
DS1100LU-35+ uses an 8-pin µMAX package (U8+1 outline, 90-0092 land pattern), measuring 3.0mm × 3.0mm × 0.8mm with gull-wing leads. The package supports vapor-phase and IR reflow soldering, including lead(Pb)-free profiles up to +260°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS-compatible signals (VIH ≥ 2.0V, VIL ≤ 0.8V) |
| 2 | TAP 2 | Second delay output (14ns); electrically identical to other taps, capable of driving 10× 74LS loads |
| 3 | TAP 4 | Fourth delay output (28ns); shares same AC/DC specs and load capability as TAP 2 |
| 4 | GND | Digital ground reference; must be low-impedance connection to minimize delay variation |
| 5 | TAP 5 | Fifth delay output (35ns); maximum delay tap; matches TAP 1–4 in edge accuracy and drive strength |
| 6 | TAP 3 | Third delay output (21ns); center tap; delay scales uniformly with temperature/voltage shifts |
| 7 | TAP 1 | First delay output (7ns); shortest fixed delay; enables fine-grained timing resolution |
| 8 | VCC | +3.3V supply; bypass capacitor (0.1µF ceramic) required within 5mm for stable delay performance |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay core | Eliminates aging drift and thermal hysteresis inherent in RC or analog delay methods |
| Equal tap spacing | Guarantees linear delay progression (7ns step) for uniform timing interpolation |
| Leading/trailing edge matching | Ensures symmetrical pulse-width preservation across all five outputs |
| Low-power CMOS design | Draws only 10mA typical at 1MHz - reduces thermal load in multi-device timing arrays |
| TTL-/CMOS-compatible I/O | Interfaces directly with legacy 74LS and modern 3.3V logic families without level-shifting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-35+ | Same electrical specs and delay values, but in 8-pin SO (150-mil) package instead of µMAX | Requires larger PCB area; better suited for manual assembly or prototyping boards with SO footprints | Select when SO package compatibility or thermal mass requirements outweigh space constraints |
| ON Semiconductor MC100EP195DG | Differential ECL inputs/outputs; 5-tap, but with 0.35ns resolution and ±0.15ns jitter; requires –3.3V supply | Targets ultra-low-jitter telecom clocking-not compatible with single-ended 3.3V logic systems | Choose only for ECL-based infrastructure where sub-ns precision and differential signaling are mandatory |
Compared with DS1100LZ-35+, the DS1100LU-35+ saves 60% board area while maintaining identical timing performance; versus MC100EP195DG, it offers plug-and-play 3.3V single-ended integration at the cost of picosecond-level jitter performance.

FAQ
What is the operating temperature range for DS1100LU-35+?
The DS1100LU-35+ is fully specified and tested over –40°C to +85°C. All delay tolerances (±4ns), DC parameters (e.g., VIH, VIL), and AC characteristics (tPLH/tPHL) are guaranteed across this industrial temperature range. No derating or external compensation is required for operation within these limits.
Does DS1100LU-35+ require external passive components to function?
No, DS1100LU-35+ operates autonomously with only a 0.1µF ceramic bypass capacitor placed near the VCC pin (Pin 8). No resistors, capacitors, or inductors are needed for basic delay functionality. The device draws current only during signal transitions, and its all-silicon core needs no calibration or trimming components.
Can DS1100LU-35+ drive standard 74LS logic directly?
Yes, DS1100LU-35+ can drive up to 10 LS-TTL loads per tap, verified under standard test conditions (VCC = 3.3V, TA = +25°C). Its output drive strength (IOL = 8mA, IOH = –1mA) meets 74LS input thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V), eliminating the need for buffer stages in most interface scenarios.
How does delay accuracy change with supply voltage variation?
Delay variation due to supply voltage (3.0V–3.6V) is included in the total ±4ns tolerance specification for DS1100LU-35+. All taps shift uniformly-no relative skew occurs-and the effect is fully characterized and guaranteed across the full operating range, per Note 2 in the datasheet.
Is DS1100LU-35+ pin-compatible with other DS1100L variants?
Yes, all DS1100LU-xxx variants-including DS1100LU-35+-share identical 8-pin µMAX pinout, electrical behavior, and thermal specifications. Only the nominal delay values differ (e.g., DS1100LU-25+ has 5ns/10ns/15ns/20ns/25ns taps), allowing direct substitution in layout when delay requirements change.
