Product details
Overview
DS1100LU-25+T from Maxim Integrated is a 3.3V, 8-pin µMAX-packaged silicon delay line with five equally spaced taps delivering nominal delays of 5ns, 10ns, 15ns, 20ns, and 25ns. It reproduces both leading and trailing edges with equal precision, drives up to 10 LS-TTL loads per tap, and operates across -40°C to +85°C for industrial timing applications including clock skew correction and pulse shaping.
For engineers reviewing the DS1100LU-25+T datasheet, DS1100LU-25+T pinout, DS1100LU-25+T application, or DS1100LU-25+T equivalent, key selection factors include tap delay accuracy (±4ns over full temperature range), 3.3V CMOS/TTL compatibility, low-power operation (10mA typical ICC), and µMAX package footprint constraints for high-density PCB layouts.
Technical Context
The DS1100LU-25+T implements an all-silicon delay architecture with fixed, monotonic delay progression across five output taps-no external components or configuration required. Each tap replicates the input logic state after its specified delay, with matched tPLH and tPHL characteristics ensuring symmetrical edge fidelity.
Delay tolerance is specified as ±4ns (for ≤40ns delays) over -40°C to +85°C at 3.3V, and all taps track unidirectionally with voltage/temperature changes-eliminating relative skew between outputs. Input-to-output propagation is measured at the 1.5V threshold with 50Ω source impedance and <3ns input rise/fall times.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in 3.3V systems with ±10% rail tolerance |
| Nominal Tap Delays | 5ns / 10ns / 15ns / 20ns / 25ns - fixed, factory-trimmed delays enabling precise pulse spacing without calibration |
| Delay Tolerance | ±4ns over -40°C to +85°C - guarantees absolute timing margin for synchronous signal alignment |
| Output Drive Strength | 8mA sink / -1mA source - sufficient to drive 10x 74LS loads without external buffering |
| Input Capacitance | 5–10pF - minimizes loading on upstream drivers and preserves signal integrity at high frequencies |
| Power-Up Time | 200μs - defines minimum reset-to-valid-output latency after VCC stabilization |
Pinout & Package
DS1100LU-25+T uses an 8-pin µMAX package (U8+1 outline, 3mm × 3mm body, 0.65mm pitch), optimized for space-constrained industrial PCBs. The package is RoHS-compliant (lead-free), vapor-phase and IR solderable, and features exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended TTL/CMOS-compatible input; accepts 0.8V/2.0V logic thresholds |
| 2 | TAP 2 | Second delay output (10ns); electrically identical to other taps, capable of driving 10 LS loads |
| 3 | TAP 4 | Fourth delay output (20ns); shares same output structure and timing spec as TAP 2 |
| 4 | GND | Digital ground reference; must be connected to system ground plane for noise immunity |
| 5 | TAP 5 | Fifth delay output (25ns); highest-delay tap, used for maximum offset or synchronization window extension |
| 6 | TAP 3 | Third delay output (15ns); central tap for symmetric delay interpolation or mid-point sampling |
| 7 | TAP 1 | First delay output (5ns); lowest-latency tap for minimal skew correction or fast feedback paths |
| 8 | VCC | +3.3V supply; requires local 0.1μF ceramic decoupling adjacent to pin |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-25+ | 8-pin SOIC package (150 mils), larger footprint (4.9mm × 3.9mm), same electrical specs and delay values | Better thermal dissipation and hand-solderability; unsuitable for ultra-dense layouts | Select DS1100LZ-25+ when board assembly uses wave soldering or requires higher mechanical robustness |
| ON Semiconductor MC100EP195DG | Differential ECL inputs/outputs, 3.3V supply, 5-tap, but with ±10% delay tolerance (vs. ±4ns absolute) and higher power (35mA ICC) | Requires level translation for single-ended systems; suited for RF/datacom clock trees, not general-purpose logic | Select MC100EP195DG only for differential signaling environments requiring sub-100ps jitter performance |
Compared with DS1100LZ-25+, the DS1100LU-25+T saves 58% PCB area but trades off thermal headroom; versus MC100EP195DG, it offers tighter absolute delay tolerance and lower power at the cost of single-ended I/O and reduced frequency scalability.

FAQ
What is the operating voltage range for DS1100LU-25+T?
The DS1100LU-25+T operates from 3.0V to 3.6V, making it compatible with standard 3.3V logic rails. Its internal circuitry is characterized across this full range, and all timing specifications-including tap delays and tolerances-are guaranteed within these limits. Operation outside this range may result in undefined behavior or damage, as absolute maximum ratings cap pin voltage at -0.5V to +6.0V relative to ground.
Does DS1100LU-25+T support both rising and falling edge delays?
Yes, DS1100LU-25+T reproduces both leading and trailing edges with equal precision. Its tPLH (rising edge delay) and tPHL (falling edge delay) are matched and specified identically across all five taps. This symmetry ensures preserved pulse width and duty cycle integrity-critical for applications like PWM dead-time generation and clock deskewing where edge fidelity directly impacts system reliability.
What is the maximum capacitive load each tap of DS1100LU-25+T can drive?
Each tap of DS1100LU-25+T is rated to drive up to 10 LS-TTL loads, equivalent to approximately 10 × 20pF = 200pF total load capacitance under standard test conditions. Driving heavier loads will increase output rise/fall times and may degrade delay accuracy beyond ±4ns. For loads exceeding this, buffer amplifiers such as 74LVC1G125 should be used to maintain timing integrity.
Is DS1100LU-25+T pin-compatible with other DS1100L variants?
DS1100LU-25+T shares identical pinout and functionality with all DS1100LU-x variants (e.g., DS1100LU-50+T), differing only in nominal delay values. However, it is not pin-compatible with DS1100LZ-x (SOIC) versions despite identical pin numbering-the µMAX and SO packages have different physical dimensions and land patterns. Board redesign is required when switching between U and Z suffixes.
How does temperature affect delay accuracy in DS1100LU-25+T?
Temperature affects DS1100LU-25+T delay uniformly across all taps: all five outputs slow down or speed up together with temperature change, preserving relative spacing. Over -40°C to +85°C, absolute delay tolerance is ±4ns for the 25ns tap (TAP 5), and ±4ns applies to all taps ≤40ns. This unidirectional tracking eliminates inter-tap skew, simplifying timing analysis in thermally varying environments like motor control enclosures.
