Product details
Overview
DS1100LZ-125+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 25ns, 50ns, 75ns, 100ns, and 125ns across TAP1–TAP5; it operates from −40°C to +85°C, supports TTL/CMOS-compatible inputs, and drives up to 10 × 74LS loads per tap in an 8-pin SO package.
For engineers reviewing the DS1100LZ-125+ datasheet, DS1100LZ-125+ pinout, DS1100LZ-125+ application, or DS1100LZ-125+ equivalent, this page delivers verified timing accuracy, edge-preserving delay behavior, tap-specific tolerance specs, industrial temperature support, and SO-package layout compatibility for signal synchronization in high-speed digital systems.
Technical Context
The DS1100LZ-125+ implements a monolithic all-silicon delay architecture with fixed, equally spaced taps-no external components or clock required. Each tap reproduces both leading and trailing edges with matched precision, and delay tolerances are specified as ±4ns (≤40ns taps) or ±13% (>40ns taps) over −40°C to +85°C.
It uses low-power CMOS logic, draws ≤10mA active current at 1MHz, and maintains stable delay performance across VCC = 3.0V–3.6V. Input pulse width must be ≥20% of Tap 5 delay (≥25ns), and output rise/fall times are ≤2.5ns under standard test load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic domains without level-shifting. |
| Nominal Delays (TAP1–TAP5) | 25ns / 50ns / 75ns / 100ns / 125ns - enables precise multi-stage timing alignment in serial data paths or clock skew correction. |
| Delay Tolerance (TAP5) | ±13% over −40°C to +85°C - defines worst-case timing margin for system-level setup/hold analysis. |
| Output Drive Strength | 8mA sink / −1mA source - sufficient to drive 10 × 74LS loads without external buffering. |
| Input Compatibility | TTL- and CMOS-compatible VIH ≥2.0V, VIL ≤0.8V - allows direct interfacing with legacy and modern logic families. |
| Power-Up Time | 200μs - guarantees stable delay operation within microseconds after supply stabilization. |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade embedded and communications equipment. |
Pinout & Package
DS1100LZ-125+ is housed in an 8-pin SO (Small Outline) package, 150-mil width, RoHS-compliant and lead(Pb)-free. Pin 1 is IN, pins 2–5 are TAP2–TAP5, pin 6 is TAP3, pin 7 is TAP1, and pin 8 is VCC; GND occupies pin 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Signal Input | Accepts TTL/CMOS logic pulses; triggers all five delay taps simultaneously. |
| TAP2 (Pin 2) | Delay Output | Delivers input signal delayed by 50ns; electrically identical to other taps but phase-shifted. |
| TAP4 (Pin 3) | Delay Output | Delivers input signal delayed by 100ns; usable for intermediate timing points in pipeline stages. |
| GND (Pin 4) | Ground Reference | Common return path for all I/O and power; requires low-impedance PCB connection to minimize noise coupling. |
| TAP5 (Pin 5) | Delay Output | Delivers input signal delayed by 125ns; longest fixed delay in the series, used for maximum skew compensation. |
| TAP3 (Pin 6) | Delay Output | Delivers input signal delayed by 75ns; central tap enabling symmetric delay distribution around mid-point. |
| TAP1 (Pin 7) | Delay Output | Delivers input signal delayed by 25ns; shortest delay for fine-grained timing adjustments. |
| VCC (Pin 8) | Power Supply | +3.3V supply rail; requires local 0.1μF ceramic decoupling adjacent to pin for AC stability. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates hybrid or ceramic delay line reliability risks and enables full CMOS process control for consistent parametric yield. |
| Equal-edge precision (leading & trailing) | Preserves pulse width integrity across all taps-critical for clock/data recovery and eye-diagram-sensitive interfaces. |
| Five fixed, equally spaced taps | Provides deterministic delay ladder without configuration overhead-ideal for hardware-based timing calibration and skew tuning. |
| Industrial temperature qualification | Validated operation from −40°C to +85°C ensures robustness in base stations, motor controllers, and factory automation. |
| SO and µMAX package options | 8-pin SO variant (DS1100LZ-125+) offers standard surface-mount compatibility; µMAX version enables ultra-compact layouts. |

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+ | Shorter max delay (100ns vs. 125ns); TAP5 = 100ns instead of 125ns. | Suitable where total skew budget is ≤100ns; not interchangeable if 125ns delay is required. | Select DS1100LZ-100+ only when system timing margin permits reduced maximum delay. |
| DS1100LZ-150+ | Longer max delay (150ns vs. 125ns); TAP5 = 150ns; same tap spacing ratio (1:2:3:4:5). | Used when greater skew compensation range is needed; may require layout revalidation due to longer delay path. | Choose DS1100LZ-150+ if design requires >125ns alignment headroom or future-proofing against board-level drift. |
Compared with DS1100LZ-125+, DS1100LZ-100+ reduces maximum alignment capability by 25ns but retains identical tap resolution and drive strength, while DS1100LZ-150+ extends that capability by 25ns with no change in interface or power behavior-both share the same SO package, temperature rating, and edge-fidelity performance.
