Product details
Overview
DS1100LZ-25+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 5ns (TAP 1), 10ns (TAP 2), 15ns (TAP 3), 20ns (TAP 4), and 25ns (TAP 5), operating from -40°C to +85°C in an 8-pin SO package. It reproduces both leading and trailing edges with equal precision and drives up to 10 74LS loads per tap, used in high-speed timing alignment and signal skew correction.
For engineers reviewing the DS1100LZ-25+ datasheet, DS1100LZ-25+ pinout, DS1100LZ-25+ application, or DS1100LZ-25+ equivalent, key selection factors include tap delay accuracy over temperature/voltage, TTL/CMOS compatibility, low-power CMOS operation, and industrial-grade reliability in surface-mount timing circuits.
Technical Context
The DS1100LZ-25+ implements a fully silicon-based delay architecture with five fixed, equally spaced delay taps referenced to a single input signal. Each tap delivers deterministic propagation delay with ±2ns tolerance (≤40ns delays) at +25°C/3.3V, and maintains monotonic delay variation across temperature and supply voltage.
It operates within a 3.0V–3.6V supply range and supports input pulse widths down to 20% of TAP 5 delay (i.e., ≥5ns for DS1100LZ-25+). Output rise/fall times are ≤2.5ns, and power-up time is 200μs - enabling use in synchronous digital systems requiring precise edge-aligned timing without external calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic families and stable delay performance across rail variation. |
| TAP 5 Delay | 25ns nominal - defines maximum fixed delay path for signal alignment or pipeline staging. |
| Delay Tolerance | ±2ns (≤40ns taps, +25°C/3.3V) - guarantees tight inter-tap skew control for phase-critical applications. |
| Output Drive | 8mA sink / -1mA source - sufficient to directly drive 10× 74LS loads without buffering. |
| Operating Temp | -40°C to +85°C - validated for industrial environments without derating or thermal compensation. |
| Rise/Fall Time | ≤2.5ns - preserves signal integrity in >200MHz digital interfaces with minimal edge distortion. |
| Power-Up Time | 200μs - enables reliable initialization in systems with controlled power sequencing. |
Pinout & Package
DS1100LZ-25+ is housed in an 8-pin SO (Small Outline) package, 150-mil width, RoHS-compliant and lead(Pb)-free. Pin layout follows standard SO-8 configuration with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input accepting TTL/CMOS-compatible signals; triggers all five delay paths simultaneously. |
| 2 | TAP 2 | Second delay output (10ns); provides intermediate timing reference for multi-stage synchronization. |
| 3 | TAP 4 | Fourth delay output (20ns); enables mid-range skew compensation without external delay elements. |
| 4 | GND | Digital ground reference; must be connected to system ground plane for noise immunity and delay stability. |
| 5 | TAP 5 | Fifth delay output (25ns); longest fixed delay path, used for maximum alignment offset or pipeline depth extension. |
| 6 | TAP 3 | Third delay output (15ns); central tap supporting balanced delay distribution in symmetric timing architectures. |
| 7 | TAP 1 | First delay output (5ns); shortest fixed delay, ideal for fine-grained jitter filtering or clock deskew. |
| 8 | VCC | +3.3V supply input; requires local 0.1μF ceramic decoupling adjacent to pin for AC noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay line | Eliminates hybrid or ceramic delay inconsistencies; ensures long-term stability and zero aging drift. |
| Equal-edge precision | Simultaneous leading/trailing edge reproduction enables accurate pulse-width preservation in delay chains. |
| Industrial temp support | Full electrical specification guaranteed from -40°C to +85°C - no derating required in embedded control systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-tap delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-20+ | Shorter max delay (20ns vs. 25ns); TAP 5 = 20ns; same 5-tap structure and SO-8 package. | Suitable where 5ns less total delay satisfies system timing budget; identical footprint and drive capability. | Select DS1100LZ-20+ if full 25ns delay is unnecessary and tighter delay granularity (4ns/tap) is preferred. |
| DS1100LZ-30+ | Longer max delay (30ns vs. 25ns); TAP 5 = 30ns; otherwise identical electrical and mechanical specs. | Required when system-level skew exceeds 25ns; retains same temperature stability and edge fidelity. | Choose DS1100LZ-30+ when board-level routing or component propagation adds >25ns cumulative delay needing compensation. |
Compared with DS1100LZ-20+ and DS1100LZ-30+, the DS1100LZ-25+ offers the optimal balance of delay range and tap spacing (5ns increments) for applications requiring precise 25ns alignment - avoiding under-compensation or excessive margin that increases signal path complexity.

FAQ
What is the nominal delay value for each tap of the DS1100LZ-25+?
The DS1100LZ-25+ provides five equally spaced nominal delays: TAP 1 = 5ns, TAP 2 = 10ns, TAP 3 = 15ns, TAP 4 = 20ns, and TAP 5 = 25ns. These values are specified at +25°C and VCC = 3.3V, with tolerances tightened to ±2ns for all taps under those conditions. The DS1100LZ-25+ achieves this via monolithic silicon delay elements, ensuring consistent tap-to-tap spacing without external components.
Does the DS1100LZ-25+ support both rising and falling edge delay accuracy?
Yes, the DS1100LZ-25+ is explicitly designed to reproduce both leading and trailing edges with equal precision. Its internal architecture guarantees matched tPLH (rising-edge delay) and tPHL (falling-edge delay) across all five taps, preserving pulse width integrity. This capability is confirmed in the device's General Description and AC Electrical Characteristics table, making DS1100LZ-25+ suitable for applications requiring accurate duty-cycle retention after delay insertion.
What is the recommended power supply decoupling for the DS1100LZ-25+?
A 0.1μF ceramic capacitor placed as close as possible to the VCC (pin 8) and GND (pin 4) pins is the minimum recommended decoupling for DS1100LZ-25+. This mitigates high-frequency supply noise that could modulate delay values or induce jitter. For systems with heavy switching loads, adding a bulk 4.7μF tantalum capacitor nearby further stabilizes the 3.3V rail. The DS1100LZ-25+ datasheet specifies active current (ICC) up to 10mA at 1MHz, confirming low-noise operation when properly decoupled.
Can the DS1100LZ-25+ drive standard TTL logic inputs directly?
Yes, the DS1100LZ-25+ can directly drive up to 10 × 74LS loads per tap, as stated in the General Description. Its output drive strength is specified as 8mA sink (IOL) and -1mA source (IOH) under worst-case VCC = 3.0V, meeting 74LS input current requirements (IIL ≤ 0.4mA, IIH ≤ 20μA). The DS1100LZ-25+ also features TTL-/CMOS-compatible input thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V), enabling seamless integration into mixed-logic systems without level-shifting.
Is the DS1100LZ-25+ RoHS-compliant and lead(Pb)-free?
Yes, the "+" suffix in DS1100LZ-25+ explicitly denotes a lead(Pb)-free and RoHS-compliant package, per Maxim's Ordering Information table. The device uses a standard 8-pin SO package (150-mil width) with matte tin lead finish, qualified for vapor-phase and infrared reflow soldering. The RoHS status is indicated solely by the "+" character in the part number - no additional markings are required, and the DS1100LZ-25+ meets EU Directive 2011/65/EU without exemptions.
