Product details
Overview
DS1100LZ-125/T&R 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; features ±4ns delay tolerance over –40°C to +85°C, TTL/CMOS-compatible inputs/outputs, and drives up to 10 × 74LS loads per tap; used in digital timing alignment, clock skew correction, and pulse-width adjustment in industrial control and test equipment.
For engineers reviewing the DS1100LZ-125/T&R datasheet, DS1100LZ-125/T&R pinout, DS1100LZ-125/T&R application, or DS1100LZ-125/T&R equivalent, key selection criteria include tap-specific delay accuracy, 3.3V supply compatibility, SO-8 package footprint, leading/trailing edge fidelity, and industrial temperature operation without derating.
Technical Context
The DS1100LZ-125/T&R implements a monolithic all-silicon delay architecture with five fixed, equally spaced delay taps-no external components or trimming required. Each tap reproduces both rising and falling edges with matched propagation characteristics, enabling precise edge-aligned signal replication.
It operates exclusively from a 3.0V–3.6V supply, delivers output rise/fall times ≤2.5ns, and maintains delay stability across voltage (±13% for delays >40ns) and temperature (–40°C to +85°C). Input-to-tap delay tolerances are specified per tap group and condition, with TAP1–TAP3 having tighter initial tolerance than TAP4–TAP5 in the -75 variant-but DS1100LZ-125/T&R uses the standard tolerance profile per Table 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Delays (TAP1–TAP5) | 25ns / 50ns / 75ns / 100ns / 125ns - fixed, factory-trimmed delays enabling deterministic signal offset without calibration |
| Supply Voltage Range | 3.0V to 3.6V - compatible with modern 3.3V logic systems; no level-shifting needed |
| Delay Tolerance (–40°C to +85°C) | ±4ns for delays ≤40ns; ±13% for delays >40ns - ensures predictable timing margin in wide-temp industrial environments |
| Output Drive Capability | 8mA sink / –1mA source - sufficient to directly drive 10 × 74LS loads per tap without buffering |
| Input/Output Compatibility | TTL- and CMOS-compatible - interoperable with legacy and modern logic families without interface circuitry |
| Rise/Fall Time | ≤2.5ns - supports clean edge integrity at >100MHz input frequencies |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded and instrumentation applications |
Pinout & Package
DS1100LZ-125/T&R is supplied in an 8-pin SO (Small Outline, 150-mil width) package, RoHS-compliant and tape-and-reel packaged for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS levels; triggers all five delay taps synchronously |
| 2 | TAP 2 | Second delay output; delivers input signal delayed by 50ns; electrically identical to other taps |
| 3 | TAP 4 | Fourth delay output; delivers input signal delayed by 100ns; rated for same load and timing specs as TAP2 |
| 4 | GND | Digital ground reference; must be low-impedance connection to minimize delay variation and noise coupling |
| 5 | TAP 5 | Fifth delay output; delivers input signal delayed by 125ns; highest-delay tap in this variant |
| 6 | TAP 3 | Third delay output; delivers input signal delayed by 75ns; center tap for symmetric delay distribution |
| 7 | TAP 1 | First delay output; delivers input signal delayed by 25ns; shortest fixed delay in DS1100LZ-125/T&R |
| 8 | VCC | +3.3V power supply; requires local 0.1µF ceramic decoupling adjacent to pin for stable delay performance |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates hybrid or ceramic delay lines-enables 100% wafer-level testing, superior long-term stability, and no aging drift |
| Leading- and trailing-edge matching | Ensures symmetrical delay for both signal edges-critical for pulse-width preservation and duty-cycle-sensitive circuits |
| Five equally spaced taps | Provides discrete, calibrated timing offsets in one device-reduces board space vs. multiple discrete delay elements |
| Industrial temperature qualification | Guaranteed operation from –40°C to +85°C without derating-supports deployment in harsh environmental conditions |
| Vapor-phase and IR solderable | Compatible with standard reflow profiles including Pb-free (260°C) and SnPb (240°C)-simplifies manufacturing integration |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1023-125+ (Maxim) | 3.3V 8-tap delay line; nominal delays 12.5ns–125ns; ±3% tolerance; SO-16 package | Higher tap count and finer delay resolution; larger footprint and higher cost | Select when sub-25ns incremental delays or >5 tap points are required; not pin-compatible |
| 74LVC1G125SE-7 (Diodes Inc.) | Single-channel 3.3V buffer with 2.8ns typical propagation delay; no multi-tap capability; SOT-353 package | Only provides single fixed delay; no internal tap structure; requires external RC or transmission-line delay for multi-offset use | Select only for simple single-delay buffering; not a functional substitute for multi-tap timing alignment |
Compared with DS1100LZ-125/T&R, DS1023-125+ offers more taps and tighter % tolerance but demands PCB real estate and layout changes, while 74LVC1G125SE-7 lacks tap architecture entirely-making DS1100LZ-125/T&R the sole solution for compact, calibrated, multi-point delay generation in industrial timing systems.

FAQ
What is the maximum operating frequency supported by DS1100LZ-125/T&R?
The DS1100LZ-125/T&R does not specify a maximum operating frequency, but its input pulse width (tWI) must be ≥20% of the TAP5 delay (i.e., ≥25ns for DS1100LZ-125/T&R), implying a practical upper limit near 20MHz for reliable tap activation. Higher frequencies may cause degraded delay accuracy due to layout and decoupling sensitivity, as noted in datasheet Note 9.
Is DS1100LZ-125/T&R pin-compatible with earlier DS1100 versions?
No-DS1100LZ-125/T&R uses the same SO-8 pinout as the DS1100L series, but differs from the original 5V DS1100 (which uses different VCC/GND placement and voltage ratings). The DS1100LZ-125/T&R is not electrically or mechanically compatible with non-L variants due to 3.3V-only operation and revised absolute maximum ratings.
Can DS1100LZ-125/T&R drive 50Ω transmission lines directly?
No-DS1100LZ-125/T&R is designed to drive logic loads (up to 10 × 74LS), not 50Ω coaxial lines. Its output impedance is not controlled, and driving 50Ω loads will distort rise/fall times and degrade delay accuracy. Use a dedicated line driver (e.g., MAX9110) if transmission-line interfacing is required.
Does DS1100LZ-125/T&R require external decoupling capacitors?
Yes-per the datasheet test conditions and layout guidance, a 0.1µF ceramic capacitor must be placed as close as possible to the VCC pin (Pin 8) and GND (Pin 4) to ensure stable delay performance and minimize supply-induced jitter. Omitting this capacitor risks increased delay variation and edge distortion.
Are the delays of DS1100LZ-125/T&R monotonic across temperature and voltage?
Yes-the DS1100LZ-125/T&R exhibits unidirectional delay variation: all taps slow down or speed up together with temperature or supply voltage changes (Note 3). For example, if TAP1 delay increases at high temperature, TAP5 also increases proportionally-preserving relative spacing and enabling predictable system-level timing margining.
