Product details
Overview
DS1100LZ-250/T&R from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 50ns, 100ns, 150ns, 200ns, and 250ns across TAP1–TAP5; features ±4ns delay tolerance over -40°C to +85°C, TTL/CMOS compatibility, and drives up to 10 × 74LS loads; used in digital timing alignment, clock deskew, and pulse-width adjustment circuits.
For engineers reviewing the DS1100LZ-250/T&R datasheet, DS1100LZ-250/T&R pinout, DS1100LZ-250/T&R application, or DS1100LZ-250/T&R equivalent, key selection considerations include tap-specific delay accuracy, industrial temperature operation, SO-8 package footprint, and 3.3V supply compliance without level-shifting.
Technical Context
The DS1100LZ-250/T&R implements an all-silicon delay architecture with five fixed, equally spaced delay taps referenced to a single input signal; each tap reproduces both leading and trailing edges with equal precision at the 1.5V logic threshold.
It operates from 3.0V to 3.6V, draws ≤10mA active current at 1MHz, and maintains delay stability across voltage and temperature via unidirectional drift behavior-i.e., all taps slow or speed together under varying conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with standard 3.3V logic rails without external regulation |
| Nominal Delays (TAP1–TAP5) | 50ns / 100ns / 150ns / 200ns / 250ns - enables precise multi-stage timing control in one device |
| Delay Tolerance (−40°C to +85°C) | ±4ns for ≤40ns taps; ±13% for >40ns taps - guarantees predictable skew margins in industrial environments |
| Output Drive Capability | Drives 10 × 74LS loads - supports direct fanout to legacy TTL logic without buffers |
| Input Logic Compatibility | TTL- and CMOS-compatible - accepts 0.8V/2.0V VIH/VIL thresholds, simplifying interface design |
| Package | 8-pin SO (150 mils) - industry-standard footprint with verified vapor-phase and IR solderability |
Pinout & Package
DS1100LZ-250/T&R is housed in an 8-pin SOIC (150 mils) package, RoHS-compliant, 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 simultaneously |
| 2 | TAP 2 | Second delay output (100ns); 1.5V threshold timing point; capable of driving 10 × 74LS loads |
| 3 | TAP 4 | Fourth delay output (200ns); matches TAP2 edge fidelity; same drive strength and loading specs |
| 4 | GND | Digital ground reference; must be low-impedance for stable delay accuracy and noise immunity |
| 5 | TAP 5 | Fifth delay output (250ns); longest delay tap; specified with ±13% tolerance over full temperature range |
| 6 | TAP 3 | Third delay output (150ns); center tap; exhibits identical delay drift behavior as TAP1–TAP5 |
| 7 | TAP 1 | First delay output (50ns); shortest delay; ±4ns tolerance at −40°C to +85°C |
| 8 | VCC | +3.3V supply; decoupling capacitor required at pin for AC timing stability |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates hybrid/ceramic delay line reliability risks and aging effects; enables 100% wafer-level testability |
| Equal-edge precision | Both rising and falling edges delayed identically - critical for pulse-width preservation in timing-critical paths |
| Unidirectional delay drift | All taps shift in same direction with temperature/voltage change - preserves inter-tap spacing integrity |
| SO-8 and µMAX packaging options | SO-8 (DS1100LZ) offers board-level compatibility and reflow robustness; µMAX (DS1100LU) saves area in space-constrained designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-250+ | Same electrical specs and SO-8 package; lead(Pb)-free/RoHS-compliant variant | No functional difference; required for EU/China RoHS-regulated production | Select DS1100LZ-250+ when environmental compliance is mandatory; otherwise DS1100LZ-250/T&R is functionally identical |
| DS1100LU-250/T&R | Identical delay values and timing specs; uses 8-pin µMAX (U8+1) package (3mm × 3mm vs SO-8's 4.9mm × 6.0mm) | Used where PCB area is constrained; requires different land pattern and reflow profile | Choose DS1100LU-250/T&R only when board space savings justify redesign; SO-8 remains preferred for manufacturability and thermal performance |
Compared with DS1100LZ-250+, the base DS1100LZ-250/T&R offers identical timing performance but lacks RoHS certification; versus DS1100LU-250/T&R, it trades compactness for easier assembly, better thermal dissipation (470.6mW vs 362mW), and broader reflow process margin.

FAQ
What is the operating temperature range for DS1100LZ-250/T&R?
The DS1100LZ-250/T&R is rated for continuous operation from −40°C to +85°C. This industrial temperature range is guaranteed per its Absolute Maximum Ratings and AC Electrical Characteristics tables, with delay tolerances fully specified across this span. All five taps exhibit correlated drift behavior within this range, preserving relative timing relationships. DS1100LZ-250/T&R does not support extended or military-grade temperature operation.
Does DS1100LZ-250/T&R require external decoupling capacitors?
Yes, DS1100LZ-250/T&R requires a local 0.1μF ceramic decoupling capacitor between VCC (pin 8) and GND (pin 4). The datasheet specifies that stable delay accuracy and low-noise operation depend on clean 3.3V supply rail integrity. Without proper decoupling, DS1100LZ-250/T&R may exhibit increased jitter, delay variation, or intermittent output glitches-especially at higher input frequencies or during fast edge transitions.
How many logic loads can each tap of DS1100LZ-250/T&R drive?
Each tap of DS1100LZ-250/T&R can drive up to 10 × 74LS logic inputs, as confirmed in the General Description section. This drive capability is maintained across the full operating temperature and voltage range (−40°C to +85°C, 3.0V–3.6V). Loading beyond this limit may degrade delay accuracy, increase propagation skew, or cause output voltage droop below valid logic thresholds.
Is DS1100LZ-250/T&R pin-compatible with other DS1100L variants?
Yes, DS1100LZ-250/T&R shares identical pinout and package (8-pin SO) with all DS1100LZ-xxx variants, including DS1100LZ-100/T&R and DS1100LZ-500/T&R. The only difference is nominal delay values per tap; electrical interface, supply, and timing behavior remain consistent. This allows drop-in replacement during prototyping or design iteration without PCB modification.
What is the meaning of "/T&R" in DS1100LZ-250/T&R?
The "/T&R" suffix in DS1100LZ-250/T&R denotes tape-and-reel packaging-standard for automated SMT placement. It indicates the device is supplied in a moisture-sensitive, ESD-safe reel format compatible with pick-and-place machines. DS1100LZ-250/T&R is not supplied in tube or tray formats; the "/T&R" does not affect electrical performance or specifications.
