Product details
Overview
DS1100LZ-250+T 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. It operates from 3.0V to 3.6V over –40°C to +85°C, reproduces both leading and trailing edges with ±4ns tolerance (–40°C to +85°C), and drives up to 10 LS-TTL loads per tap. Used in high-speed timing alignment for test equipment and digital signal synchronization.
For engineers reviewing the DS1100LZ-250+T datasheet, DS1100LZ-250+T pinout, DS1100LZ-250+T application, or DS1100LZ-250+T equivalent, key selection criteria include tap delay precision across temperature, edge fidelity for pulse-width integrity, TTL/CMOS compatibility, SO-8 package footprint, and industrial-grade supply voltage stability.
Technical Context
The DS1100LZ-250+T implements a monolithic all-silicon delay architecture-no hybrid or ceramic components-ensuring stable propagation delay vs. temperature and voltage. Each of its five taps delivers fixed, equally spaced delays referenced to the input signal's 1.5V crossing point, with identical tPLH and tPHL tolerances.
Delay accuracy is specified as ±4ns (for ≤40ns taps) or ±13% (for >40ns taps) over –40°C to +85°C at VCC = 3.0V–3.6V. Input-to-output timing is measured under controlled 50Ω source impedance, 3ns max rise/fall time, and 500ns input pulse width per test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic systems and margin against rail droop in dense PCB layouts |
| Nominal Tap Delays | 50ns / 100ns / 150ns / 200ns / 250ns - enables precise multi-point signal staging for skew correction and pipeline alignment |
| Delay Tolerance (TAP5) | ±13% over –40°C to +85°C - defines worst-case timing budget for synchronous sampling circuits |
| Input Pulse Width | 500ns minimum - sets minimum valid signal duration for reliable tap activation without pulse truncation |
| Output Drive Strength | 8mA sink / –1mA source - supports direct interfacing to 74LS-family inputs without external buffering |
| Power-Up Time | 200μs - determines minimum reset-to-valid-output latency after power stabilization |
Pinout & Package
DS1100LZ-250+T is housed in an 8-pin SOIC (150-mil) package with gull-wing leads, RoHS-compliant and vapor-phase/IR solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended CMOS/TTL-compatible input; accepts 0.8V/2.0V logic thresholds |
| 2 | TAP 2 | Second delayed output (100ns); electrically identical to TAP1–TAP5, rated for 10 LS loads |
| 3 | TAP 4 | Fourth delayed output (200ns); matches TAP2 in drive capability and edge fidelity |
| 4 | GND | Digital ground reference; must be low-impedance and decoupled near VCC pin |
| 5 | TAP 5 | Fifth delayed output (250ns); maximum delay tap, same delay tolerance spec as other taps |
| 6 | TAP 3 | Third delayed output (150ns); center tap for symmetric delay interpolation |
| 7 | TAP 1 | First delayed output (50ns); shortest delay, ±4ns absolute tolerance over full temp range |
| 8 | VCC | +3.3V supply; requires local 0.1μF ceramic decoupling to GND |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay path | Eliminates aging drift and thermal hysteresis inherent in hybrid or LC-based delay lines |
| Equal-edge precision | Identical tPLH and tPHL tolerances ensure pulse-width preservation across all taps |
| 5-tap parallel outputs | Enables single-input, multi-delay distribution without cascading or fanout buffers |
| Industrial temperature range | Validated operation from –40°C to +85°C supports deployment in base stations and motor control enclosures |

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+ | No tape-and-reel packaging; same SO-8 footprint, electrical specs, and delay values | Suitable for hand-solder prototyping or small-batch assembly where reel feeding is unnecessary | Select DS1100LZ-250+T when automated SMT placement and traceable lot-controlled procurement are required |
| DS1100LU-250+T | Same delay values and specs, but in 8-pin µMAX (3mm × 3mm) package - 60% smaller footprint than SO-8 | Better suited for space-constrained portable instrumentation where board area is critical | Choose DS1100LU-250+T only if layout supports µMAX land pattern and reflow profile accommodates fine-pitch gull-wings |
Compared with DS1100LZ-250+, the DS1100LZ-250+T adds tape-and-reel logistics support without altering performance; versus DS1100LU-250+T, it trades compactness for SO-8 manufacturability and thermal mass-critical for high-reliability industrial timing.

FAQ
What is the operating voltage range for DS1100LZ-250+T?
The DS1100LZ-250+T operates from 3.0V to 3.6V, optimized for 3.3V logic systems. This range ensures robust noise immunity while maintaining compatibility with standard LVTTL and CMOS interfaces. Supply voltage variation within this band causes monotonic delay shifts across all taps, as documented in the datasheet's voltage tolerance note. DS1100LZ-250+T must not be operated outside these limits to guarantee specified timing accuracy or reliability.
How does DS1100LZ-250+T handle input pulse width and rise/fall time?
DS1100LZ-250+T requires a minimum input pulse width of 500ns and supports rise/fall times up to 3.0ns (10%–90%). These constraints ensure clean edge detection at the 1.5V threshold used for delay measurement. Shorter pulses may cause incomplete tap activation or inconsistent delay reporting. The DS1100LZ-250+T datasheet specifies test conditions using 50Ω source impedance and controlled edge rates-deviations require validation in the target system.
Can DS1100LZ-250+T reproduce both rising and falling edges with equal accuracy?
Yes, DS1100LZ-250+T is explicitly designed for equal leading- and trailing-edge precision. Its internal architecture guarantees matched tPLH and tPHL tolerances across all five taps, preserving pulse width integrity. This behavior is validated over –40°C to +85°C and 3.0V–3.6V supply, with ±4ns absolute tolerance for TAP1–TAP3 and ±13% for TAP4–TAP5. DS1100LZ-250+T achieves this without external calibration or feedback loops.
What is the maximum capacitive load DS1100LZ-250+T can drive per tap?
Each tap of DS1100LZ-250+T is rated to drive up to 10 LS-TTL loads, equivalent to ~20pF total capacitance with appropriate termination. Driving heavier loads increases output rise/fall times and may degrade delay accuracy due to RC-induced edge rounding. For loads exceeding this, DS1100LZ-250+T should be buffered with a 74LVC or similar low-skew driver. The datasheet confirms performance under "one 74F04 input gate" test loading.
Is DS1100LZ-250+T pin-compatible with other DS1100L variants?
Yes, all DS1100LZ-xxx and DS1100LU-xxx variants share identical pinouts within their respective packages: SO-8 for DS1100LZ-xxx and µMAX for DS1100LU-xxx. DS1100LZ-250+T uses the same SO-8 pin assignment as DS1100LZ-100+T or DS1100LZ-500+T-only the delay values differ. No PCB redesign is needed when substituting between DS1100LZ-xxx parts, provided the same package suffix (Z or U) is maintained.
