Product details
Overview
DS1100LZ-100+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 20ns, 40ns, 60ns, 80ns, and 100ns across TAP1–TAP5; features TTL/CMOS compatibility, ±4ns delay tolerance over -40°C to +85°C, and drives up to 10 × 74LS loads per tap; used in digital timing alignment, pulse shaping, and clock deskew in industrial control and test equipment.
For engineers reviewing the DS1100LZ-100+ datasheet, DS1100LZ-100+ pinout, DS1100LZ-100+ application, or DS1100LZ-100+ equivalent, key selection considerations include tap-specific delay accuracy, 3.3V supply compliance, SO-8 package footprint, leading/trailing edge fidelity, and industrial temperature operation without hybrid-component reliability concerns.
Technical Context
The DS1100LZ-100+ implements an all-silicon delay architecture with five fixed, equally spaced taps derived from a monolithic CMOS delay chain; each tap reproduces both rising and falling edges with matched propagation characteristics, enabling precise edge-aligned signal replication without duty-cycle distortion.
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-where all taps slow or speed together under varying conditions, preserving inter-tap spacing integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic systems and avoids level-shifting circuitry |
| Nominal Tap Delays | 20ns / 40ns / 60ns / 80ns / 100ns - enables discrete, calibrated timing offsets for multi-stage synchronization |
| Delay Tolerance (TAP1–TAP3) | ±4ns over -40°C to +85°C - guarantees sub-nanosecond edge alignment consistency in harsh environments |
| Output Drive Strength | 8mA sink / -1mA source - supports direct interfacing to 74LS loads without external buffers |
| Input Logic Compatibility | TTL- and CMOS-compatible - accepts standard 3.3V logic thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V) |
| Power-Up Time | 200μs - allows stable delay operation within microseconds after power application, suitable for fast-cycling systems |
Pinout & Package
DS1100LZ-100+ uses an 8-pin SOIC (150-mil) surface-mount package (package code S8+4), optimized for PCB area efficiency and vapor-phase/IR reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended digital input accepting TTL/CMOS logic levels; triggers identical delay paths to all five taps |
| 2 | TAP 2 | Second delay output (40ns); electrically isolated, capable of driving 10 × 74LS loads |
| 3 | TAP 4 | Fourth delay output (80ns); matches TAP2/TAP1/TAP3/TAP5 in edge fidelity and load drive |
| 4 | GND | Analog/digital ground reference; must be low-impedance to maintain delay accuracy and noise immunity |
| 5 | TAP 5 | Fifth delay output (100ns); highest-delay tap, specified with same ±4ns tolerance as TAP1–TAP3 |
| 6 | TAP 3 | Third delay output (60ns); center tap enabling symmetric delay distribution around main signal path |
| 7 | TAP 1 | First delay output (20ns); lowest-latency tap, critical for fine-grained timing adjustments |
| 8 | VCC | +3.3V supply input; requires local 0.1μF ceramic decoupling to minimize supply-induced jitter |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates hybrid-component aging and thermal hysteresis, delivering long-term delay stability without recalibration |
| Leading- and trailing-edge matching | Ensures consistent pulse width preservation across all taps-critical for clock deskew and data eye alignment |
| Five equally spaced taps | Provides deterministic, linearly scalable timing offsets ideal for tapped delay-line filter implementations and phase interpolation |
| Industrial temperature range support | Validated operation from -40°C to +85°C enables deployment in factory automation, motor drives, and outdoor instrumentation |
| RoHS-compliant lead-free package | S8+4 SO-8 footprint meets global environmental regulations while maintaining full backward compatibility with legacy assembly processes |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1023-100+ (Maxim) | 3-tap, 100ns max delay; ±5% tolerance (vs. ±4% for DS1100LZ-100+ at >40ns); SO-8 package | Limited to coarse delay steps; lacks TAP2/TAP4 for intermediate alignment points | Select when only three delay points are needed and ±5% tolerance is acceptable |
| 74FCT807CTSO (ON Semiconductor) | 8-bit programmable delay; 0–25.5ns range in 0.5ns steps; 5V-only supply; SO-20 package | Requires configuration interface and external clock; not drop-in compatible due to pin count and voltage | Select when fine-grained, adjustable delay is required and board space allows larger package |
Compared with DS1100LZ-100+, DS1023-100+ offers fewer taps and looser tolerance but shares the same SO-8 footprint and 3.3V operation, while 74FCT807CTSO provides programmability at the cost of complexity, voltage incompatibility, and layout redesign.

FAQ
What is the maximum operating frequency supported by DS1100LZ-100+?
The DS1100LZ-100+ is characterized for reliable operation up to 1MHz input frequency, with active current (ICC) specified at that rate. Higher frequencies increase ICC and may degrade delay accuracy due to layout- and decoupling-sensitive effects; the device does not specify a hard upper frequency limit but is intended for periodic or burst-mode digital timing-not continuous high-frequency clock distribution.
Does DS1100LZ-100+ require external termination or biasing resistors?
No, DS1100LZ-100+ does not require external termination or biasing resistors. Its inputs and outputs are fully CMOS/TTL compatible with defined VIH/VIL thresholds and drive strength sufficient for 10 × 74LS loads. A 0.1μF ceramic decoupling capacitor on VCC is mandatory for stable delay performance, but no pull-up, pull-down, or series termination is needed under standard loading conditions.
How does DS1100LZ-100+ handle input pulse widths shorter than the minimum specified in the datasheet?
DS1100LZ-100+ specifies a minimum input pulse width (tWI) of 20% of the TAP5 delay (i.e., 20ns for DS1100LZ-100+). Pulses narrower than this may result in incomplete propagation through the delay chain, causing missing or attenuated outputs at later taps. The device is not guaranteed to reproduce sub-20ns pulses reliably-designs requiring ultra-narrow pulses should verify behavior empirically or select a variant with shorter nominal delays.
Can DS1100LZ-100+ be used in systems with mixed 3.3V and 5V logic domains?
DS1100LZ-100+ operates strictly at 3.3V (3.0V–3.6V) and is TTL-/CMOS-compatible, meaning it accepts 5V-tolerant input levels (VIH ≥ 2.0V) but its outputs swing only to ~3.3V. Direct connection to 5V logic inputs may violate VIH requirements unless those inputs are 3.3V-tolerant; level translation is recommended for robust interfacing with true 5V CMOS or TTL receivers.
Is the delay variation between TAP1 and TAP5 affected by supply voltage changes?
Yes-delay variation across all taps scales unidirectionally with supply voltage: lower VCC increases delay, higher VCC decreases delay. However, the *relative spacing* between taps remains constant because all taps share the same delay chain structure. For DS1100LZ-100+, the ±4ns tolerance specification already accounts for combined voltage and temperature effects over 3.0V–3.6V and -40°C to +85°C, so inter-tap skew stays within datasheet limits under normal operation.
