Product details
Overview
DS1100LZ-40+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 8ns (TAP 1), 16ns (TAP 2), 24ns (TAP 3), 32ns (TAP 4), and 40ns (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 LS-TTL loads per tap, used in high-speed timing alignment and signal skew correction.
For engineers reviewing the DS1100LZ-40+ datasheet, DS1100LZ-40+ pinout, DS1100LZ-40+ application, or DS1100LZ-40+ equivalent, key selection criteria include tap delay accuracy over temperature/voltage, edge fidelity, output drive strength, and SO-8 compatibility for PCB-constrained digital systems.
Technical Context
The DS1100LZ-40+ implements a monolithic all-silicon delay architecture with five fixed, equally spaced delay taps referenced to a single input. Each tap delivers deterministic propagation delay with ±4ns tolerance over -40°C to +85°C at 3.3V, maintaining consistent relative spacing across voltage and temperature.
It operates as a passive, non-retriggerable delay element: input logic state is replicated at each tap after its specified delay, with no internal clocking, feedback, or programmability. Rise/fall times are ≤2.5ns, and power-up time is 200μs - enabling use in static timing paths without synchronization overhead.
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. |
| Nominal Tap Delays | TAP1=8ns, TAP2=16ns, TAP3=24ns, TAP4=32ns, TAP5=40ns - enables precise, multi-point timing alignment in serial data paths or clock distribution networks. |
| Delay Tolerance | ±4ns (≤40ns delays) over -40°C to +85°C - guarantees predictable skew control without calibration. |
| Output Drive | 8mA sink / -1mA source - supports direct interfacing to 74LS/74F logic without external buffers. |
| Input/Output Edge Accuracy | Equal leading- and trailing-edge delay matching - preserves pulse width integrity for duty-cycle-sensitive applications. |
| Power-Up Time | 200μs - defines minimum reset-to-valid-output interval after supply stabilization. |
Pinout & Package
DS1100LZ-40+ is housed in an 8-pin SOIC (150-mil) surface-mount package, RoHS-compliant and lead(Pb)-free, with standard JEDEC MS-012AC footprint and vapor-phase/IR solder compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended TTL/CMOS-compatible input; accepts 0–3.3V logic levels with ≤10pF input capacitance. |
| 2 | TAP 2 | Second delay tap output; delivers input signal delayed by 16ns with matched rise/fall characteristics. |
| 3 | TAP 4 | Fourth delay tap output; delivers input signal delayed by 32ns, usable for intermediate timing sampling or phase interpolation. |
| 4 | GND | Digital ground reference; must be connected to system ground plane for noise immunity and delay stability. |
| 5 | TAP 5 | Fifth delay tap output; delivers full 40ns delay, commonly used for maximum skew compensation or echo cancellation timing. |
| 6 | TAP 3 | Third delay tap output; provides 24ns delay, positioned mid-range for balanced interpolation between TAP2 and TAP4. |
| 7 | TAP 1 | First delay tap output; delivers shortest 8ns delay, suitable for fine-grained timing adjustment or setup-time margining. |
| 8 | VCC | +3.3V supply; requires local 0.1μF ceramic decoupling adjacent to pin for AC noise suppression and delay consistency. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates hybrid or ceramic delay line reliability risks and enables wafer-level testing and guaranteed lifetime performance. |
| Five equally spaced taps | Provides deterministic, linearly scalable delay points - simplifies timing margin analysis and eliminates need for multiple discrete delay elements. |
| Leading- and trailing-edge accuracy | Maintains input pulse width within ±0.5ns deviation - critical for high-fidelity signal replication in test equipment and data capture systems. |
| TTL-/CMOS-compatible I/O | Direct interface with legacy 74LS and modern 3.3V logic families without level-shifting circuitry or external biasing. |
Applications
| High-Speed Logic Timing Alignment | Signal Skew Compensation |
|---|---|
Use Scenario: Aligning clock and data signals in parallel bus interfaces where trace length mismatches cause setup/hold violations. IC Role / Device Role / Timing Role: Static delay element providing calibrated, fixed offsets to match propagation delays across signal lanes. Use Value: Enables reliable 100MHz+ parallel data transfers without FPGA-based dynamic deskew or complex PCB routing. | Use Scenario: Correcting inter-channel skew in multi-lane ADC/DAC evaluation boards or high-resolution oscilloscope front-ends.

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-50+ | Delivers 10ns/20ns/30ns/40ns/50ns taps - 10ns longer final delay than DS1100LZ-40+; same SO-8 package and electrical specs. | Suitable when full 50ns skew correction or longer timing margin is required, e.g., in longer PCB traces or slower logic families. | Select DS1100LZ-50+ only if TAP5 ≥50ns is mandatory; otherwise DS1100LZ-40+ offers tighter delay resolution for sub-40ns alignment tasks. |
| DS1100LU-40+ | Identical delay values and electrical specs, but in 8-pin µMAX (U8+1) package - 3mm × 3mm vs SO-8's 4.9mm × 6.0mm footprint. | Preferred for space-constrained designs such as portable instrumentation or dense FPGA carrier boards where board area is premium. | Choose DS1100LU-40+ when PCB real estate is limited and reflow profile supports µMAX; otherwise DS1100LZ-40+ offers broader assembly compatibility. |
Compared with DS1100LZ-50+ and DS1100LU-40+, the DS1100LZ-40+ provides optimal balance of delay granularity (8ns step), SO-8 manufacturability, and thermal/power performance for mainstream industrial timing alignment - making it the default choice unless extended delay range or miniaturization is required.

FAQ
What is the operating temperature range for DS1100LZ-40+?
The DS1100LZ-40+ is fully specified and tested over -40°C to +85°C. All delay tolerances, drive capability, and DC parameters are guaranteed across this industrial temperature range, with no derating required. This makes DS1100LZ-40+ suitable for deployment in outdoor infrastructure, factory automation, and automotive under-hood environments where ambient extremes are expected.
Does DS1100LZ-40+ require external configuration or programming?
No, DS1100LZ-40+ is a fully static, unprogrammable delay line. It requires only VCC, GND, and an input signal - no clocks, control pins, or configuration registers. Once powered, DS1100LZ-40+ immediately delivers deterministic delays at all five taps with no initialization sequence or firmware dependency.
Can DS1100LZ-40+ drive 74ACT or 74HC logic directly?
Yes, DS1100LZ-40+ can drive 74ACT and 74HC families directly. Its 8mA sink / -1mA source output capability exceeds the input current requirements of these CMOS families (typically ±1μA), and its 3.3V-compatible voltage levels align with their VIH/VIL thresholds. No series termination or level-shifting is needed for point-to-point connections.
How does DS1100LZ-40+ handle input pulse widths shorter than 500ns?
DS1100LZ-40+ maintains accurate delay performance down to input pulse widths of 20% of TAP5 delay (i.e., ≥8ns). However, for pulses narrower than 500ns, delay tolerance may widen slightly due to edge-rate sensitivity; the datasheet specifies tWI ≥20% of TAP5 delay for guaranteed spec compliance. For <100ns pulses, layout decoupling and source impedance control become critical.
Is DS1100LZ-40+ pin-compatible with other DS1100L variants?
Yes, all DS1100LZ-xxx+ and DS1100LU-xxx+ variants share identical pinouts and electrical interfaces - only the nominal delay values differ. A DS1100LZ-40+ can be substituted with DS1100LZ-30+ or DS1100LZ-50+ on the same SO-8 footprint without PCB modification, provided the new delay values meet system timing requirements.
