Product details
Overview
DS1100LZ-125+T from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 25ns (TAP1), 50ns (TAP2), 75ns (TAP3), 100ns (TAP4), and 125ns (TAP5), operating from -40°C to +85°C in an 8-pin SOIC package. It reproduces both leading and trailing edges with ±4ns tolerance over full temperature range and drives up to 10 LS-TTL loads per tap.
For engineers reviewing the DS1100LZ-125+T datasheet, DS1100LZ-125+T pinout, DS1100LZ-125+T application, or DS1100LZ-125+T equivalent, this device serves as a precision, all-silicon timing element for edge-aligned signal conditioning, clock deskew, and pulse-width control in high-reliability digital systems where hybrid delay lines are unsuitable.
Technical Context
The DS1100LZ-125+T implements a monolithic CMOS delay chain with five fixed, equally spaced taps-each delivering deterministic propagation delay referenced to the input edge at 1.5V threshold. Delay stability is maintained across 3.0V–3.6V supply and -40°C to +85°C via process-trimmed silicon delay elements, not RC or LC networks.
It supports TTL-/CMOS-compatible logic levels (VIH ≥ 2.0V, VIL ≤ 0.8V), exhibits <2.5ns output rise/fall time, and guarantees input-to-tap delay tolerance of ±13% for delays >40ns (e.g., TAP5 = 125ns ±16.25ns) under full industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - Enables direct integration into 3.3V logic domains without level-shifting. |
| Nominal Tap Delays | TAP1=25ns, TAP2=50ns, TAP3=75ns, TAP4=100ns, TAP5=125ns - Fixed, calibrated delays for precise multi-point signal sampling. |
| Delay Tolerance | ±13% over -40°C to +85°C - Ensures predictable inter-tap skew in industrial environments. |
| Output Drive | 8mA sink / -1mA source - Sufficient to drive 10x 74LS loads without external buffering. |
| Input Pulse Width | ≥20ns (min) - Supports minimum clock/data pulse widths in high-speed digital interfaces. |
| Power-Up Time | 200μs - Allows stable operation after power rail stabilization; no external reset required. |
Pinout & Package
DS1100LZ-125+T is housed in an 8-pin SOIC (150-mil) package with standard gull-wing leads, RoHS-compliant and vapor-phase/IR solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS-compatible signals with 2.0V–3.3V high and 0V–0.8V low thresholds. |
| 2 | TAP 2 | Second delay output; delivers input signal delayed by 50ns with matched edge fidelity. |
| 3 | TAP 4 | Fourth delay output; provides 100ns delay; electrically identical to other taps in drive strength and timing accuracy. |
| 4 | GND | Digital ground reference; must be connected to system ground plane for noise immunity and timing stability. |
| 5 | TAP 5 | Fifth (longest) delay output; delivers 125ns delay; used for final-stage timing alignment or pulse extension. |
| 6 | TAP 3 | Third delay output; provides 75ns delay; enables mid-range sampling points in multi-tap sequencing. |
| 7 | TAP 1 | First delay output; delivers shortest 25ns delay; suitable for fine-grained deskew or minimal latency insertion. |
| 8 | VCC | +3.3V supply; requires local 0.1μF ceramic decoupling adjacent to pin for AC noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates aging, humidity sensitivity, and thermal hysteresis inherent in hybrid or SAW-based delay lines. |

Applications
| High-Speed Data Capture | Logic Signal Deskew |
|---|---|
Use Scenario: Capturing parallel data from high-speed ADCs or image sensors where sampling clock and data lines experience unequal PCB trace delays. IC Role / Device Role / Timing Role: DS1100LZ-125+T provides calibrated tap delays to realign data eye centers at the capture latch. Use Value: Enables reliable 100+ MSPS parallel data acquisition without FPGA-based dynamic deskew or custom PCB length matching. | Use Scenario: Aligning multiple clock domains in FPGA-to-ASIC interfaces where clock and control signals traverse different routing layers. IC Role / Device Role / Timing Role: DS1100LZ-125+T inserts precise, fixed delays on specific control lines (e.g., write-enable, chip-select) to match clock path latency. Use Value: Reduces setup/hold violations and eliminates need for manual PCB trace tuning or programmable delay ICs. |
| Pulse Width Modulation Conditioning | Digital Test Equipment Timing |
Use Scenario: Extending or trimming PWM pulses in motor driver gate control to meet MOSFET dead-time requirements. IC Role / Device Role / Timing Role: DS1100LZ-125+T generates delayed versions of PWM edges to create controlled overlap or gap windows. Use Value: Achieves sub-10ns dead-time resolution using passive, zero-power delay taps instead of active analog comparators or microcontroller-based timing. | Use Scenario: Generating synchronized trigger and strobe signals in automated test equipment (ATE) for DUT stimulus/response capture. IC Role / Device Role / Timing Role: DS1100LZ-125+T supplies multiple, phase-shifted timing references from a single input clock for sequenced test vector application. Use Value: Provides deterministic, jitter-free delay steps up to 125ns - eliminating reliance on variable-delay generators or FPGA PLL phase shifting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-100+T | Shorter max delay (100ns vs. 125ns); same 5-tap structure, SOIC-8, and electrical specs. | Suitable when longest required delay is ≤100ns; reduces design margin for 125ns-critical paths. | Select DS1100LZ-100+T only if system timing budget allows 25ns less maximum delay; otherwise retain DS1100LZ-125+T. |
| DS1100LU-125+T | Identical delay values and electrical performance, but in 8-pin µMAX (3mm × 3mm) package instead of SOIC. | Used where PCB area is constrained; requires different land pattern and reflow profile due to smaller footprint and exposed pad. | Choose DS1100LU-125+T for space-constrained designs; verify thermal relief and solder paste volume for µMAX package. |
Compared with DS1100LZ-100+T and DS1100LU-125+T, the DS1100LZ-125+T uniquely balances maximum 125ns delay capability with standard SOIC manufacturability - making it optimal for industrial control and test instrumentation where board-level reliability and assembly compatibility are prioritized over miniaturization.

FAQ
What is the operating voltage range for DS1100LZ-125+T?
The DS1100LZ-125+T operates from 3.0V to 3.6V. It is specified and tested across this full range at temperatures from -40°C to +85°C. Supply voltage directly affects delay variation: tighter VCC regulation improves delay stability, and deviations outside this window risk functional failure or parametric violation. The DS1100LZ-125+T does not support 5V or 2.5V operation.
How accurate are the tap delays of DS1100LZ-125+T over temperature?
For DS1100LZ-125+T, tap delays >40ns (including TAP5 = 125ns) have a tolerance of ±13% over -40°C to +85°C. This means TAP5 delay ranges from 108.75ns to 141.25ns. All taps track unidirectionally - if one slows, all slow - preserving inter-tap spacing. The DS1100LZ-125+T achieves this via monolithic silicon delay elements, not external components.
Can DS1100LZ-125+T drive standard TTL loads?
Yes, DS1100LZ-125+T can drive up to 10 LS-TTL loads per tap, verified per datasheet test conditions. Its output sink current is 8mA (min) and source current is -1mA (min), meeting 74LS input requirements. For heavier loads or longer traces, external buffers are recommended. The DS1100LZ-125+T maintains edge fidelity and delay accuracy only when loaded within its specified drive capability.
Is DS1100LZ-125+T pin-compatible with other DS1100L variants?
Yes, all DS1100LZ-xxx+T parts share identical 8-pin SOIC pinout and electrical interface - including DS1100LZ-125+T. Pin assignments (IN, TAP1–TAP5, VCC, GND) are fixed across the Z-suffix family. However, delay values differ per suffix (e.g., -100 vs. -125), so functional replacement requires verifying timing margins. The DS1100LZ-125+T retains full pin compatibility with DS1100LZ-25+T through DS1100LZ-500+T.
Does DS1100LZ-125+T require external decoupling capacitors?
Yes, DS1100LZ-125+T requires a 0.1μF ceramic capacitor placed as close as possible between VCC (pin 8) and GND (pin 4). This minimizes supply noise-induced jitter and ensures stable delay performance, especially during fast edge transitions. Failure to include local decoupling may cause increased delay variation or output glitches. The DS1100LZ-125+T datasheet specifies this as mandatory for guaranteed operation.
