Product details
Overview
DS1100LZ-500+T from Maxim Integrated is a 3.3V, 5-tap silicon delay line delivering precisely spaced delays of 100ns, 200ns, 300ns, 400ns, and 500ns across its output taps. It operates from 3.0V to 3.6V over -40°C to +85°C, reproduces both leading and trailing edges with ±4ns tolerance at full temperature range, and drives up to 10 LS-TTL loads per tap. It is used in high-speed digital timing alignment, clock skew correction, and pulse-width adjustment circuits.
For engineers reviewing the DS1100LZ-500+T datasheet, DS1100LZ-500+T pinout, DS1100LZ-500+T application, or DS1100LZ-500+T equivalent, key selection considerations include guaranteed 500ns maximum tap delay with ±13% tolerance over temperature/voltage, SO-8 package compatibility, 3.3V CMOS/TTL interface levels, and industrial-grade reliability without hybrid construction.
Technical Context
The DS1100LZ-500+T implements an all-silicon delay architecture with five fixed, equally spaced delay stages-no PLL, no oscillator, no programmability. Each tap replicates the input logic state after its nominal delay, with edge fidelity maintained for both rising (tPLH) and falling (tPHL) transitions at the 1.5V threshold.
Delay accuracy is specified as ±13% for TAP 5 (500ns) over -40°C to +85°C and 3.0V–3.6V supply, with unidirectional drift: all taps slow or speed together under voltage/temperature change. Input pulse width must be ≥500ns (1μs for -500 version), and power-up time is 200μs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in 3.3V systems with ±10% rail variation |
| TAP 5 Delay | 500ns nominal - provides longest fixed delay stage for timing margining or pulse stretching |
| Delay Tolerance | ±13% over -40°C to +85°C - defines worst-case timing window for synchronous alignment |
| Output Drive | 8mA sink / -1mA source - supports direct interfacing to 74LS logic without buffering |
| Input Pulse Width | 1μs minimum - sets minimum usable signal period for reliable tap activation |
| Power-Up Time | 200μs - determines minimum reset-to-valid-output latency after VCC stabilization |
| Rise/Fall Time | 2.0ns to 2.5ns - enables use in sub-500MHz digital timing paths with low jitter contribution |
Pinout & Package
DS1100LZ-500+T is housed in an 8-pin SOIC (150-mil) surface-mount package, RoHS-compliant and vapor-phase/IR solderable. Pin 1 is IN; pins 2–5 are TAP 2 through TAP 5; pin 6 is TAP 3; pin 7 is TAP 1; pin 8 is VCC; pin 4 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Signal Input | Accepts TTL/CMOS-compatible 3.3V logic; triggers all five delay paths simultaneously |
| TAP 2 (Pin 2) | Delay Output | Delivers input signal delayed by 200ns; electrically identical to other taps |
| TAP 4 (Pin 3) | Delay Output | Delivers input signal delayed by 400ns; rated for 10 LS-TTL loads |
| GND (Pin 4) | Ground Reference | Common return for VCC and all I/O; requires low-inductance PCB connection |
| TAP 5 (Pin 5) | Delay Output | Delivers input signal delayed by 500ns - longest fixed delay stage |
| TAP 3 (Pin 6) | Delay Output | Delivers input signal delayed by 300ns; shares same delay tolerance profile as TAP 5 |
| TAP 1 (Pin 7) | Delay Output | Delivers input signal delayed by 100ns; first active tap in sequence |
| VCC (Pin 8) | Power Supply | +3.3V supply input; requires local 0.1μF ceramic decoupling adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay path | Eliminates hybrid component failure modes and enables full reflow compatibility |
| Five equally spaced taps | Provides deterministic, non-overlapping delay intervals for multi-stage timing control |
| Leading- and trailing-edge accuracy | Ensures symmetrical delay for both edges - critical for pulse-width preservation |
| TTL-/CMOS-compatible I/O | Interfaces directly with legacy 74LS and modern 3.3V logic families without level shifters |
| Industrial temperature range | Validated operation from -40°C to +85°C supports deployment in harsh environments |
Applications
| Digital Clock Skew Correction | Pulse Width Adjustment |
|---|---|
Use Scenario: Aligning clock edges across multiple ASIC/FPGA domains on a single PCB to meet setup/hold timing. IC Role / Device Role / Timing Role: Fixed-delay buffer inserting precise 200ns–500ns offsets to compensate for trace-length mismatches. Use Value: Enables deterministic skew reduction without PLL complexity or phase ambiguity. | Use Scenario: Extending narrow trigger pulses from sensors or comparators to meet minimum width requirements of downstream logic. IC Role / Device Role / Timing Role: Tap 5 (500ns) output used as stretched enable signal; IN-to-TAP5 path provides exact, repeatable extension. Use Value: Guarantees 500ns minimum pulse width independent of input jitter or duty cycle variation. |
| High-Speed Data Valid Windowing | Logic Signal Retiming |
Use Scenario: Creating synchronized strobe windows for sampling parallel data buses in test equipment or protocol analyzers. IC Role / Device Role / Timing Role: TAP 1 (100ns) and TAP 3 (300ns) generate start/end boundaries of a 200ns valid window aligned to data arrival. Use Value: Provides sub-nanosecond edge repeatability essential for <500MHz bus capture integrity. | Use Scenario: Realigning asynchronous control signals (e.g., reset, interrupt) across clock domains in mixed-signal SoC interfaces. IC Role / Device Role / Timing Role: DS1100LZ-500+T acts as a deterministic retimer - IN accepts async signal, TAP 2 delivers it delayed by 200ns for metastability mitigation. Use Value: Avoids FIFO or synchronizer logic while guaranteeing known, bounded latency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1023-500+T | 5V-only supply (4.5V–5.5V); same 5-tap SO-8 layout but different delay tolerances (±10% @ 25°C only) | Not suitable for 3.3V systems; requires level translation if interfacing with LVCMOS logic | Select when legacy 5V infrastructure exists and tighter room-temp accuracy is prioritized over temperature range |
| MAX5033AESA+ | Single-output, adjustable delay (10ns–1000ns via resistor); 3.3V compatible but only one tap | Lacks multi-tap capability; requires external resistor and calibration for each delay setting | Choose when variable delay is needed and board space allows tuning components |
Compared with DS1100LZ-500+T, DS1023-500+T offers better room-temperature precision but lacks industrial temperature support and 3.3V compatibility, while MAX5033AESA+ trades fixed multi-tap simplicity for programmability at the cost of design overhead and reduced channel count.

FAQ
What is the nominal delay value for TAP 5 of the DS1100LZ-500+T?
The DS1100LZ-500+T has a nominal delay of 500ns at TAP 5, as indicated by the "-500" suffix in the part number. This value is confirmed in Table 1 of the datasheet and applies under standard test conditions (VCC = 3.3V, TA = +25°C). The actual delay varies within ±13% over the full industrial temperature and voltage range.
Does the DS1100LZ-500+T support both rising and falling edge delay accuracy?
Yes, the DS1100LZ-500+T is explicitly designed to reproduce both leading and trailing edges with equal precision. The datasheet specifies matched tPLH and tPHL tolerances across all taps, ensuring symmetrical delay behavior critical for pulse-width preservation and clock alignment tasks involving DS1100LZ-500+T.
What is the maximum output load drive capability per tap of the DS1100LZ-500+T?
Each tap of the DS1100LZ-500+T can drive up to 10 LS-TTL loads, corresponding to 8mA sink current (IOL) and -1mA source current (IOH) under minimum VCC conditions. This rating is verified in the DC Electrical Characteristics table and enables direct interfacing with legacy logic families without external buffers when using DS1100LZ-500+T.
Is the DS1100LZ-500+T RoHS-compliant and lead(Pb)-free?
Yes, the "+T" suffix in DS1100LZ-500+T indicates a lead(Pb)-free, RoHS-compliant SO-8 package. The datasheet confirms that "+" denotes RoHS compliance, and the soldering profile specifies +260°C reflow temperature for lead-free processes - fully consistent with DS1100LZ-500+T's environmental compliance documentation.
Can the DS1100LZ-500+T operate outside the 3.3V supply range?
No, the DS1100LZ-500+T is characterized and guaranteed only for operation between 3.0V and 3.6V. Operation below 3.0V may cause timing violations or output invalidity; above 3.6V risks exceeding absolute maximum ratings. The datasheet states this range explicitly in the General Description and DC Electrical Characteristics sections for DS1100LZ-500+T.
