Product details
Overview
DS1100LZ-500+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 100ns, 200ns, 300ns, 400ns, and 500ns across TAP 1–TAP 5. It operates from 3.0V to 3.6V over –40°C to +85°C, reproduces both leading and trailing edges with equal precision, and drives up to 10 74LS loads per tap. Used in high-speed timing alignment for test equipment and digital signal synchronization.
For engineers reviewing the DS1100LZ-500+ datasheet, DS1100LZ-500+ pinout, DS1100LZ-500+ application, or DS1100LZ-500+ equivalent, key selection criteria include tap delay accuracy (±13% over full temperature range), SO-8 package compatibility, TTL/CMOS logic interface, and 2.5ns max output rise/fall time - critical for jitter-sensitive clock distribution and pulse-shaping circuits.
Technical Context
The DS1100LZ-500+ implements an all-silicon delay architecture with five fixed, equally spaced delay taps derived from a monolithic CMOS timing circuit. Each tap delivers deterministic propagation delay referenced to the 1.5V logic threshold, with matched leading/trailing edge behavior confirmed across voltage (3.0V–3.6V) and temperature (–40°C to +85°C).
Delay tolerance scales with nominal value: ±13% for delays >40ns (e.g., TAP 5 at 500ns), while input pulse width must be ≥500ns (per test conditions for -500 version). Output drive strength is specified at 8mA sink / –1mA source under VCC = 3.0V, supporting direct interfacing to legacy 74LS logic without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation with standard 3.3V LDOs and compatibility with mixed-voltage digital systems. |
| Nominal Tap Delays | 100ns / 200ns / 300ns / 400ns / 500ns - enables precise multi-stage timing alignment in serial data recovery and strobe generation. |
| Delay Tolerance | ±13% over –40°C to +85°C - defines worst-case skew budget between taps in industrial environments. |
| Output Drive | 8mA sink / –1mA source - directly interfaces with 74LS inputs without external buffers, reducing BOM count. |
| Rise/Fall Time | 2.5ns max - preserves signal integrity for >200MHz edge rates in high-speed digital test fixtures. |
| Operating Temp | –40°C to +85°C - qualified for use in automotive infotainment timing modules and industrial PLC I/O timing circuits. |
Pinout & Package
DS1100LZ-500+ is housed in an 8-pin SO (Small Outline, 150-mil width) RoHS-compliant package with gull-wing leads, compatible with standard vapor-phase and IR reflow soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Input Signal | Accepts TTL/CMOS-compatible logic pulses; 50Ω source impedance recommended for clean edge fidelity. |
| 2 TAP 2 | Second Delay Output | Delivers input signal delayed by 200ns; capable of driving 10× 74LS loads simultaneously. |
| 3 TAP 4 | Fourth Delay Output | Delivers input signal delayed by 400ns; matches TAP 2 and TAP 5 delay spacing for linear interpolation. |
| 4 GND | Ground Reference | Provides return path for all internal logic and output drivers; requires low-inductance PCB connection. |
| 5 TAP 5 | Fifth Delay Output | Delivers input signal delayed by 500ns; highest-delay tap used for maximum timing offset in calibration sequences. |
| 6 TAP 3 | Third Delay Output | Delivers input signal delayed by 300ns; center tap enabling symmetric delay windows around main event. |
| 7 TAP 1 | First Delay Output | Delivers input signal delayed by 100ns; shortest delay for fine-grained timing adjustment in setup/hold margining. |
| 8 VCC | Power Supply | +3.3V supply input; requires local 0.1µF ceramic decoupling capacitor placed within 5mm of pin. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1023-500+ (Maxim) | 3-tap device with delays at 167ns, 333ns, 500ns; higher delay tolerance (±20%) and lower drive (4 LS loads). | Suitable only where fewer taps and looser timing margins are acceptable, e.g., basic pulse stretching. | Select DS1100LZ-500+ when 5-tap resolution and 10-LS load drive are required for multi-point timing alignment. |
| MC100EP195FA (onsemi) | Differential ECL output; 5-tap, but requires –3.3V supply and level translation for single-ended systems. | Used in RF and microwave timing where differential signaling reduces noise coupling, not for cost-sensitive 3.3V logic systems. | Choose DS1100LZ-500+ for single-ended, 3.3V, low-power applications where ECL complexity and negative supplies are prohibitive. |
Compared with DS1023-500+ and MC100EP195FA, DS1100LZ-500+ uniquely balances 5-tap granularity, 3.3V CMOS compatibility, and industrial temperature support - making it optimal for embedded timing alignment where layout simplicity and supply rail constraints dominate.

FAQ
What is the maximum operating frequency supported by DS1100LZ-500+?
The DS1100LZ-500+ does not specify a maximum operating frequency, but its AC characteristics are tested with a 1μs period (1MHz) input signal. At higher frequencies, active current (ICC) increases and delay accuracy degrades due to layout sensitivity and decoupling limitations. For reliable operation, keep input pulse repetition below 5MHz and ensure tight power-supply decoupling near the DS1100LZ-500+ VCC pin.
Does DS1100LZ-500+ support both rising and falling edge delay matching?
Yes, DS1100LZ-500+ is explicitly designed to reproduce both leading and trailing edges with equal precision. Its datasheet confirms matched tPLH and tPHL delay tolerances across all five taps, verified at +25°C, 0°C to +70°C, and –40°C to +85°C. This ensures consistent pulse width preservation - critical for applications like clock retiming and strobe generation where duty cycle integrity matters.
Can DS1100LZ-500+ drive modern CMOS logic families such as 74LVC?
Yes, DS1100LZ-500+ is TTL-/CMOS-compatible and can directly drive 74LVC inputs. Its output voltage levels (VOH ≥ 2.3V at VCC = 3.0V, VOL ≤ 0.5V) and drive strength (8mA sink, –1mA source) exceed 74LVC thresholds. No level-shifting circuitry is needed, though proper PCB layout and local decoupling remain essential to maintain 2.5ns rise/fall times.
What is the meaning of the "+" suffix in DS1100LZ-500+?
The "+" suffix in DS1100LZ-500+ indicates a lead(Pb)-free and RoHS-compliant SO-8 package, per Maxim Integrated's ordering nomenclature. It uses matte tin plating and conforms to JEDEC J-STD-020 moisture sensitivity level 1. The "+" does not denote performance enhancement or extended temperature grade - DS1100LZ-500+ retains the same –40°C to +85°C operating range as non-"+" variants.
How is delay tolerance specified for DS1100LZ-500+ at full temperature range?
For DS1100LZ-500+, delay tolerance is ±13% of nominal delay (e.g., ±65ns on the 500ns TAP 5) over –40°C to +85°C. This applies to all taps since delays >40ns follow percentage-based tolerance. The specification accounts for unidirectional variation - if one tap slows, all slow proportionally - simplifying system-level skew analysis without needing per-tap worst-case combinations.
