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; operates from −40°C to +85°C; drives up to 10 × 74LS loads per tap; features equal leading/trailing-edge precision and TTL/CMOS compatibility for timing alignment in high-speed digital systems.
For engineers reviewing the DS1100LZ-100 datasheet, DS1100LZ-100 pinout, DS1100LZ-100 application, or DS1100LZ-100 equivalent, key selection factors include tap delay accuracy (±4ns over full temperature range), 3.3V supply tolerance (3.0V–3.6V), output drive capability, SO-8 package footprint, and industrial-grade thermal stability.
Technical Context
The DS1100LZ-100 implements a monolithic all-silicon delay architecture with five fixed, equally spaced delay taps derived from a single input signal. Each tap reproduces both rising and falling edges at precisely defined intervals without interpolation or programmability.
Delay values are factory-trimmed and specified with ±4ns absolute tolerance over −40°C to +85°C for delays ≤40ns (e.g., TAP1 = 20ns), and ±13% relative tolerance for longer delays (e.g., TAP5 = 100ns). Input-to-output propagation is measured at the 1.5V logic threshold under 50Ω source impedance and 3ns max input rise/fall time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation across industrial 3.3V rail tolerances without external regulation |
| Nominal Tap Delays | TAP1=20ns, TAP2=40ns, TAP3=60ns, TAP4=80ns, TAP5=100ns - enables precise multi-point timing alignment in clock/data recovery paths |
| Delay Tolerance (≤40ns) | ±4ns over −40°C to +85°C - guarantees deterministic skew control in synchronous logic interfaces |
| Output Drive Strength | 8mA sink / −1mA source at VCC min - supports direct connection to 74LS inputs without buffering |
| Input Capacitance | 5–10pF - minimizes loading on upstream drivers and preserves signal integrity in high-frequency routing |
| Power-Up Time | 200μs - allows immediate use after power stabilization; no initialization sequence required |
Pinout & Package
DS1100LZ-100 is housed in an 8-pin SO (Small Outline) package, 150-mil body width, RoHS-compliant (indicated by "+" suffix), with standard JEDEC SOIC-8 land pattern (outline 21-0041, footprint 90-0096).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended CMOS/TTL-compatible input; accepts 0V–3.3V logic with 5–10pF load |
| 2 | TAP 2 | Second delay output (40ns); delivers full-swing 3.3V logic with 8mA sink capability |
| 3 | TAP 4 | Fourth delay output (80ns); electrically identical to TAP2 but with longer propagation |
| 4 | GND | Digital ground reference; must be low-impedance and decoupled near VCC pin |
| 5 | TAP 5 | Fifth delay output (100ns); highest-delay tap; same drive strength and edge fidelity as other taps |
| 6 | TAP 3 | Third delay output (60ns); center tap used for mid-interval sampling or feedback timing |
| 7 | TAP 1 | First delay output (20ns); lowest-latency tap for minimal-skew path insertion |
| 8 | VCC | +3.3V supply; requires local 0.1μF ceramic decoupling capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay line | Eliminates hybrid or ceramic delay modules; improves long-term reliability and thermal stability vs. analog alternatives |
| Equal leading/trailing-edge accuracy | Enables precise pulse-width preservation across all taps-critical for clock forwarding and strobe generation |
| Five fixed, equally spaced taps | Provides deterministic delay steps without configuration overhead-ideal for static timing calibration |
| TTL-/CMOS-compatible I/O | Interoperates directly with legacy 74LS and modern 3.3V logic families without level-shifting circuitry |
| Vapor-phase and IR solderable | Supports standard reflow profiles including Pb-free (260°C) and SnPb (240°C) processes without package damage |
Applications
| High-Speed Logic Timing Calibration | Serial Data Eye Alignment |
|---|---|
Use Scenario: Aligning setup/hold windows between FPGA I/O banks and external memory controllers using adjustable tap outputs. IC Role / Device Role / Timing Role: Fixed-delay reference generator providing calibrated skew offsets for parallel data capture clocks. Use Value: Enables sub-nanosecond timing margin optimization without FPGA PLL tuning or PCB trace length matching. | Use Scenario: Adjusting sampling point within serial data eye for LVDS or RSDS receivers operating above 100MHz. IC Role / Device Role / Timing Role: Delay element injecting controlled phase shift into receiver clock path to maximize data valid window. Use Value: Improves bit error rate by aligning sampling edge to center of eye without requiring programmable delay ICs or FPGA-based delay chains. |
| Test Equipment Signal Strobing | Digital Oscilloscope Trigger Delay |
Use Scenario: Generating synchronized strobes for boundary-scan test vectors or JTAG state machine timing validation. IC Role / Device Role / Timing Role: Deterministic delay node converting system clock into multiple phase-shifted strobe signals. Use Value: Eliminates jitter-prone RC networks; provides repeatable, temperature-stable strobe timing across production units. | Use Scenario: Introducing precise pre-trigger delay in benchtop oscilloscope auxiliary trigger paths to capture transient events. IC Role / Device Role / Timing Role: Fixed-delay buffer placed between main trigger source and scope's external trigger input. Use Value: Allows consistent post-trigger acquisition window positioning independent of scope firmware or internal delay resolution limits. |
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 | 5V-only operation (4.75V–5.25V); ±5% delay tolerance over temp; SO-8 package | Requires level translation when interfacing with 3.3V systems; less precise at low delays | Select when legacy 5V infrastructure dominates and ±5% delay variation is acceptable |
| MAX5033AESA+ | Programmable 8-tap delay (1–256ns steps); SPI-configurable; 8-SO package; 3.3V only | Offers dynamic adjustment but adds MCU dependency and layout complexity for SPI routing | Select when variable delay or field calibration is required, not fixed-tap timing |
Compared with DS1100LZ-100, DS1023-100 trades voltage compatibility for broader legacy support, while MAX5033AESA+ replaces fixed delay with programmability at the cost of added control overhead and reduced deterministic timing assurance.

FAQ
What is the operating temperature range for DS1100LZ-100?
The DS1100LZ-100 is rated for continuous operation from −40°C to +85°C. This industrial temperature range is guaranteed across all electrical specifications, including delay tolerance (±4ns for TAP1–TAP2), supply current (10mA typical), and output drive capability. The device undergoes full characterization at temperature extremes during production test.
Does DS1100LZ-100 require external configuration or programming?
No, DS1100LZ-100 is a fully static, unprogrammable delay line. All five tap delays (20ns, 40ns, 60ns, 80ns, 100ns) are factory-trimmed and fixed. It requires only VCC, GND, and an input signal-no clocks, control lines, or configuration registers. This eliminates firmware dependencies and ensures deterministic timing behavior from power-up.
Can DS1100LZ-100 drive 74ACT or 74HC logic families directly?
Yes, DS1100LZ-100 can drive 74HC and 74ACT inputs directly. Its output drive strength (8mA sink, −1mA source) exceeds the input current requirements of both families. However, for 74ACT, verify that the 3.3V output swing meets VIH/VIL thresholds of the target device-most 74ACT variants accept 2.0V VIH minimum, which DS1100LZ-100 satisfies at VCC = 3.0V.
How does delay tolerance scale across taps for DS1100LZ-100?
For DS1100LZ-100, delay tolerance is ±4ns for TAP1 (20ns) and TAP2 (40ns), as both are ≤40ns. For TAP3 (60ns), TAP4 (80ns), and TAP5 (100ns), tolerance is ±13% of nominal value (±7.8ns, ±10.4ns, ±13ns respectively) over −40°C to +85°C. All taps track unidirectionally with temperature/voltage changes.
Is DS1100LZ-100 pin-compatible with other DS1100L variants in SO-8 package?
Yes, all DS1100LZ-xxx variants (e.g., DS1100LZ-50, DS1100LZ-200) share identical SO-8 pinout, electrical interface, and DC/AC characteristics except nominal delay values. Board designs can be reused across delay variants without layout changes-only the part number and BOM entry require update.
