Product details
Overview
DS1100LZ-35 from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 7ns (TAP 1) through 35ns (TAP 5), operating from −40°C to +85°C in an 8-pin SO package. It reproduces both leading and trailing edges with ±4ns tolerance over full temperature range, drives up to 10 LS-TTL loads per tap, and targets precision timing in high-speed digital synchronization circuits.
For engineers reviewing the DS1100LZ-35 datasheet, DS1100LZ-35 pinout, DS1100LZ-35 application, or DS1100LZ-35 equivalent, key selection factors include tap delay accuracy across voltage/temperature, CMOS/TTL compatibility, low-power operation (10mA typical ICC), and SO-8 surface-mount footprint suitability for space-constrained PCBs.
Technical Context
The DS1100LZ-35 implements a monolithic all-silicon delay architecture with five fixed, equally spaced delay taps referenced to a single input signal. Each tap delivers identical edge fidelity-±4ns max delay variation over −40°C to +85°C at 3.0V–3.6V supply-with no external components required.
Its logic-level interface accepts TTL-/CMOS-compatible inputs (VIH ≥ 2.0V, VIL ≤ 0.8V), outputs drive 74LS loads directly, and propagation delay stability is maintained via internal voltage/temperature compensation-not adjustable or programmable. Power-up time is 200μs; rise/fall times are 2.0–2.5ns.
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 tolerance |
| Nominal Tap Delays | TAP1=7ns, TAP2=14ns, TAP3=21ns, TAP4=28ns, TAP5=35ns - fixed, factory-trimmed delays for deterministic signal alignment |
| Delay Tolerance | ±4ns (≤40ns taps) over −40°C to +85°C - guarantees timing margin in industrial environments |
| Output Drive | 8mA sink / −1mA source - sufficient for direct interfacing with 74LS logic without buffers |
| Input Capacitance | 5–10pF - minimizes loading on preceding driver stage and preserves signal integrity |
| Power Consumption | 10mA typical ICC at 1MHz - enables low-power timing in battery-sensitive or thermally constrained designs |
Pinout & Package
DS1100LZ-35 is housed in an 8-pin SOIC (150-mil) package with standard gull-wing leads, RoHS-compliant (indicated by "+" suffix), and compatible with vapor-phase and IR reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input accepting TTL/CMOS levels; triggers all five delay taps simultaneously |
| 2 | TAP 2 | Second delay output (14ns); electrically isolated, capable of driving 10 LS loads |
| 3 | TAP 4 | Fourth delay output (28ns); matches TAP 2 in drive strength and timing spec |
| 4 | GND | Analog/digital ground reference; must be low-impedance for delay stability |
| 5 | TAP 5 | Fifth delay output (35ns); longest fixed delay in series; same edge accuracy as other taps |
| 6 | TAP 3 | Third delay output (21ns); center tap enabling symmetric delay distribution |
| 7 | TAP 1 | First delay output (7ns); shortest fixed delay; used for fine-grained skew correction |
| 8 | VCC | +3.3V supply pin; requires local 0.1μF ceramic decoupling adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay core | Eliminates hybrid or ceramic delay line reliability risks and enables 100% wafer-level testability |
| Equal-edge precision | Identical ±4ns tolerance for both rising and falling edges supports clean clock/data alignment |
| 5-tap fixed delay architecture | Provides deterministic, non-programmable delays ideal for production-critical timing paths |
| 3.3V CMOS/TTL compatibility | Direct interface with FPGA I/O banks, microcontroller GPIOs, and legacy logic families |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay timing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000LZ-35 | 5V supply only (4.75V–5.25V); same tap spacing and SO-8 package | Requires 5V rail; not suitable for mixed 3.3V/5V systems without level shifting | Select when legacy 5V logic infrastructure exists and power efficiency is secondary |
| MAX9601ASA+ | Programmable 1–100ns delay in 1ns steps; 10-bit SPI interface; 3.3V only | Introduces digital control complexity and layout sensitivity; higher BOM cost | Select when dynamic delay adjustment or multi-channel synchronization is required |
Compared with DS1100LZ-35, DS1000LZ-35 trades 3.3V compatibility for broader legacy support, while MAX9601ASA+ adds programmability at the cost of deterministic timing assurance and increased design validation effort.

FAQ
What is the maximum operating frequency supported by DS1100LZ-35?
The DS1100LZ-35 does not specify a maximum operating frequency, but its input pulse width (tWI) must be ≥20% of the TAP 5 delay (i.e., ≥7ns). For reliable operation, input periods should exceed 1μs (1MHz repetition rate), as higher frequencies increase ICC and may degrade delay accuracy due to layout sensitivity. DS1100LZ-35 remains functional beyond 1MHz, but timing margins must be verified per application.
Does DS1100LZ-35 require external decoupling capacitors?
Yes, DS1100LZ-35 requires a 0.1μF ceramic capacitor placed as close as possible between VCC (pin 8) and GND (pin 4) to suppress supply noise and maintain delay stability. This is explicitly specified in the Test Conditions section and critical for achieving ±4ns delay tolerance across temperature and voltage. DS1100LZ-35 exhibits low PSRR, making local decoupling mandatory in production designs.
Can DS1100LZ-35 be used to delay both clock and data signals simultaneously?
Yes, DS1100LZ-35 accepts a single input and replicates it across five independent, fixed-delay outputs. This allows simultaneous delay of clock and data paths-for example, routing IN to a clock domain and selecting TAP3 (21ns) for data alignment. All taps share identical edge fidelity, so DS1100LZ-35 maintains inter-signal timing relationships without added jitter or skew.
Is DS1100LZ-35 pin-compatible with other DS1100L variants like DS1100LZ-50?
Yes, all DS1100LZ-xxx variants-including DS1100LZ-35-share identical 8-pin SOIC pinout, electrical interface, and DC/AC specifications except for nominal delay values. Board designs can swap DS1100LZ-35 for DS1100LZ-50 without layout changes, provided system timing margins accommodate the 15ns longer TAP5 delay.
What is the meaning of the "Z" in DS1100LZ-35?
The "Z" in DS1100LZ-35 denotes the 8-pin SOIC (150-mil) package variant, distinguishing it from the µMAX package (U suffix, e.g., DS1100LU-35). Both packages share identical timing performance and electrical specs, but DS1100LZ-35 uses industry-standard SO footprint for ease of assembly and inspection. The "Z" carries no functional difference-it is purely a packaging identifier for DS1100LZ-35.
