Product details
Overview
DS1100LZ-45+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 9ns (TAP 1), 18ns (TAP 2), 27ns (TAP 3), 36ns (TAP 4), and 45ns (TAP 5), operating over -40°C to +85°C, driving up to 10 LS-TTL loads per tap, and housed in an 8-pin SOIC package for high-density timing control in digital signal alignment.
For engineers reviewing the DS1100LZ-45+ datasheet, DS1100LZ-45+ pinout, DS1100LZ-45+ application, or DS1100LZ-45+ equivalent, key selection considerations include tap delay precision (±4ns over full temperature range), leading/trailing edge matching, 3.3V CMOS/TTL compatibility, and SOIC-8 footprint suitability for high-speed logic synchronization and clock skew management.
Technical Context
The DS1100LZ-45+ implements a monolithic all-silicon delay architecture with five fixed, equally spaced output taps referenced to a single input signal. Each tap reproduces both rising and falling edges with matched propagation delay tolerance, enabling precise phase-aligned signal distribution without external compensation.
It operates across 3.0V–3.6V supply and supports input pulse widths down to 20% of TAP 5 delay (≥9ns), with rise/fall times ≤2.5ns and power-up time ≤200μs-optimized for deterministic timing in synchronous digital systems requiring sub-nanosecond edge fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in modern 3.3V logic domains with ±0.3V margin |
| Nominal Tap Delays | 9ns / 18ns / 27ns / 36ns / 45ns - fixed, equally spaced delays for multi-point signal staging |
| Delay Tolerance | ±4ns (≤40ns taps) or ±13% (>40ns taps) over -40°C to +85°C - guarantees predictable skew across industrial temp range |
| Output Drive | 8mA sink / -1mA source - sufficient to drive 10x 74LS loads without external buffering |
| Input-to-Output Edge Matching | Equal tPLH and tPHL precision - eliminates duty-cycle distortion in delayed clock/data paths |
| Rise/Fall Time | ≤2.5ns - preserves signal integrity for >200MHz edge rates in high-speed logic interfaces |
Pinout & Package
DS1100LZ-45+ is packaged in an 8-pin SOIC (150-mil width), surface-mount outline S8+4, RoHS-compliant and vapor-phase/IR solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input accepting TTL/CMOS-compatible signals |
| 2 | TAP 2 | Second fixed-delay output (18ns), fully buffered and LS-load capable |
| 3 | TAP 4 | Fourth fixed-delay output (36ns), electrically identical to other taps |
| 4 | GND | Digital ground reference for all I/O and internal delay circuitry |
| 5 | TAP 5 | Fifth fixed-delay output (45ns), highest-delay tap with same timing accuracy |
| 6 | TAP 3 | Third fixed-delay output (27ns), center tap for symmetric delay distribution |
| 7 | TAP 1 | First fixed-delay output (9ns), lowest-latency tap for fine-grained timing adjustment |
| 8 | VCC | +3.3V supply pin - decoupling capacitor required at pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay line | Eliminates hybrid ceramic or analog delay drift; enables 100% wafer-level testability and long-term stability |
| Leading & trailing edge accuracy | Ensures duty cycle preservation across all taps-critical for clock retiming and data eye alignment |
| Five equally spaced taps | Provides discrete, calibrated delay steps without interpolation or external components |
| 3.3V low-power CMOS | Draws only 10mA typical at 1MHz, reducing thermal load and simplifying power rail design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-50+ | 50ns maximum tap delay (vs. 45ns); same SOIC-8 package and electrical specs | Better suited for longer interconnect skew correction where 5ns extra margin is needed | Select DS1100LZ-50+ when system-level timing budget requires ≥50ns total delay headroom |
| MAX9600ASA+ | Programmable 8-tap delay (1–256ns in 1ns steps); 8-pin SOIC but higher ICC (25mA) | Supports dynamic delay adjustment via SPI-unsuitable for static, set-and-forget timing | Choose MAX9600ASA+ only if field-updatable delay resolution is required; otherwise DS1100LZ-45+ offers lower cost and power |
Compared with DS1100LZ-50+ and MAX9600ASA+, the DS1100LZ-45+ delivers optimal balance of fixed-precision delay, industrial temperature stability, and ultra-low power-making it ideal for cost-sensitive, high-volume embedded timing where tap granularity and edge fidelity outweigh programmability.

FAQ
What is the maximum operating temperature range for DS1100LZ-45+?
The DS1100LZ-45+ is rated for continuous operation from -40°C to +85°C, meeting industrial temperature requirements. This range is guaranteed across all electrical specifications-including delay tolerance, drive strength, and power consumption-as validated in the Absolute Maximum Ratings and DC/AC Electrical Characteristics tables of the official datasheet.
Does DS1100LZ-45+ support both rising and falling edge delay accuracy?
Yes, DS1100LZ-45+ is explicitly designed to reproduce both leading and trailing edges with equal precision. Its all-silicon architecture ensures matched tPLH and tPHL delays across all five taps, preserving duty cycle integrity-critical for clock retiming and data eye alignment in high-speed digital interfaces.
What load can each tap of DS1100LZ-45+ drive?
Each tap of DS1100LZ-45+ can drive up to 10 standard 74LS logic inputs, corresponding to an output sink current of 8mA and source current of -1mA under minimum VCC (3.0V). This capability is verified across the full industrial temperature range and does not require external buffers for typical TTL/CMOS interfacing.
Is DS1100LZ-45+ RoHS-compliant and lead-free?
Yes, DS1100LZ-45+ carries the "+" suffix, indicating full RoHS compliance and lead-free construction per EU Directive 2011/65/EU. It supports vapor-phase and IR reflow soldering with a peak temperature of +260°C, and its SOIC-8 package (S8+4 outline) meets JEDEC standards for lead-free assembly.
How are the tap delays calibrated in DS1100LZ-45+?
The tap delays in DS1100LZ-45+ are factory-trimmed monolithic silicon delays-no external components or calibration required. Nominal values (9ns, 18ns, 27ns, 36ns, 45ns) are guaranteed at +25°C/VCC=3.3V, with tolerances of ±4ns over -40°C to +85°C for delays ≤40ns, as specified in Table 1 and AC Electrical Characteristics.
