Product details
Overview
DS1100LZ-25+T from Maxim Integrated is a 3.3V, 5-tap silicon delay line delivering precise, equally spaced delays of 5ns, 10ns, 15ns, 20ns, and 25ns with ±2ns tolerance at +25°C/3.3V. It reproduces both leading and trailing edges with equal accuracy, drives up to 10 LS-TTL loads per tap, and operates across -40°C to +85°C in an 8-pin SOIC package - used for timing alignment in high-speed digital logic and clock deskew applications.
For engineers reviewing the DS1100LZ-25+T datasheet, DS1100LZ-25+T pinout, DS1100LZ-25+T application, or DS1100LZ-25+T equivalent, key selection criteria include tap delay precision over temperature/voltage, TTL/CMOS compatibility, low-power CMOS operation, and SOIC-8 surface-mount packaging for PCB area efficiency.
Technical Context
The DS1100LZ-25+T implements a monolithic all-silicon delay line architecture with five fixed-output taps, each replicating the input logic state after a deterministic delay. Delay values are factory-trimmed and specified with absolute tolerances (±2ns for ≤40ns delays) and percentage tolerances (±5% for >40ns), referenced to nominal values at +25°C and VCC = 3.3V.
It features dual-edge fidelity: tPLH and tPHL are matched within tolerance, enabling accurate pulse-width preservation. Each output supports 8mA sink / -1mA source drive under VCC = 3.0V minimum, meeting LS-TTL loading requirements without external buffers.
Key Specifications

| 6 | TAP 3 | Third delayed output, 15ns nominal delay from IN. |
| 7 | TAP 1 | First delayed output, 5ns nominal delay from IN - shortest fixed delay. |
| 8 | VCC | +3.3V supply pin - must be decoupled locally with 0.1μF ceramic capacitor. |
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 |
|---|---|---|---|
| DS1000LZ-25+T | 5V supply range (4.5V–5.5V); same 5-tap topology and SOIC-8 package. | Requires 5V rail; not suitable for 3.3V-only systems without level translation. | Select when legacy 5V logic domains dominate and voltage compatibility is confirmed. |
| MAX9992EUA+T | Programmable 8-tap delay (1–100ns in 1ns steps); µMAX-8 package; higher ICC (15mA typical). | Offers dynamic delay adjustment via serial interface; requires SPI control and additional decoupling. | Select when adaptive delay tuning or finer resolution is required - at cost of design complexity. |
Compared with DS1100LZ-25+T, DS1000LZ-25+T serves 5V systems but lacks 3.3V compatibility, while MAX9992EUA+T adds programmability and resolution at higher power and interface overhead - DS1100LZ-25+T remains optimal for fixed, low-cost, low-power 3.3V timing alignment.

FAQ
What is the nominal delay value for each tap of the DS1100LZ-25+T?
The DS1100LZ-25+T provides five equally spaced nominal delays: TAP 1 = 5ns, TAP 2 = 10ns, TAP 3 = 15ns, TAP 4 = 20ns, and TAP 5 = 25ns. These values are factory-trimmed and guaranteed over -40°C to +85°C with ±2ns tolerance for delays ≤40ns at +25°C/3.3V. The DS1100LZ-25+T datasheet Table 1 confirms this exact mapping for the "-25" suffix.
Does the DS1100LZ-25+T support both rising and falling edge delays with equal accuracy?
Yes, the DS1100LZ-25+T is explicitly designed to reproduce both leading and trailing edges with equal precision. Its tPLH (rising-edge delay) and tPHL (falling-edge delay) are matched within the same tolerance specification (±2ns for ≤40ns delays), ensuring pulse-width integrity. This dual-edge fidelity is confirmed in the General Description and AC Electrical Characteristics sections of the DS1100LZ-25+T datasheet.
What logic families can the DS1100LZ-25+T directly interface with?
The DS1100LZ-25+T features TTL-/CMOS-compatible inputs (VIH ≥ 2.0V, VIL ≤ 0.8V) and outputs capable of driving up to 10 LS-TTL loads. It operates from 3.0V to 3.6V, making it interoperable with 3.3V LVTTL, LVCMOS, and mixed 3.3V/5V systems using appropriate level-shifting only for 5V inputs. The DS1100LZ-25+T pinout and DC specs confirm direct compatibility without external buffers in standard 3.3V logic environments.
Is the DS1100LZ-25+T RoHS-compliant and suitable for lead-free reflow?
Yes, the "+T" suffix in DS1100LZ-25+T indicates a lead(Pb)-free, RoHS-compliant SOIC-8 package rated for vapor-phase and infrared reflow up to +260°C. The Package Information section specifies Pb-free compliance, and Absolute Maximum Ratings list +260°C as the peak reflow temperature - fully aligned with JEDEC J-STD-020D. DS1100LZ-25+T meets modern manufacturing environmental requirements without derating.
Can the DS1100LZ-25+T replace older DS1100 variants in existing designs?
The DS1100LZ-25+T is the 3.3V version of the original 5V DS1100 and is not a direct drop-in replacement due to different supply voltage requirements (3.0–3.6V vs. 4.5–5.5V). However, it shares identical pinout, tap count, and delay structure with the DS1100L family. Migration requires verifying VCC rail compatibility and adjusting decoupling - the DS1100LZ-25+T datasheet explicitly positions it as the 3.3V counterpart to the DS1100 series.
