Product details
Overview
DS1135LU-10 from Maxim Integrated is a 3V, triple-output silicon delay line IC delivering precise 10 ns propagation delays (tPLH/tPHL) on all three outputs with ±1.0 ns initial tolerance and ±3.0 ns tolerance over -40°C to +85°C. It features independent buffered delays, leading/trailing edge symmetry preservation, and operates across 2.7V–3.6V supply range. Used in high-speed timing alignment for FPGA clock deskew and digital signal synchronization.
For engineers reviewing the DS1135LU-10 datasheet, DS1135LU-10 pinout, DS1135LU-10 application, or DS1135LU-10 equivalent, this page provides verified delay accuracy, thermal/voltage stability data, SO-8 package layout, and functional alternatives for logic-level pulse timing control in industrial and embedded systems.
Technical Context
The DS1135LU-10 implements three independent CMOS-buffered delay paths in a single monolithic silicon structure-no external components required. Each path guarantees matched tPLH and tPHL within ±1.0 ns at +25°C and maintains ≤3.0 ns total variation across -40°C to +85°C and 2.7V–3.6V supply.
It uses internal precision RC timing with active edge tracking to preserve input waveform symmetry; rise/fall times are specified at 2.0–2.5 ns into 15 pF load. Power-up time is 1 ms, and it supports reflow soldering per JEDEC J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 10 ns ±1.0 ns (initial), ±3.0 ns (full temp/volt range) |
| Supply voltage | 2.7V–3.6V - enables direct interface with 3.3V logic families without level shifting |
| Output rise/fall time | 2.0–2.5 ns - ensures clean transitions into 15 pF loads typical of 74F04-equivalent inputs |
| Operating temperature | -40°C to +85°C - qualified for industrial-grade embedded timing applications |
| Active current | 10 mA max at 3.6V/1 µs period - low power for high-density timing subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-output delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1033Z-10+ | 5V-only operation (4.5–5.5V); ±2.5 ns temp/volt tolerance over -40°C to +85°C | Requires level translation when interfacing with 3.3V systems; higher power consumption | Select only if legacy 5V infrastructure mandates compatibility |
| MAX9601EUA+ | Single-output, 10 ns delay; 2.7–5.5V supply; ±0.5 ns initial tolerance | Lacks multi-output capability; requires three devices for equivalent functionality | Choose when board space allows discrete delay paths and tighter initial accuracy is prioritized |
Compared with DS1135LU-10, DS1033Z-10+ offers broader voltage tolerance but lacks 3V compatibility, while MAX9601EUA+ gives superior initial accuracy yet triples component count and layout complexity for three-path alignment.

FAQ
What is the guaranteed delay accuracy of DS1135LU-10 over temperature and voltage?
The DS1135LU-10 guarantees ±3.0 ns total delay variation across -40°C to +85°C and 2.7V–3.6V supply. This includes both initial tolerance (±1.0 ns at +25°C/3.3V) and additional drift due to temperature and voltage changes. Measured at 1.5V crossing points for both rising and falling edges, ensuring symmetrical timing behavior essential for clock and data alignment tasks using DS1135LU-10.
Does DS1135LU-10 support reflow soldering, and what are the profile limits?
Yes, DS1135LU-10 is qualified for vapor-phase and infrared reflow soldering per JEDEC J-STD-020. Peak reflow temperature must not exceed +260°C for ≤10 seconds, and lead temperature is rated to +300°C for 10 seconds. The device's SO-8 (150-mil) package is fully compatible with standard surface-mount assembly processes used for DS1135LU-10 deployment in industrial PCBs.
Can DS1135LU-10 replace DS1033Z-10+ directly in a 3.3V system?
No - DS1033Z-10+ is a 5V-only device (4.5–5.5V), making it incompatible with 3.3V logic without level-shifting circuitry. DS1135LU-10 was explicitly designed as the recommended 3V replacement for DS1033, offering identical 10 ns delay but with full 2.7–3.6V operation, lower power, and improved thermal stability. Direct substitution of DS1135LU-10 avoids redesign in new 3V systems.
How does DS1135LU-10 preserve input signal symmetry between leading and trailing edges?
DS1135LU-10 employs matched internal delay paths and active edge-tracking circuitry to ensure tPLH and tPHL remain equal within ±1.0 ns initially and ±3.0 ns over full operating conditions. This preserves input duty cycle and prevents pulse-width distortion - critical when aligning clock or data signals where skew between rising/falling edges degrades timing margins. The design achieves this without external compensation, unlike RC-based delay solutions.
What is the maximum capacitive load DS1135LU-10 can drive while maintaining specified rise/fall times?
DS1135LU-10 is characterized to drive a 15 pF load - equivalent to one 74F04 input gate - while maintaining 2.0–2.5 ns rise/fall times. Driving heavier loads will increase transition times and may affect delay accuracy due to output stage slew-rate limitations. For loads >15 pF, buffer amplification or layout optimization is recommended to retain DS1135LU-10's specified timing performance.
