Product details
Overview
DS1135LZ-25 from Maxim Integrated is a 3V, 3-in-1 high-speed silicon delay line providing three independent buffered delays of precisely 25 ns each (tPLH/tPHL), with ±1.5 ns initial tolerance and ±5.0 ns total variation over -40°C to +85°C and 2.7V–3.6V supply. It preserves input signal symmetry via leading/trailing edge precision and is used in high-speed digital timing alignment, clock deskewing, and pulse width adjustment circuits.
For engineers reviewing the DS1135LZ-25 datasheet, DS1135LZ-25 pinout, DS1135LZ-25 application, or DS1135LZ-25 equivalent, this page delivers verified timing parameters, SO-8 package mapping, industrial-temperature operation details, and direct functional alternatives for logic-level delay line replacement in embedded control and test instrumentation.
Technical Context
The DS1135LZ-25 implements all-silicon delay circuitry without external components, delivering deterministic 25 ns propagation delay on all three outputs with matched tPLH and tPHL. Its design ensures sub-nanosecond edge alignment fidelity across temperature and voltage, enabling precise pulse shaping in synchronous digital systems.
It operates exclusively from a single 3V supply (2.7V–3.6V), draws ≤10 mA active current, and supports 100% of delay value as minimum input pulse width - confirming suitability for ≥25 ns period signals. Output rise/fall times are specified at 2.0–2.5 ns into 15 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 25 ns (tPLH/tPHL), matched across all three channels |
| Initial delay tolerance | ±1.5 ns at +25°C, VCC = 3.3V - sets baseline timing accuracy before environmental drift |
| Delay stability | ±5.0 ns over -40°C to +85°C and 2.7V–3.6V - defines worst-case timing budget in industrial environments |
| Supply voltage | 2.7V–3.6V - compatible with modern 3V logic families and low-power systems |
| Output rise/fall time | 2.0–2.5 ns into 15 pF - ensures clean transitions for >200 MHz edge rates |
| Active supply current | ≤10 mA at VCC = 3.6V, 1 µs period - enables low-power timing in always-on subsystems |
| Input pulse width min | 25 ns (100% of delay) - prevents pulse truncation and ensures full delay integrity |
Pinout & Package
DS1135LZ-25 is housed in an 8-pin SOIC package (150-mil width, outline 21-0041), RoHS-compliant (Z suffix), vapor-phase and IR-reflow solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3 | Dedicated logic inputs | Accept TTL/CMOS-compatible signals; each drives one independent delay path |
| OUT1, OUT2, OUT3 | Buffered delay outputs | Provide 25 ns delayed copies with 2.0–2.5 ns edge transitions into 15 pF |
| VCC | Positive supply | Single 2.7V–3.6V rail powering all three delay paths and buffers |
| GND | Reference ground | Common return for inputs, outputs, and internal circuitry; critical for delay consistency |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates external RC networks or crystal-based solutions, ensuring long-term stability and zero aging drift |
| Precision leading & trailing edge matching | Maintains input duty cycle integrity - essential for clock deskew and symmetric waveform generation |
| Industrial temperature range support | Guaranteed 25 ns delay performance from -40°C to +85°C without derating or calibration |
| 3V-only operation | Optimized for low-voltage logic domains; avoids level-shifting complexity in mixed-supply systems |
| SO-8 footprint compatibility | Enables drop-in replacement for legacy DS1033/DS1035 designs using standard 150-mil SO land patterns |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-in-1 fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1035Z-25+ | Same 25 ns delay, but higher initial tolerance (±3.0 ns) and wider temp drift (±8.0 ns over -40°C to +85°C) | Lower timing precision limits use in high-resolution test or fast data acquisition | Select DS1135LZ-25 when ±5.0 ns total drift is required; DS1035Z-25+ only where looser budget suffices |
| MAX9602ESE+ | Programmable 0–100 ns delay (1 ns steps), higher power (25 mA), SO-16 package | Supports dynamic delay tuning but requires SPI interface and adds firmware overhead | Choose MAX9602ESE+ only if variable delay is mandatory; DS1135LZ-25 preferred for static, low-power, pin-efficient 25 ns alignment |
Compared with DS1035Z-25+ and MAX9602ESE+, DS1135LZ-25 delivers superior delay stability (±5.0 ns vs ±8.0 ns or uncalibrated programmable drift), lower power (10 mA vs 25 mA), and smaller footprint (SO-8 vs SO-16), making it optimal for space-constrained, fixed-delay industrial timing.

FAQ
What is the guaranteed delay accuracy of DS1135LZ-25 over its full operating temperature range?
The DS1135LZ-25 guarantees a total delay variation of ±5.0 ns over -40°C to +85°C and 2.7V–3.6V supply, including both initial tolerance (±1.5 ns) and additional drift due to temperature and voltage changes. This specification is measured at the 1.5V logic threshold for both rising and falling edges, ensuring matched performance across signal polarity.
Can DS1135LZ-25 replace DS1033 in existing designs without layout changes?
Yes, DS1135LZ-25 uses the same 8-pin SOIC (150-mil) package and pinout as DS1033, with identical IN1–IN3, OUT1–OUT3, VCC, and GND assignments. Its 3V operation and improved delay stability make it a recommended drop-in replacement, though designers should verify supply voltage compatibility since DS1033 operated at 5V.
Does DS1135LZ-25 support both rising and falling edge delay with equal precision?
Yes, DS1135LZ-25 specifies identical tPLH (rising edge) and tPHL (falling edge) delays of 25 ns, with matched tolerances. The datasheet confirms leading and trailing edge precision preserves input symmetry - critical for maintaining duty cycle in clock distribution and PWM applications.
What is the minimum input pulse width required for reliable operation of DS1135LZ-25?
The DS1135LZ-25 requires a minimum input pulse width of 25 ns - defined as 100% of its nominal delay value. This ensures the internal delay circuitry fully resolves the input transition; shorter pulses may result in incomplete or undefined output behavior per the AC Electrical Characteristics table.
Is DS1135LZ-25 compatible with lead-free reflow soldering processes?
Yes, DS1135LZ-25 carries the "+" suffix indicating RoHS compliance and lead-free construction. It is qualified for vapor-phase and IR reflow soldering up to +260°C peak temperature (per JEDEC J-STD-020), with a maximum lead temperature of +300°C for 10 seconds during hand soldering.
