Product details
Overview
DS1135LZ-25+T&R from Maxim Integrated is a 3V, 3-in-1 high-speed silicon delay line delivering precise 25 ns propagation delay on all three independent buffered outputs (tPLH/tPHL = 25/25/25 ns), with ±1.5 ns initial tolerance and ±5.0 ns total tolerance over -40°C to +85°C, used in clock skew management and digital signal alignment in industrial control and test equipment.
For engineers reviewing the DS1135LZ-25+T&R datasheet, DS1135LZ-25+T&R pinout, DS1135LZ-25+T&R application, or DS1135LZ-25+T&R equivalent, key selection criteria include guaranteed edge-aligned delay accuracy, 3.3 V supply compatibility, SO-8 (150-mil) package footprint, and replacement suitability for legacy DS1033-based timing circuits.
Technical Context
The DS1135LZ-25+T&R implements three identical, fully buffered CMOS delay paths in a single monolithic silicon IC, each preserving input signal symmetry via matched leading/trailing edge propagation (tPLH ≈ tPHL). It operates across 2.7 V–3.6 V with no external components required.
Its architecture eliminates quartz-based drift and aging effects while maintaining sub-nanosecond edge fidelity-critical for synchronous sampling, pulse width matching, and deterministic timing in high-reliability embedded systems where thermal stability and reflow compatibility are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 25 ns (tPLH/tPHL), identical across all three outputs for synchronized signal alignment |
| Initial delay tolerance | ±1.5 ns at +25°C, 3.3 V - enables tight setup/hold margin planning without calibration |
| Temp/voltage tolerance | ±5.0 ns over -40°C to +85°C and 2.7 V–3.6 V - ensures stable timing in unregulated industrial environments |
| Supply voltage range | 2.7 V–3.6 V - compatible with modern 3.3 V logic families and low-power system rails |
| Rise/fall time | 2.0–2.5 ns - preserves fast-edge integrity for >100 MHz digital signal paths |
| Power-up time | 1 ms - allows predictable initialization after power-on reset without external sequencing |
Pinout & Package
DS1135LZ-25+T&R is housed in an 8-pin SOIC (150-mil) package, RoHS-compliant, vapor-phase and IR-reflow solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN3 | Dedicated input signals | Three independent TTL/CMOS-compatible inputs accepting 0.0 V–3.0 V pulses; no internal crosstalk coupling |
| OUT1–OUT3 | Buffered delay outputs | Three matched-delay outputs driving 74F04-equivalent loads (15 pF), edge-aligned to inputs |
| VCC | +3V supply rail | Single 2.7 V–3.6 V supply powers all three delay paths; decoupling recommended near pin |
| GND | Ground reference | Common return for all inputs, outputs, and internal circuitry; critical for delay stability |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates quartz aging, shock sensitivity, and frequency drift-ideal for long-life industrial deployments |
| Precision edge matching (tPLH ≈ tPHL) | Maintains input waveform symmetry; prevents duty cycle distortion in clock distribution networks |
| Three independent buffered delays | Enables parallel timing correction of multiple signal paths without external fanout or buffering |
| Lead-free, RoHS-compliant SO-8 package | Supports automated assembly per JEDEC J-STD-020C; compatible with standard 150-mil SO footprints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1033Z-25+ | 5V-only operation (4.5–5.5 V); ±5 ns initial tolerance; wider temp range (-55°C to +125°C) | Requires level-shifting in 3V systems; higher power consumption; legacy support only | Select only if 5V supply and extended temp range are mandatory and 3V compatibility is not required |
| MAX9992ETE+ | Programmable delay (1–100 ns in 1 ns steps); 3.3 V operation; TQFN-16 package | Offers fine-grained adjustment but requires SPI configuration; no pin compatibility with DS1135LZ-25+T&R | Choose when dynamic delay tuning is needed and board redesign is acceptable |
Compared with DS1033Z-25+, DS1135LZ-25+T&R delivers tighter delay accuracy and lower voltage operation in the same SO-8 footprint; versus MAX9992ETE+, it offers fixed, zero-config delay with simpler integration but no programmability.

FAQ
What is the guaranteed delay accuracy of DS1135LZ-25+T&R over its full operating temperature range?
The DS1135LZ-25+T&R guarantees ±5.0 ns total delay variation (tPLH/tPHL) across -40°C to +85°C and 2.7 V–3.6 V supply, including initial tolerance, temperature drift, and voltage sensitivity. This specification is measured at the 1.5 V switching threshold and applies identically to all three outputs of DS1135LZ-25+T&R.
Is DS1135LZ-25+T&R pin-compatible with the DS1033 series?
Yes, DS1135LZ-25+T&R uses the same 8-pin SO (150-mil) package and identical pin assignment (IN1–IN3, OUT1–OUT3, VCC, GND) as DS1033Z-25+, enabling direct PCB-level replacement without layout changes-provided the system operates at 3V instead of 5V.
Does DS1135LZ-25+T&R require external passive components for operation?
No, DS1135LZ-25+T&R is a fully self-contained delay line requiring only a 0.1 µF ceramic decoupling capacitor between VCC and GND. No resistors, capacitors, or crystals are needed-its all-silicon design integrates all timing elements internally.
Can DS1135LZ-25+T&R be used with 2.5 V logic inputs?
Yes, DS1135LZ-25+T&R accepts input voltages from -0.5 V to VCC + 0.5 V, supporting 2.5 V logic levels when powered at 3.3 V. Its VIH (2.0 V min) and VIL (0.8 V max) thresholds ensure reliable recognition of 2.5 V CMOS signals without level translation.
What is the maximum output load capacitance supported by DS1135LZ-25+T&R?
DS1135LZ-25+T&R is characterized for 15 pF load capacitance per output, matching one 74F04 input gate. Driving heavier loads (>20 pF) may degrade rise/fall times and delay accuracy; for such cases, external buffer amplification is recommended to maintain DS1135LZ-25+T&R's specified 2.0–2.5 ns edge performance.
