Product details
Overview
DS1135LU-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. It preserves input signal symmetry via leading/trailing edge accuracy and targets timing-critical logic synchronization in industrial control and test equipment.
For engineers reviewing the DS1135LU-25+T&R datasheet, DS1135LU-25+T&R pinout, DS1135LU-25+T&R application, or DS1135LU-25+T&R equivalent, key selection criteria include guaranteed 25 ns delay stability across voltage (2.7–3.6 V) and temperature, 8-pin SOIC (150-mil) package compatibility, and replacement suitability for legacy DS1033-based designs requiring improved edge fidelity and low-power 3V operation.
Technical Context
The DS1135LU-25+T&R implements three fully independent, logic-buffered delay paths within a single monolithic silicon die-no external components required. Each path delivers matched 25 ns propagation delay with identical tPLH and tPHL values, ensuring deterministic skew control between outputs.
It operates strictly at 3V (2.7–3.6 V), uses CMOS-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and guarantees sub-nanosecond edge precision: output rise/fall times are 2.0–2.5 ns into 15 pF load, with power-up stabilization in ≤1 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 25 ns (tPLH/tPHL), matched across all three outputs for synchronized timing paths |
| Initial delay tolerance | ±1.5 ns at +25°C, VCC = 3.3 V - enables tight setup/hold margin planning |
| Temp/voltage tolerance | ±5.0 ns over -40°C to +85°C and 2.7–3.6 V - ensures robustness in industrial environments |
| Supply voltage | 2.7 V to 3.6 V - compatible with modern 3V logic families without level-shifting |
| Output rise/fall time | 2.0–2.5 ns into 15 pF - supports high-speed digital interfaces up to ~200 MHz |
| Active supply current | 10 mA max at VCC = 3.6 V, 1 µs period - low static power for battery-sensitive systems |
| Input capacitance | 10 pF typical - minimizes loading on preceding driver stage |
Pinout & Package
DS1135LU-25+T&R is housed in an 8-pin SOIC package (150-mil width, outline 21-0041), RoHS-compliant (indicated by '+' suffix), vapor-phase and IR-reflow solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3 | Dedicated input signals for each delay channel | CMOS-compatible inputs accepting 0–3.3 V logic; no internal termination required |
| OUT1, OUT2, OUT3 | Buffered delay outputs with matched 25 ns propagation | Drive 74F04-equivalent loads; 2.0–2.5 ns edge rates support clean signal integrity |
| VCC | +3V supply rail | Must be decoupled locally; operates only within 2.7–3.6 V range |
| GND | Ground reference | Common return for all inputs, outputs, and supply; critical for delay stability |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates aging, drift, and environmental sensitivity inherent in RC or analog delay solutions |
| Precision leading/trailing edge matching | Maintains input waveform symmetry - essential for clock distribution and data strobing |
| Three independent buffered delays | Enables parallel timing paths without cross-talk or shared loading effects |
| Industrial temperature range support | Guaranteed 25 ns delay performance from -40°C to +85°C - suitable for harsh environments |
| Tape-and-reel packaging | Optimized for automated SMT assembly; 'T&R' suffix confirms reel format availability |
Applications

Use Scenario: Synchronizing fast-response sensor inputs (e.g., encoder quadrature edges) before feeding into real-time motion controllers. IC Role / Device Role / Timing Role: Low-jitter delay buffer preserving edge fidelity for deterministic interrupt timing. Use Value: Leading/trailing edge accuracy prevents duty-cycle distortion; 10 mA ICC enables direct integration into 3V PLC I/O modules. | Use Scenario: Compensating for fixed interconnect skew between parallel data lanes in LVDS or CMOS bus interfaces. IC Role / Device Role / Timing Role: Matched 25 ns delay applied to selected lanes to realign sampled data at receiver. Use Value: Three independent outputs allow per-lane adjustment without external buffering; SOIC footprint simplifies board layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar delay-line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1135LZ-25+ | Same die, identical 25 ns delay specs, but packaged in standard SO (S8+2); DS1135LU-25+T&R specifies tape-and-reel delivery format | No functional difference; U-suffix denotes tape-and-reel packaging per Maxim ordering convention | Select DS1135LU-25+T&R for SMT production; DS1135LZ-25+ for sample or manual assembly |
| MAX9602ESE+ | Single-output, 25 ns delay; higher ICC (15 mA), wider VCC range (2.7–5.5 V); different SO-8 pinout | Lacks triple-output capability; requires three devices for equivalent functionality | Choose only if mixed-voltage system design demands 5V compatibility or single-channel isolation is preferred |
Compared with DS1135LZ-25+, DS1135LU-25+T&R offers identical electrical performance but optimized logistics for volume SMT use; versus MAX9602ESE+, it provides integrated triple-delay functionality in one SO-8 package, reducing board area and component count by 67%.

FAQ
What is the exact delay value and tolerance of DS1135LU-25+T&R?
The DS1135LU-25+T&R delivers precisely 25 ns propagation delay on each of its three outputs (tPLH/tPHL = 25/25/25 ns). Initial tolerance is ±1.5 ns at +25°C and 3.3 V; total tolerance over -40°C to +85°C and 2.7–3.6 V is ±5.0 ns. These values are guaranteed per Maxim's datasheet Table 1 and apply identically to all three channels.
Is DS1135LU-25+T&R pin-compatible with DS1033?
DS1135LU-25+T&R is specified as a recommended replacement for DS1033, but it is not pin-compatible: DS1033 uses a 14-pin DIP or SO package with different pin assignments and delay architecture. DS1135LU-25+T&R uses an 8-pin SOIC (150-mil) with dedicated IN1–IN3/OUT1–OUT3 pins. PCB redesign is required for migration.
Does DS1135LU-25+T&R support 5V operation?
No. DS1135LU-25+T&R is strictly a 3V device with absolute maximum VCC of +6.0 V but operational specification limited to 2.7–3.6 V. Applying 5V violates DC electrical characteristics and may damage the device. For 5V systems, consider discrete delay solutions or level-shifted interface designs.
What does the 'U' in DS1135LU-25+T&R signify?
The 'U' suffix in DS1135LU-25+T&R indicates tape-and-reel packaging per Maxim's ordering nomenclature. It denotes the same silicon and electrical specifications as DS1135LZ-25+, but supplied in automated assembly-ready format. The '+' confirms RoHS compliance; 'T&R' explicitly confirms tape-and-reel delivery.
Can DS1135LU-25+T&R drive standard TTL or CMOS loads?
Yes. DS1135LU-25+T&R outputs are designed to drive one 74F04-equivalent load (≈20 pF, 1 mA sink/source), with guaranteed VOL ≤ 0.4 V and VOH ≥ 2.0 V under specified conditions. Its 2.0–2.5 ns rise/fall times and 10 mA drive strength make it compatible with 74LVC, 74ALVC, and most 3V CMOS families without external buffering.
