Product details
Overview
DS1135U-12+ from Maxim Integrated is a high-speed, all-silicon 3-channel logic delay line operating at +5V, delivering precise 12ns propagation delay (tPLH/tPHL) per output with ±1.0ns initial tolerance and ±1.5ns variation over -40°C to +85°C. It features independent buffered outputs capable of driving 10 LS loads, leading/trailing edge symmetry preservation, and SOIC-8 (150-mil) packaging for industrial timing alignment applications.
For engineers reviewing the DS1135U-12+ datasheet, DS1135U-12+ pinout, DS1135U-12+ application, or DS1135U-12+ equivalent, this device serves as a drop-in replacement for DS1013/DS1035 in high-reliability digital timing circuits requiring stable nanosecond-level delay matching across temperature and supply voltage variations.
Technical Context
The DS1135U-12+ implements three independent, fully buffered CMOS delay paths within a single SOIC-8 package, each with identical 12ns nominal tPLH/tPHL delay under VCC = 5.0V and TA = +25°C. Its all-silicon architecture eliminates quartz aging and thermal hysteresis, enabling consistent edge alignment in clock distribution and signal skew correction.
It operates across 4.75V–5.25V supply range with 2.0–2.5ns output rise/fall times and supports input pulse widths ≥100% of tap delay (≥12ns). Power-up stabilization completes within 100ms, and input/output timing is referenced to 1.5V switching threshold with 15pF load capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 12ns (tPLH/tPHL), matched across all three channels for skew-critical signal alignment |
| Initial delay tolerance | ±1.0ns at +25°C/5.0V - enables deterministic timing budgeting without calibration |
| Temp/voltage tolerance | ±1.5ns over -40°C to +85°C and 4.75V–5.25V - ensures stable delay in industrial environments |
| Output drive strength | 12mA sink / -1.0mA source at VOL=0.5V/VOH=4V - drives 10 LS-TTL loads directly |
| Rise/fall time | 2.0–2.5ns (20%–80%) - preserves fast-edge integrity for >100MHz pulse applications |
| Supply current | 35mA max at 5.25V/1µs period - low-power operation for multi-delay-line systems |
| Input capacitance | 10pF typical - minimizes loading on upstream drivers and reduces layout sensitivity |
Pinout & Package
DS1135U-12+ is housed in an 8-pin SOIC (150-mil) package with standard JEDEC MS-012AC outline, RoHS-compliant lead finish, and compatibility with vapor phase, IR, and wave soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN2) | Input channel 2 | Accepts TTL/CMOS-compatible logic signal; 10pF input capacitance minimizes reflection risk |
| 2 (GND) | Ground reference | Common return path for all inputs, outputs, and internal circuitry; requires low-inductance PCB connection |
| 3 (IN3) | Input channel 3 | Independent delay path input; electrically isolated from IN1/IN2 to prevent crosstalk-induced jitter |
| 4 (IN1) | Input channel 1 | Primary input terminal; matches pin 1 offset for symmetrical PCB routing in multi-channel layouts |
| 5 (VCC) | +5V supply | 4.75V–5.25V tolerant; requires local 0.1µF ceramic decoupling adjacent to pin |
| 6 (OUT1) | Output channel 1 | 12ns delayed replica of IN1; 12mA sink capability supports direct fanout to multiple LS gates |
| 7 (OUT2) | Output channel 2 | 12ns delayed replica of IN2; matched delay ensures <100ps inter-channel skew at temperature extremes |
| 8 (OUT3) | Output channel 3 | 12ns delayed replica of IN3; buffered output maintains signal integrity into 15pF load |
Key Features
| Feature | Design Value |
|---|---|
| Precise leading & trailing edge delay | Identical tPLH and tPHL (12ns each) preserves input waveform symmetry - critical for clock/data recovery |
| All-silicon construction | No quartz aging, no thermal hysteresis, and full immunity to mechanical shock - ideal for automotive and industrial control |
| Three independent buffered delays | Eliminates need for three discrete delay ICs; reduces BOM count and PCB area by >60% vs. single-channel solutions |
| Industrial temperature range | Guaranteed operation from -40°C to +85°C with ±1.5ns delay stability - suitable for outdoor base stations and motor drives |
| Vapor-phase/IR/wave solder compatible | Withstands reflow profiles up to +260°C and hand-soldering up to +300°C for 10s - supports mixed-technology assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-channel fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1135Z-12+ | Same die, identical 12ns delay and SOIC-8 package; Z suffix denotes same 150-mil SO outline as U variant | No functional difference; Z and U denote identical form-factor and performance - U may reflect updated tape/reel or RoHS marking | Select DS1135Z-12+ if legacy BOM references Z suffix; both are functionally interchangeable in design |
| DS1013-12+ | Slower 12ns version with higher ±3ns temp/voltage tolerance and no leading/trailing edge symmetry guarantee | Lower precision makes it unsuitable for edge-sensitive applications like clock recovery or high-speed sampling | Choose DS1013-12+ only for cost-sensitive, non-critical delay tasks where ±3ns variation is acceptable |
Compared with DS1135Z-12+, the DS1135U-12+ offers identical timing performance but may differ in packaging logistics; versus DS1013-12+, it delivers 2× tighter delay stability and guaranteed edge symmetry - essential for deterministic high-speed digital systems.

FAQ
What is the guaranteed delay accuracy of DS1135U-12+ over its full operating temperature range?
The DS1135U-12+ guarantees ±1.5ns delay variation (tPLH/tPHL) over -40°C to +85°C and 4.75V–5.25V supply, measured at 1.5V switching threshold with 15pF load. This specification is validated per Maxim's production test flow and applies identically to all three outputs. DS1135U-12+ does not require external calibration to meet this spec.
Can DS1135U-12+ replace DS1013-12+ without PCB changes?
Yes - DS1135U-12+ uses the same 8-pin SOIC-150-mil package and pinout as DS1013-12+, enabling direct PCB-level replacement. However, DS1135U-12+ delivers tighter ±1.5ns temperature stability versus ±3ns for DS1013-12+, so timing margins improve without layout modification. DS1135U-12+ also adds leading/trailing edge symmetry not present in DS1013-12+.
What is the maximum capacitive load DS1135U-12+ can drive while maintaining specified delay and edge rates?
DS1135U-12+ is characterized and guaranteed for 15pF total load capacitance per output, including PCB trace and gate input capacitance. Driving >15pF increases tPLH/tPHL by up to 0.3ns/pF and slows rise/fall times beyond 2.5ns, potentially violating setup/hold timing in downstream logic. For heavier loads, add a buffer stage before DS1135U-12+ outputs.
Does DS1135U-12+ support 3.3V operation?
No - DS1135U-12+ is specified only for +5V operation (4.75V–5.25V). For 3V-compatible alternatives, refer to the DS1135L family (e.g., DS1135L-12+), which shares the same 12ns delay and SOIC-8 footprint but uses different internal circuitry optimized for 2.7V–3.6V supply. DS1135U-12+ will not function reliably below 4.75V.
How is power-up timing handled in DS1135U-12+?
DS1135U-12+ requires 100ms after VCC reaches 4.75V to stabilize internal biasing and deliver accurate 12ns delays at all outputs. During this power-up time, outputs remain in high-impedance state until internal regulation completes. No external reset or enable signal is needed - the device self-initializes. DS1135U-12+ does not assert valid delay until tPU expires.
