Product details
Overview
DS1135LZ-12+ from Maxim Integrated is a 3V, 3-in-1 high-speed silicon delay line with three independent buffered outputs, each delivering precisely matched 12ns propagation delay (tPLH/tPHL), ±1.0ns initial tolerance, and ±3.0ns tolerance over -40°C to +85°C. It operates across 2.7V–3.6V, consumes ≤10mA active current, and preserves input signal symmetry via leading/trailing edge accuracy - used in clock skew management and digital timing alignment circuits.
For engineers reviewing the DS1135LZ-12+ datasheet, DS1135LZ-12+ pinout, DS1135LZ-12+ application, or DS1135LZ-12+ equivalent, key selection criteria include guaranteed 12ns delay matching across all three outputs, industrial temperature support, SO-8 (150-mil) package compatibility, and replacement suitability for legacy DS1033-based timing designs.
Technical Context
The DS1135LZ-12+ implements an all-silicon delay architecture with three independent logic-buffered delay paths, each with identical tPLH and tPHL values. Its design ensures sub-nanosecond edge alignment fidelity and maintains output symmetry under voltage variation (2.7V–3.6V) and full industrial temperature range (-40°C to +85°C).
No internal PLL or feedback loop is present; delay is fixed and passive-silicon-based. Power-up time is specified at 1ms, and output rise/fall times are ≤2.5ns into 15pF load - enabling use in high-speed digital systems requiring deterministic, low-jitter signal re-timing without clock regeneration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 12ns (tPLH/tPHL), matched across all three outputs for skew-critical timing alignment |
| Initial delay tolerance | ±1.0ns at +25°C/3.3V - enables precise system-level timing budgeting at power-on |
| Temp/voltage tolerance | ±3.0ns over -40°C to +85°C and 2.7V–3.6V - guarantees stable delay in harsh environments |
| Supply voltage range | 2.7V–3.6V - compatible with modern 3V logic families and low-power embedded systems |
| Active supply current | ≤10mA at 3.6V/1µs period - supports power-constrained board-level integration |
| Output rise/fall time | ≤2.5ns into 15pF - ensures clean transitions for 50MHz+ digital interfaces |
| Power-up time | 1ms - defines minimum reset-to-valid-output latency in cold-start applications |
Pinout & Package
DS1135LZ-12+ is housed in an 8-pin SOIC package (150-mil width, outline 21-0041), RoHS-compliant, vapor-phase and IR-reflow solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3 | Dedicated input signals for each delay path | Accept TTL/CMOS-compatible logic inputs; no internal termination required |
| OUT1, OUT2, OUT3 | Buffered delay outputs with matched propagation | Drive one 74F04-equivalent load; 15pF test condition reflects typical FPGA/CPLD interface |
| VCC | +3V supply rail | Must be decoupled locally; supports 2.7V–3.6V operation with monotonic delay behavior |
| GND | Signal and power ground reference | Shared return for all inputs/outputs; critical for maintaining inter-channel delay match |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates quartz or analog RC dependencies - delivers inherent reliability and zero aging drift |

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 |
|---|---|---|---|
| DS1033Z-12+ | Slower 3V version (max 10MHz input); ±2.5ns temp/voltage tolerance; same SO-8 package | Limited to lower-frequency digital systems; less stable over temperature than DS1135LZ-12+ | Select when cost sensitivity outweighs need for high-speed pulse fidelity and tight delay stability |
| MAX9602ETA+ | Single-channel, 12ns delay; 3.3V-only supply; 6-pin SOT23 package; higher drive strength (±24mA) | Not pin-compatible; requires three devices for triple-delay function; better suited for driving heavy loads | Select when board space allows discrete implementation and higher output current is required |
Compared with DS1033Z-12+ and MAX9602ETA+, the DS1135LZ-12+ uniquely integrates three matched 12ns delays in one SO-8 package with superior temperature stability (±3.0ns vs ±2.5ns) and faster edge handling - making it optimal for compact, high-reliability multi-channel timing alignment.

FAQ
What is the guaranteed delay matching between OUT1, OUT2, and OUT3 on the DS1135LZ-12+?
The DS1135LZ-12+ guarantees identical 12ns propagation delay (tPLH/tPHL) across all three outputs, with ±1.0ns initial tolerance at +25°C/3.3V and ±3.0ns matching over -40°C to +85°C and 2.7V–3.6V. This ensures sub-nanosecond inter-channel skew in real-world operating conditions - critical for synchronized multi-path timing applications.
Does the DS1135LZ-12+ require external termination or biasing for proper operation?
No, the DS1135LZ-12+ does not require external termination or biasing. Inputs (IN1–IN3) accept standard TTL/CMOS logic levels, and outputs (OUT1–OUT3) are internally buffered to drive one 74F04-equivalent load (15pF). Local VCC decoupling is recommended, but no pull-ups, pull-downs, or series resistors are needed for nominal operation per the datasheet test conditions.
Can the DS1135LZ-12+ operate reliably at 2.7V supply voltage?
Yes, the DS1135LZ-12+ is fully specified and tested from 2.7V to 3.6V. At 2.7V, delay remains within ±3.0ns of nominal across -40°C to +85°C, and output drive capability meets 8mA sink/1mA source requirements into 15pF. This makes DS1135LZ-12+ suitable for battery-powered or low-voltage industrial systems where supply headroom is constrained.
Is the DS1135LZ-12+ pin-compatible with the DS1033Z-12+?
Yes, the DS1135LZ-12+ is pin-compatible with the DS1033Z-12+ - both use the same 8-pin SOIC (150-mil) package with identical pin assignments (IN1–IN3, OUT1–OUT3, VCC, GND). However, DS1135LZ-12+ offers improved speed, tighter delay tolerance, and enhanced temperature stability, allowing direct drop-in replacement in most existing DS1033Z-12+ designs without layout changes.
What is the maximum input frequency supported by the DS1135LZ-12+?
The DS1135LZ-12+ supports input pulses with period ≥2× delay value (i.e., ≥24ns minimum period), corresponding to a maximum fundamental frequency of ~41.7MHz. Input pulse width must be ≥100% of delay (≥12ns), and rise/fall times must be ≤3.0ns (20%–80%). These constraints ensure accurate delay measurement and output fidelity per the device's AC characterization methodology.
