Product details
Overview
DS1135LZ-30+ from Maxim Integrated is a 3V, 3-in-1 high-speed silicon delay line delivering three independent buffered delays of precisely 30 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 targets timing-critical digital logic interfaces.
For engineers reviewing the DS1135LZ-30+ datasheet, DS1135LZ-30+ pinout, DS1135LZ-30+ application, or DS1135LZ-30+ equivalent, this device serves as a lead-free, RoHS-compliant replacement for DS1033 in clock skew management, FPGA I/O timing alignment, and high-speed serial interface synchronization where sub-nanosecond edge fidelity and stable 30 ns delay are required.
Technical Context
The DS1135LZ-30+ implements an all-silicon delay architecture-no external capacitors or trimming-enabling stable delay performance across voltage (2.7V–3.6V) and temperature (-40°C to +85°C). Its three independent outputs each replicate the same 30 ns propagation delay with matched tPLH and tPHL values.
It features TTL/CMOS-compatible inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and outputs capable of driving one 74F04-equivalent load (8 mA sink, -1 mA source at 2.7 V), with output rise/fall times ≤ 2.5 ns and power-up stabilization within 1 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 30 ns (tPLH/tPHL), identical across all three channels |
| Initial delay tolerance | ±1.5 ns at +25°C, 3.3 V - enables tight setup/hold margin control |
| Temp/voltage tolerance | ±5.0 ns over -40°C to +85°C and 2.7V–3.6V - ensures robust timing in industrial environments |
| Supply voltage | 2.7 V to 3.6 V - compatible with modern 3V logic families and low-power systems |
| Output drive strength | 8 mA sink / -1 mA source at VOL = 0.4 V / VOH = 2.0 V - sufficient for direct 74F04 loading |
| Rise/fall time | ≤ 2.5 ns - preserves signal integrity for >200 MHz pulse trains |
| Power-up time | 1 ms - defines minimum reset-to-operational latency after VCC ramp |
Pinout & Package
DS1135LZ-30+ is housed in an 8-pin SOIC package (150-mil width, package code S8+2, outline 21-0041), RoHS-compliant and reflow-solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3 | Dedicated input signals | Three independent logic-level inputs; each drives its corresponding delay path |
| OUT1, OUT2, OUT3 | Dedicated buffered outputs | Three isolated 30 ns delayed outputs; each matches input edge symmetry |
| VCC | Positive supply | +3V supply rail (2.7V–3.6V range); powers all three delay paths |
| GND | Ground reference | Common return for inputs, outputs, and internal circuitry; critical for delay stability |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates external RC components and calibration; ensures long-term drift-free operation |
| Precision leading/trailing edge matching | tPLH and tPHL both specified at 30 ns ± tolerance - maintains input waveform duty cycle |
| 3-in-1 integrated delay function | Reduces board space and interconnect skew vs. three discrete delay ICs |
| Vapor-phase and IR reflow compatible | Supports automated PCB assembly without thermal damage to timing performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-in-1 fixed-delay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1033Z-30+ | Legacy 5V-only version; 30 ns delay but requires 4.5–5.5 V supply; higher ICC (15 mA typical) | Not suitable for 3V systems; incompatible with modern low-voltage FPGAs or microcontrollers | Select DS1135LZ-30+ for 3V designs; DS1033Z-30+ only if legacy 5V infrastructure remains |
| MAX9992ETA+ | Single-output 30 ns delay; 2.7–5.5 V supply; 3 ns max rise/fall; no multi-output integration | Lacks three independent outputs - requires three units for equivalent functionality | Choose DS1135LZ-30+ when board space, BOM count, or inter-channel matching are critical |
Compared with DS1033Z-30+ and MAX9992ETA+, the DS1135LZ-30+ uniquely delivers triple 30 ns delays in one 3V-compatible SOIC package with guaranteed edge symmetry - reducing component count, supply complexity, and inter-channel skew versus alternatives.

FAQ
What is the exact delay value and tolerance specification for DS1135LZ-30+?
The DS1135LZ-30+ provides a nominal delay of 30 ns on each of its three outputs (tPLH and tPHL), with an initial tolerance of ±1.5 ns at +25°C and 3.3 V. Over the full industrial temperature range (-40°C to +85°C) and supply voltage range (2.7 V to 3.6 V), the total delay variation is guaranteed to remain within ±5.0 ns. This is explicitly confirmed in Table 1 of the official DS1135L datasheet.
Is DS1135LZ-30+ pin-compatible with DS1033Z-30+?
No, DS1135LZ-30+ is not pin-compatible with DS1033Z-30+. Although both are 8-pin SOIC devices with three inputs and three outputs, DS1135LZ-30+ uses a different pin assignment: IN2/GND/IN3/IN1/VCC/OUT1/OUT2/OUT3 (pin 1–8), whereas DS1033Z-30+ assigns GND to pin 4 and VCC to pin 8. Layout reuse is not possible without redesign.
Can DS1135LZ-30+ operate from a 2.5V supply?
No, DS1135LZ-30+ is not specified for 2.5V operation. Its absolute minimum supply voltage is 2.7V, and DC/AC electrical characteristics are guaranteed only between 2.7V and 3.6V. Operation below 2.7V may result in undefined delay behavior, increased jitter, or failure to meet tPLH/tPHL specs - per the "DC Electrical Characteristics" table in the DS1135L datasheet.
Does DS1135LZ-30+ require external termination or load matching?
No, DS1135LZ-30+ does not require external termination. Its outputs are designed to drive one 74F04-equivalent load (15 pF capacitive load, as defined in the "Test Conditions" section), and AC specifications (including tPLH/tPHL and rise/fall times) are validated under that condition. Adding series resistors or parallel termination may alter delay accuracy and is not recommended unless verified per application-specific signal integrity analysis.
What is the maximum input frequency supported by DS1135LZ-30+?
The DS1135LZ-30+ supports input pulse periods down to 2× the delay value (i.e., ≥60 ns period), per the "AC Electrical Characteristics" table specifying tPERIOD ≥ 2(tWI) and tWI ≥ 100% of delay. With a 30 ns delay, this implies reliable operation up to ~16.7 MHz (60 ns period). Input pulses must also meet rise/fall time ≤3.0 ns and 500 ns minimum width per the "Test Conditions" section.
