Product details
Overview
DS1135Z-15+ from Maxim Integrated is a +5V, 3-channel all-silicon delay line with precise 15 ns per-output propagation delay (tPLH/tPHL), ±1.5 ns tolerance over -40°C to +85°C, and leading/trailing edge symmetry preservation for high-speed digital timing alignment in clock distribution and signal deskewing applications.
For engineers reviewing the DS1135Z-15+ datasheet, DS1135Z-15+ pinout, DS1135Z-15+ application, or DS1135Z-15+ equivalent, this device serves as a drop-in replacement for DS1013/DS1035 in industrial control, test equipment, and FPGA interface timing paths requiring stable, low-jitter, temperature-invariant delay with LS-TTL load drive capability.
Technical Context
The DS1135Z-15+ implements three independent buffered delay paths in a single 8-pin SOIC package, each delivering identical 15 ns nominal delay with matched tPLH and tPHL characteristics. Its all-silicon architecture eliminates quartz aging and thermal hysteresis, while internal logic buffering ensures consistent edge fidelity across temperature and supply voltage variations (4.75 V–5.25 V).
Each output drives up to 10 LS-TTL loads with 2.0–2.5 ns rise/fall times and maintains input pulse width integrity-critical for synchronous data capture and setup/hold margin optimization in high-speed digital systems where deterministic latency is mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 15 ns ±1.5 ns over -40°C to +85°C - guarantees deterministic latency for timing-critical signal alignment |
| Supply voltage | +5 V ±5% (4.75 V–5.25 V) - compatible with standard TTL/CMOS logic rails |
| Rise/fall time | 2.0–2.5 ns - supports >200 MHz signal edges without distortion |
| Output drive | 10 LS-TTL loads - enables fanout without external buffers in dense logic interfaces |
| Input capacitance | 10 pF - minimizes loading on upstream drivers and preserves signal integrity |
| Power-up time | 100 ms - defines minimum stabilization delay before valid delay operation begins |
Pinout & Package
DS1135Z-15+ is housed in an 8-pin SOIC (150-mil) package with gull-wing leads, RoHS-compliant, and qualified for vapor phase, IR, and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3 | Digital input signals | Three independent TTL/CMOS-compatible inputs accepting 0.8 V/2.2 V thresholds |
| OUT1, OUT2, OUT3 | Buffered delayed outputs | Three matched 15 ns-delayed outputs, each capable of driving 10 LS loads |
| VCC | Positive supply | +5 V power rail; decoupling required at pin for noise-sensitive timing stability |
| GND | Ground reference | Common return path for all inputs, outputs, and internal circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Precise leading & trailing edge delay | tPLH and tPHL both 15 ns ±1.5 ns - preserves input duty cycle and enables accurate skew correction |
| All-silicon construction | No quartz resonator or MEMS element - eliminates aging, shock sensitivity, and thermal hysteresis |
| Temperature-stable delay | ±1.5 ns variation over -40°C to +85°C - ensures consistent timing in industrial environments |
| LS-TTL load compatibility | Each output drives 10 LS loads - reduces need for external level-shifting or buffering stages |

FAQ
What is the guaranteed delay accuracy of DS1135Z-15+ over its full operating temperature range?
The DS1135Z-15+ guarantees ±1.5 ns delay tolerance over -40°C to +85°C for both tPLH and tPHL. This specification is measured under VCC = 4.75 V–5.25 V and reflects total variation including initial offset, temperature drift, and supply sensitivity-ensuring predictable latency in harsh industrial environments where the DS1135Z-15+ is commonly deployed.
Is DS1135Z-15+ pin-compatible with DS1013 or DS1035?
Yes, DS1135Z-15+ is a direct pin-compatible replacement for DS1013 and DS1035 in the same 8-pin SOIC package. The pin assignment (IN1–IN3, OUT1–OUT3, VCC, GND), footprint, and electrical interface are identical-enabling drop-in upgrades without PCB modification. DS1135Z-15+ improves upon those predecessors with tighter delay tolerance and enhanced temperature stability.
Can DS1135Z-15+ operate from a 3.3 V supply?
No, DS1135Z-15+ is specified only for +5 V operation (4.75 V–5.25 V). For 3 V applications, Maxim recommends the DS1135L family-distinct devices with different internal design and voltage rating. Using DS1135Z-15+ below 4.75 V may result in undefined delay behavior, increased jitter, or failure to meet AC specifications.
What is the maximum capacitive load DS1135Z-15+ can drive while maintaining specified delay and edge performance?
The DS1135Z-15+ is characterized to drive up to 10 LS-TTL loads (equivalent to ~15 pF total load capacitance) while maintaining its 15 ns delay accuracy and 2.0–2.5 ns rise/fall times. Exceeding this load increases propagation delay variation and degrades edge fidelity-so proper termination and load matching are essential when using DS1135Z-15+ in high-fanout configurations.
Does DS1135Z-15+ require external decoupling capacitors?
Yes, DS1135Z-15+ requires a 0.1 µF ceramic decoupling capacitor placed as close as possible to the VCC pin. This is critical to suppress supply-induced jitter and maintain delay stability-especially under fast-switching conditions. The DS1135Z-15+ datasheet specifies that inadequate decoupling directly impacts tPLH/tPHL repeatability and may cause timing violations in systems relying on precise latency.
