Product details
Overview
MXD1013PA015 from Maxim Integrated is a monolithic 3-channel silicon delay line with independent 15ns nominal delays per channel, ±2ns accuracy (10–60ns range), TTL/CMOS-compatible inputs/outputs, and 8-pin PDIP packaging. It buffers and delays digital signals in clock synchronization and timing-critical digital systems, driving up to ten 74LS loads per output.
For engineers reviewing the MXD1013PA015 datasheet, MXD1013PA015 pinout, MXD1013PA015 application, or MXD1013PA015 equivalent, key selection criteria include guaranteed ±2ns delay tolerance at 15ns, industrial temperature range (−40°C to +85°C), low 20mA active supply current, and compatibility with legacy DS1013-based layouts.
Technical Context
The MXD1013PA015 implements three fully independent, logic-buffered delay paths on a single die, each with matched propagation characteristics. Delay is fixed per variant (here 15ns), calibrated at +25°C with VCC = 5.0V ±5%, and exhibits unidirectional drift across temperature and supply voltage variations.
It features leading- and trailing-edge accuracy (tPLH/tPHL both specified), operates with 0.8V/2.2V input thresholds, and maintains stable performance under capacitive loading-though delay increases with output capacitance due to RC effects on edge rates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Delay | 15ns per channel - fixed, factory-trimmed value for precise timing alignment in synchronous logic. |
| Delay Accuracy | ±2ns (10–60ns range) - ensures sub-nanosecond jitter contribution in clock deskew applications. |
| Supply Voltage | +5.0V ±5% - compatible with standard TTL/CMOS logic rails; operation outside this range degrades delay stability. |
| Active Current | 20mA typical - half the 40mA of Dallas DS1013, reducing thermal load and power supply demand. |
| Output Drive | 10 × 74LS loads - sufficient fanout for direct interfacing with legacy TTL logic without external buffers. |
| Operating Temp | −40°C to +85°C - qualified for industrial environments; delay shift ≤ ±1.5ns or ±3% over full range. |
| Input Compatibility | TTL/CMOS - accepts 0.8V VIH min / 2.2V VIH max; no level-shifting required in mixed-logic systems. |
Pinout & Package
MXD1013PA015 uses an 8-pin plastic DIP (PDIP) package (package code P8-1*, footprint 82 mm²), with 0.3" wide body and 0.1" pin pitch. Pin 1 is marked by notch or dot; device requires 0.1µF local bypass capacitor between VCC and GND.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN1 | First independent input signal - rising/falling edges trigger corresponding OUT1 delay path. |
| 2 | IN2 | Second independent input - electrically isolated from IN1/IN3; enables parallel multi-signal delay. |
| 3 | IN3 | Third independent input - supports triple-channel timing alignment without external gating. |
| 4 | GND | Digital ground reference - must be low-impedance; shared return for all inputs and outputs. |
| 5 | OUT3 | Delayed output for IN3 - 15ns delay relative to IN3 edge; buffered to drive 74LS loads. |
| 6 | OUT2 | Delayed output for IN2 - identical delay spec and drive strength as OUT1/OUT3. |
| 7 | OUT1 | Delayed output for IN1 - primary timing channel; matches DS1013 pinout for drop-in replacement. |
| 8 | VCC | +5V power supply - must be decoupled locally; noise on VCC directly modulates delay accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Three independent buffered delays | Enables simultaneous, isolated delay of three asynchronous signals without crosstalk or shared path skew. |
| ±2ns delay tolerance (10–60ns) | Meets tight setup/hold margin requirements in high-speed clock distribution and FPGA I/O timing closure. |
| 20mA supply current | Reduces PCB-level power delivery burden and thermal dissipation vs. DS1013 (40mA), easing system thermal design. |
| TTL/CMOS input compatibility | Eliminates need for level translators when interfacing with 3.3V or 5V microcontrollers, FPGAs, or logic families. |
| Leading- and trailing-edge accuracy | Ensures consistent pulse width preservation - critical for clock duty-cycle integrity and data eye alignment. |
Applications
| Clock Synchronization | Digital System Timing Alignment |
|---|---|
|

Use Scenario: Interfacing a modern 3.3V microcontroller GPIO to a legacy 5V TTL peripheral requiring precise strobe timing. IC Role / Device Role / Timing Role: Buffers and delays the 3.3V control signal to match 5V logic timing margins and drive capability. Use Value: Maintains 10× 74LS fanout while preserving edge integrity - avoids signal degradation from passive resistive dividers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1013-15 | Same 15ns nominal delay, but 40mA ICC and no guaranteed ±2ns spec below 25°C; wider delay tolerance (±5% above 100ns). | Legacy hybrid construction; higher thermal drift and lower reliability than monolithic MXD1013PA015. | Select DS1013-15 only if backward compatibility with existing DS1013 footprints and BOMs is mandatory. |
| MXD1013SE015 | Identical 15ns delay and ±2ns accuracy, but in 16-pin narrow SO package; same electrical specs and temp range. | Surface-mount alternative for space-constrained PCBs; requires re-layout but offers better high-frequency EMI performance. | Choose MXD1013SE015 for new designs targeting automated assembly and improved signal integrity at >50MHz. |
Compared with DS1013-15, MXD1013PA015 delivers half the supply current and tighter delay tolerance; versus MXD1013SE015, it offers through-hole mounting for prototyping and ruggedized industrial use-without sacrificing timing precision.

FAQ
What is the exact delay value and tolerance for MXD1013PA015?
The MXD1013PA015 provides a nominal 15ns delay per channel, with a guaranteed tolerance of ±2ns over the full operating temperature range (−40°C to +85°C) and supply voltage (5.0V ±5%). This specification applies to both leading-edge (tPLH) and trailing-edge (tPHL) delays, ensuring consistent pulse width preservation in timing-critical circuits.
Is MXD1013PA015 pin-compatible with DS1013-15?
Yes, MXD1013PA015 uses the same 8-pin PDIP footprint and identical pinout as DS1013-15 (IN1, IN2, IN3, GND, OUT3, OUT2, OUT1, VCC), enabling direct mechanical and electrical replacement without PCB changes. However, MXD1013PA015 improves on DS1013-15 with lower supply current (20mA vs. 40mA) and tighter delay tolerance (±2ns vs. unspecified for DS1013-15).
Does MXD1013PA015 support mixed-voltage interfaces?
Yes, MXD1013PA015 accepts TTL/CMOS logic levels (VIH = 2.2V min, VIL = 0.8V max) and operates from a 5.0V ±5% supply, making it compatible with both 3.3V and 5V controllers when driven via series resistors or level translators. Its outputs swing rail-to-rail and can directly drive 74LS, 74F, or 74HC inputs without additional buffering.
How does temperature affect the delay accuracy of MXD1013PA015?
Over −40°C to +85°C, MXD1013PA015's delay shifts by ≤ ±1.5ns or ±3% (whichever is greater) relative to its +25°C value. All three channels track uniformly-i.e., if OUT1 slows by 1ns, OUT2 and OUT3 slow by the same amount-preserving inter-channel skew. This behavior is internally compensated and documented in the Typical Operating Characteristics plots.
Can MXD1013PA015 drive heavy capacitive loads?
MXD1013PA015 is characterized to drive up to ten 74LS inputs (≈100pF total load). Exceeding this capacitance increases rise/fall times and adds delay uncertainty-typically +0.5ns per 10pF beyond spec. For >100pF loads, add a dedicated buffer (e.g., 74AC04) after MXD1013PA015 to maintain timing integrity and edge fidelity.
