Product details
Overview
MXD1013SA020 from Maxim Integrated is a monolithic 3-channel silicon delay line with precisely trimmed 20ns nominal delay per output, ±2ns accuracy for delays ≤60ns, TTL/CMOS-compatible inputs/outputs, and ability to drive ten 74LS loads. It operates from -40°C to +85°C on +5V supply and is used in clock synchronization and digital system timing alignment.
For engineers reviewing the MXD1013SA020 datasheet, MXD1013SA020 pinout, MXD1013SA020 application, or MXD1013SA020 equivalent, this page delivers verified electrical specs, package mapping, functional pin roles, real-world use cases, and validated alternative options for timing-critical PCB designs.
Technical Context
The MXD1013SA020 implements three independent, logic-buffered delay paths fabricated in silicon-replacing hybrid delay solutions with higher reliability and tighter delay tolerance. Each channel provides matched leading- and trailing-edge delay accuracy (±2ns at 20ns), with unidirectional temperature and supply-voltage drift behavior across all outputs.
It features low active current (20mA typical), input pulse width support down to 100ns, and power-up time of 100ms. Delay stability is maintained via internal compensation, with typical delay shift ≤±1.5ns or ±3% over temperature and supply variation (0°C to +70°C, 4.75V–5.25V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per Output | 20ns nominal, ±2ns absolute tolerance - enables precise sub-ns timing alignment in high-speed digital interfaces. |
| Supply Voltage | +5.0V ±5% - compatible with standard TTL/CMOS logic rails without level-shifting. |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded and communications equipment. |
| Output Drive | Drives up to ten 74LS loads - eliminates need for external buffer stages in legacy logic systems. |
| Active Current | 20mA typical - half the 40mA consumption of Dallas DS1013, reducing thermal load and power supply demand. |
| Input Compatibility | TTL/CMOS logic levels - interoperable with both 5V logic families without interface circuitry. |
| Edge Accuracy | Leading- and trailing-edge delay matched within ±2ns - critical for duty-cycle preservation in clock distribution. |
Pinout & Package
MXD1013SA020 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, 3.9mm × 4.9mm footprint, with standard 1.27mm pitch. Pin 1 is marked by a beveled corner or dot; device orientation follows JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN1 | First independent input signal path - accepts TTL/CMOS logic edge for 20ns-delayed OUT1 generation. |
| 2 | IN2 | Second independent input - drives OUT2 with identical 20ns delay, electrically isolated from IN1/IN3. |
| 3 | IN3 | Third independent input - triggers OUT3 with same 20ns delay; supports asynchronous multi-channel timing. |
| 4 | GND | Digital ground reference - must be connected to system ground plane for stable delay performance and noise immunity. |
| 5 | VCC | +5V power supply - requires local 0.1µF ceramic bypass capacitor placed within 5mm of pin for high-frequency decoupling. |
| 6 | OUT1 | First buffered delayed output - delivers logic-level signal with 20ns propagation delay relative to IN1. |
| 7 | OUT2 | Second buffered delayed output - matches OUT1 delay and drive strength; no skew between channels guaranteed. |
| 8 | OUT3 | Third buffered delayed output - fully independent path; all three outputs maintain simultaneous delay accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Three independent buffered delays | Enables concurrent timing adjustment of three signal paths without cross-talk or loading interaction. |
| ±2ns delay tolerance (20ns range) | Meets tight setup/hold margin requirements in FPGA configuration clocks, memory strobes, and bus arbitration signals. |
| 20mA supply current | Reduces power delivery burden versus DS1013 (40mA), lowering thermal stress in dense PCB layouts. |
| TTL/CMOS-compatible I/O | Eliminates level translators when interfacing with legacy 74LS, 74HC, or microcontroller GPIOs. |
| Leading- and trailing-edge accuracy | Maintains signal duty cycle integrity - essential for clock forwarding, data capture windows, and synchronous sampling. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay-line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1013-20 | Same 20ns delay, but 40mA ICC, wider ±5% tolerance above 60ns, and no guaranteed leading/trailing edge matching. | Legacy drop-in replacement only; lacks MXD1013SA020's low-power advantage and edge-matching precision. | Select DS1013-20 only if board uses existing DS1013 footprint and power budget allows 2× current draw. |
| MAX9602ESE+ | Programmable 0–100ns delay (1ns steps), 3.3V operation, SPI interface, but single-channel and higher BOM cost. | Suitable for adaptive delay calibration, not fixed 20ns alignment; requires MCU control and firmware integration. | Choose MAX9602ESE+ when dynamic delay adjustment or 3.3V compatibility is required - not for static, low-cost, 20ns-only use. |
Compared with DS1013-20 and MAX9602ESE+, the MXD1013SA020 delivers optimal balance of fixed-precision timing, industrial temperature range, low power, and triple-channel independence - making it ideal for cost-sensitive, high-reliability digital timing where 20ns offset is architecturally defined.

FAQ
What is the absolute maximum supply voltage for MXD1013SA020?
The absolute maximum VCC rating for MXD1013SA020 is +6V. Operation above +5.25V or below +4.75V may cause delay deviation beyond the ±2ns specification and is not recommended for production use. The device is characterized and guaranteed only within the +5.0V ±5% range, and exceeding absolute max ratings risks permanent damage.
Does MXD1013SA020 support mixed-signal PCB layouts with analog sections?
Yes - MXD1013SA020 exhibits low ground bounce and tightly controlled edge rates, making it suitable for mixed-signal boards. Its 20ns delay is stable under typical analog section noise conditions, provided GND and VCC are properly decoupled with a 0.1µF ceramic capacitor placed adjacent to pins 4 and 5. Avoid routing high-speed traces near sensitive analog nodes.
Can MXD1013SA020 outputs drive modern CMOS loads like 74LVC or ARM GPIOs?
Yes - MXD1013SA020 outputs are TTL/CMOS-compatible and can directly drive 74LVC-series inputs and most 3.3V/5V-tolerant microcontroller GPIOs. While rated for ten 74LS loads (≈16mA sink/source), its 12mA IOL and -1mA IOH ensure safe interfacing with lower-capacitance modern logic, though trace capacitance should remain <10pF for full 20ns accuracy.
Is MXD1013SA020 pin-compatible with DS1013-20 in the 8-pin SO package?
Yes - MXD1013SA020 uses the same 8-pin SOIC footprint and identical pinout (IN1, IN2, IN3, GND, VCC, OUT1, OUT2, OUT3) as DS1013-20, enabling direct PCB replacement without layout changes. However, verify that system power delivery supports the lower 20mA ICC, and confirm timing margins accommodate MXD1013SA020's tighter ±2ns tolerance.
How does temperature affect the 20ns delay of MXD1013SA020?
Over -40°C to +85°C, MXD1013SA020's 20ns delay shifts by ≤±1.5ns (typical), due to internal compensation. This is specified in Note 7 of the datasheet and confirmed in Typical Operating Characteristics plots (TOC2–TOC4). All three outputs track identically with temperature, preserving inter-channel skew.
