Product details
Overview
MXD1013UA050 from Maxim Integrated is a monolithic 3-channel silicon delay line with precise, independent 50ns delays per output (OUT1/OUT2/OUT3), ±2ns accuracy (10–60ns range), TTL/CMOS-compatible inputs, and 20mA active supply current. It operates from -40°C to +85°C and drives up to ten 74LS loads - used in clock synchronization and digital system timing alignment.
For engineers reviewing the MXD1013UA050 datasheet, MXD1013UA050 pinout, MXD1013UA050 application, or MXD1013UA050 equivalent, key selection factors include guaranteed 50ns nominal delay tolerance, µMAX-8 package footprint compatibility, input-to-output edge accuracy (leading & trailing), and drop-in replacement capability for DS1013-series delay lines in space-constrained digital timing circuits.
Technical Context
The MXD1013UA050 implements three independent, logic-buffered analog delay paths on a single die, each with matched propagation characteristics and unidirectional temperature/supply drift behavior. Delay stability is maintained via internal compensation across VCC = 4.75V–5.25V and full industrial temperature range.
Each channel features identical input threshold levels (VIL = 0.8V, VIH = 2.2V), 1.5V switching reference for tPLH/tPHL measurement, and low-capacitance inputs (CIN = 5pF typical). Output drive strength supports fan-out to ten 74LS gates without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Delay | 50ns per output (OUT1/OUT2/OUT3), verified at VCC = 5.0V, TA = +25°C |
| Delay Accuracy | ±2ns (10–60ns range), enabling sub-nanosecond jitter control in clock deskew |
| Supply Voltage | +5.0V ±5% - compatible with standard TTL/CMOS logic rails |
| Active Current | 20mA typical - half the 40mA of Dallas DS1013, reducing thermal load |
| Input Compatibility | TTL/CMOS logic levels (VIL ≤ 0.8V, VIH ≥ 2.2V) - direct interface with 74LS/F series |
| Output Drive | Drives ≥10 standard 74LS loads - eliminates need for external buffers in most applications |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded timing systems |
Pinout & Package
The MXD1013UA050 is housed in an 8-pin µMAX package (1.6mm × 3.0mm, 0.5mm pitch), optimized for high-density PCB layouts and thermally efficient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN1 | First independent delay input - accepts TTL/CMOS logic signal for OUT1 path |
| 2 | IN2 | Second independent delay input - enables parallel timing alignment of separate signals |
| 3 | IN3 | Third independent delay input - supports triple-signal deskew in multi-clock domains |
| 4 | GND | Device ground reference - must be low-impedance connection for delay stability |
| 5 | VCC | +5V power supply - requires local 0.1µF bypass capacitor per layout guidelines |
| 6 | OUT1 | First delayed output - delivers 50ns-delayed replica of IN1 with leading/trailing edge fidelity |
| 7 | OUT2 | Second delayed output - delivers 50ns-delayed replica of IN2, matched to OUT1 within ±2ns |
| 8 | OUT3 | Third delayed output - delivers 50ns-delayed replica of IN3, fully independent and synchronized |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1013S-50 | 14-pin DIP, 40mA ICC, ±3% delay tolerance (vs. ±2ns), no µMAX option | Requires larger board area and higher power; not suitable for high-density or low-power designs | Select DS1013S-50 only if legacy DIP footprint or second-source qualification is mandatory |
| MXD1013SA050 | 8-pin SO package (same delay, same specs), 3.9mm × 4.9mm vs. µMAX's 1.6mm × 3.0mm | Larger footprint and higher thermal resistance; less suitable for ultra-compact layouts | Choose MXD1013SA050 when SO-8 reflow compatibility or existing SO padstacks are prioritized over size |
Compared with DS1013S-50 and MXD1013SA050, the MXD1013UA050 delivers identical 50ns delay performance in the smallest available package with lowest power consumption - making it optimal for next-generation miniaturized timing-critical systems where board space and thermal budget are constrained.

FAQ
What is the exact nominal delay value specified for MXD1013UA050?
The MXD1013UA050 is factory-trimmed to deliver a nominal 50ns delay on all three outputs (OUT1, OUT2, OUT3) under standard conditions (VCC = 5.0V, TA = +25°C). This value is confirmed in the "Part Numbers and Delay Times" table and validated by timing characterization data showing ±2ns accuracy in the 10–60ns range.
Does MXD1013UA050 support both rising and falling edge delay accuracy?
Yes, the MXD1013UA050 guarantees leading-edge (tPLH) and trailing-edge (tPHL) delay accuracy within ±2ns for its 50ns nominal delay, as explicitly stated in the datasheet's Timing Characteristics section and verified in the Test Conditions using 1.5V-level measurements on both edges.
Is MXD1013UA050 pin-compatible with DS1013-series devices?
No - MXD1013UA050 uses an 8-pin µMAX package with a 1×3 input / 1×3 output / VCC / GND pinout, while DS1013 variants use 14-pin DIP or 16-pin SO packages with different pin assignments. However, MXD1013UA050 is a functional replacement with identical delay specification and improved electrical performance.
What is the maximum capacitive load the outputs of MXD1013UA050 can drive without degrading delay accuracy?
The MXD1013UA050 is characterized to drive up to ten standard 74LS inputs (≈15pF total load) while maintaining specified delay accuracy. Exceeding this load increases rise/fall times and introduces additional delay variation - layout best practices recommend minimizing trace capacitance and avoiding sockets or wire-wrap.
Can MXD1013UA050 operate reliably at 4.75V supply voltage?
Yes - the MXD1013UA050 is fully specified over VCC = 4.75V to 5.25V. At 4.75V, output drive strength (IOH/IOL), delay stability (±2ns maintained), and input thresholds remain within datasheet limits, with typical delay shift < ±1.5ns relative to 5.0V operation per Note 7.
