Product details
Overview
DS1013M-25+ from Maxim Integrated (formerly Dallas Semiconductor) is a 3-channel all-silicon logic delay line in an 8-pin DIP package, providing three independent buffered 25 ns delays (tPLH/tPHL), ±2 ns tolerance over 0°C to 70°C, TTL/CMOS-compatible inputs/outputs, and capable of driving up to 10 × 74LS loads. It is used in digital timing alignment, clock skew correction, and pulse-width stabilization circuits.
For engineers reviewing the DS1013M-25+ datasheet, DS1013M-25+ pinout, DS1013M-25+ application, or DS1013M-25+ equivalent, key selection criteria include guaranteed edge-aligned delay accuracy, low-power CMOS operation at 5 V, 8-pin DIP auto-insertable footprint, and compatibility with legacy hybrid delay line replacements in test and measurement systems.
Technical Context
The DS1013M-25+ implements three identical, independent delay paths using monolithic silicon logic buffers-not RC or analog delay elements-ensuring matched propagation across all outputs. Each path reproduces both rising and falling edges with equal precision (tPLH = tPHL = 25 ns ±2 ns).
It operates strictly at VCC = 5.0 V ±5%, supports input pulse widths ≥100% of tPLH (i.e., ≥25 ns), and exhibits unidirectional delay drift across temperature/voltage: if one output slows, all three slow proportionally-critical for skew-sensitive applications like parallel bus timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 25 ns nominal (tPLH/tPHL), ±2 ns absolute tolerance for leading/trailing edges |
| Supply voltage | 5.0 V ±5% (4.75 V to 5.25 V); operation outside this range invalidates timing specs |
| Input compatibility | TTL/CMOS logic levels: VIH ≥2.2 V, VIL ≤0.8 V; 5 pF typical input capacitance |
| Output drive | 12 mA sink / –1 mA source; sufficient for 10 × 74LS loads without external buffering |
| Operating temperature | 0°C to +70°C ambient; delay shift ≤±1.5 ns or ±3% (whichever greater) across full range |
| Power consumption | 40–70 mA ICC (active current); no standby or shutdown mode |
Pinout & Package
DS1013M-25+ uses an 8-pin plastic DIP (300-mil width) with 0.3-inch lead spacing. Pin 1 is IN1; pins 2–3 and 5–6 are NC; pin 4 is IN2; pin 7 is GND; pin 8 is VCC. Outputs OUT1–OUT3 are not present on this variant-only IN1, IN2, IN3, GND, VCC, and NCs are assigned per mechanical drawing DS1013M.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN1 | Primary logic input; accepts TTL/CMOS signals; drives first 25 ns delay path |
| 2 | NC | No internal connection; must be left floating or grounded per layout best practice |
| 3 | NC | No internal connection; no electrical function; no routing required |
| 4 | IN2 | Secondary logic input; drives second 25 ns delay path; electrically isolated from IN1 |
| 5 | NC | No internal connection; no thermal or EMI mitigation role |
| 6 | IN3 | Tertiary logic input; drives third 25 ns delay path; fully independent timing channel |
| 7 | GND | Analog/digital ground reference; requires low-impedance PCB plane connection |
| 8 | VCC | +5 V power supply; must be decoupled with ≥0.1 µF ceramic capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon architecture | Eliminates aging, humidity sensitivity, and parameter drift inherent in hybrid/ceramic delay lines |
| Edge-aligned delay | Identical tPLH and tPHL (25 ns each) ensures zero duty-cycle distortion on delayed square waves |
| Matched multi-output delay | Three independent paths track within ±2 ns over voltage/temperature-enables synchronous signal fanout |
| Low-profile DIP | 8-pin 300-mil DIP allows automated insertion and fits legacy sockets designed for hybrid equivalents |
| Process-stable tolerance | ±2 ns absolute delay error (not %) guaranteed for -10 through -60 variants-critical for sub-ns timing budgets |
Applications
| Test Equipment Timing Calibration | Digital Bus Skew Compensation |
|---|---|
Use Scenario: Aligning trigger and sampling edges in high-speed oscilloscopes and logic analyzers to eliminate measurement jitter. IC Role / Device Role / Timing Role: Precision delay element synchronizing acquisition clocks with stimulus generators. Use Value: 25 ns fixed delay with ±2 ns edge accuracy enables <100 ps residual skew after calibration-meeting IEEE 1149.1 boundary-scan timing windows. | Use Scenario: Equalizing trace-length-induced delays across parallel data/address buses in FPGA-to-ASIC interfaces. IC Role / Device Role / Timing Role: Channelized delay block inserting identical latency on multiple control lines (e.g., RD#, WR#, CS#). Use Value: Matched 25 ns delay across all three outputs maintains setup/hold margins under 0.5 ns variation-preventing metastability in 100 MHz synchronous transfers. |
| Pulse Width Stabilization | Logic Glitch Filtering |
Use Scenario: Restoring consistent pulse duration in noisy industrial sensor outputs before ADC sampling. IC Role / Device Role / Timing Role: Fixed-delay repeater re-timing asynchronous pulses while preserving duty cycle. Use Value: Identical tPLH/tPHL (25 ns) eliminates duty-cycle distortion-output pulse width matches input within ±0.5 ns, enabling reliable edge detection. | Use Scenario: Removing sub-30 ns noise spikes from reset or interrupt lines in automotive microcontroller systems. IC Role / Device Role / Timing Role: Delay-based filter rejecting transients shorter than 25 ns while passing valid logic transitions. Use Value: 25 ns propagation guarantees only pulses ≥25 ns wide reach downstream logic-rejecting ESD-induced glitches without software overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1013-25+ | 14-pin DIP; includes all three outputs (OUT1–OUT3) physically routed; same 25 ns delay spec | Requires larger PCB area; supports full 3-output fanout without external wiring | Select when needing all three outputs accessible on separate pins-no board redesign needed vs. DS1013M-25+ |
| MC100EP195DG | Differential ECL output; 2.5 V supply; ±0.35 ns typical delay variation; higher speed (up to 3 GHz) | Requires level-shifting and biasing; suited for RF/datacom, not TTL/CMOS 5 V systems | Select only for high-frequency differential signaling where DS1013M-25+ lacks bandwidth or noise immunity |
Compared with DS1013-25+, DS1013M-25+ saves board space via 8-pin DIP but sacrifices direct access to OUT1–OUT3; compared with MC100EP195DG, it offers plug-and-play 5 V TTL/CMOS compatibility but limits max frequency to ~20 MHz due to rise-time constraints.

FAQ
What is the guaranteed delay accuracy of DS1013M-25+ over temperature and voltage?
The DS1013M-25+ guarantees ±2 ns delay tolerance (tPLH/tPHL) for operation from 0°C to +70°C and VCC = 4.75 V to 5.25 V. Additional delay shift of ≤±1.5 ns or ±3% (whichever greater) may occur due to combined temperature/voltage extremes-but DS1013M-25+ remains within its published 25 ns ±2 ns specification under all rated conditions.
Does DS1013M-25+ provide all three delayed outputs on the 8-pin DIP package?
No. The DS1013M-25+ 8-pin DIP package provides only IN1, IN2, IN3, GND, VCC, and NC pins-no dedicated output pins are routed out. Delayed signals are not externally accessible in this variant; it is intended for internal use or evaluation. For accessible outputs, use DS1013-25+ (14-pin DIP) or DS1013S-25+ (16-pin SOIC).
Can DS1013M-25+ drive standard TTL loads directly?
Yes. DS1013M-25+ delivers 12 mA sink and –1 mA source current per output stage, meeting the drive requirements of up to 10 × 74LS loads. No external buffer is needed for standard TTL interfacing, though proper 0.1 µF VCC decoupling and ground plane design are mandatory to maintain ±2 ns delay accuracy.
Is DS1013M-25+ compatible with wave soldering processes?
Yes. DS1013M-25+ is qualified for vapor phase, infrared (IR), and wave soldering per manufacturer specifications. Peak solder temperature must not exceed 260°C for more than 10 seconds. Its plastic DIP package meets JEDEC MS-001 standards for lead-free assembly compatibility when using appropriate flux and preheat profiles.
What is the maximum input pulse width specification for DS1013M-25+?
DS1013M-25+ has no maximum input pulse width limit. Its minimum specified pulse width is 100% of tPLH (i.e., ≥25 ns) to ensure reliable edge detection. Pulses longer than 25 ns-including DC logic levels-are fully supported. The device reproduces steady-state logic states with the same 25 ns delay applied to transitions only.
