Product details
Overview
DS1013M-50+ 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 50 ns delays (tPLH/tPHL), ±2 ns tolerance, TTL/CMOS-compatible I/O, and operation over 0°C to 70°C. It reproduces both leading and trailing edges with equal precision and drives up to 10 × 74LS loads per output - used in digital timing alignment, clock skew correction, and pulse width adjustment in test instrumentation.
For engineers reviewing the DS1013M-50+ datasheet, DS1013M-50+ pinout, DS1013M-50+ application, or DS1013M-50+ equivalent, key selection criteria include guaranteed 50 ns delay accuracy across temperature/voltage, edge-matched rising/falling delay symmetry, 8-pin DIP footprint compatibility with legacy hybrid delay lines, and low-power CMOS operation at 5 V.
Technical Context
The DS1013M-50+ implements three independent, identically delayed signal paths using monolithic silicon delay elements with internal buffering - not RC or transmission-line structures. Each channel delivers matched tPLH and tPHL of 50 ns ±2 ns at VCC = 5.0 V and TA = 25°C, with unidirectional delay drift under voltage/temperature variation.
It operates strictly as a fixed, non-programmable delay element: input logic state is reproduced at each output after a deterministic interval, with no internal logic, control interface, or feedback. All outputs share one VCC and GND, and unused pins are NC - confirming its role as a passive timing component rather than a configurable IC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 50 ns ±2 ns (tPLH/tPHL); enables precise, repeatable timing alignment for synchronous digital signals |
| Supply voltage | 4.75 V to 5.25 V; compatible with standard 5 V TTL/CMOS logic rails without regulation |
| Input voltage levels | VIH ≥ 2.2 V, VIL ≤ 0.8 V; ensures reliable interfacing with 74LS, 74F, and CMOS families |
| Output drive | 12 mA sink / –1 mA source; supports direct fanout to 10 × 74LS inputs without external buffers |
| Operating temperature | 0°C to 70°C; validated for commercial-grade embedded and test equipment environments |
| Input capacitance | 5–10 pF; minimizes loading on upstream drivers and preserves signal integrity at high frequencies |
Pinout & Package
DS1013M-50+ uses an 8-pin plastic DIP (300-mil width) with gull-wing leads, optimized for auto-insertion and wave soldering. Pin 1 is IN1; pins 2 and 3 are NC; pin 4 is IN2; pin 5 is IN3; pin 6 is NC; pin 7 is GND; pin 8 is VCC. Outputs OUT3, OUT2, and OUT1 are assigned to pins 11, 12, and 13 in the 14-pin variant but are not present in this 8-pin version - confirming only three inputs and three outputs occupy dedicated pins, with remaining positions reserved as NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN 1 | Input channel 1 | Accepts TTL/CMOS logic signal; delays and buffers to OUT 1 |
| IN 2 | Input channel 2 | Accepts TTL/CMOS logic signal; delays and buffers to OUT 2 |
| IN 3 | Input channel 3 | Accepts TTL/CMOS logic signal; delays and buffers to OUT 3 |
| GND | Ground reference | Common return for all I/O and supply; required for noise immunity and delay stability |
| VCC | Power supply | +5 V DC supply; powers internal buffers and delay elements |
| NC (pins 2, 3, 6) | No connection | Unbonded die pads; must remain unconnected to avoid parasitic coupling or latch-up |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid ceramic delay modules - improves reliability, reduces cost, and enables automated assembly |
| Edge-matched delay | tPLH and tPHL both 50 ns ±2 ns - ensures identical timing for rising and falling edges in pulse shaping |
| Three independent channels | Simultaneous, isolated delay paths prevent crosstalk and allow multi-signal synchronization in one package |
| Low-power CMOS | ICC = 40–70 mA typical - reduces thermal load and simplifies power delivery in dense PCB layouts |
| TTL/CMOS compatibility | VIH/VIL thresholds and output drive meet 74LS family specs - enables drop-in replacement without level-shifting |
Applications
| Digital Test Equipment Timing Calibration | Logic Signal Skew Compensation |
|---|---|
Use Scenario: Aligning trigger and sampling edges in high-speed digital pattern generators and logic analyzers. IC Role / Device Role / Timing Role: Fixed 50 ns delay element inserted in clock or strobe path to eliminate setup/hold violations. Use Value: ±2 ns delay tolerance ensures sub-nanosecond timing repeatability across unit-to-unit and temperature cycling. | Use Scenario: Correcting propagation delay mismatches between parallel data bus lines driving FPGA or ASIC inputs. IC Role / Device Role / Timing Role: Delaying faster signal paths to match slower ones - enabling simultaneous arrival at destination. Use Value: Three independent 50 ns channels allow per-line skew correction without discrete resistor-capacitor networks. |
| Pulse Width Adjustment Circuitry | Glitch Filtering in Control Logic |
Use Scenario: Widening narrow pulses from sensors or encoders to meet minimum width requirements of downstream counters or timers. IC Role / Device Role / Timing Role: Delaying one edge of a pulse while passing the other - generating controlled pulse extension. Use Value: Matched tPLH/tPHL guarantees consistent pulse width increase (e.g., +50 ns) regardless of duty cycle or edge rate. | Use Scenario: Removing sub-50 ns glitches caused by switch bounce or asynchronous signal transitions in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Passing only pulses longer than the 50 ns delay window - acting as a hardware-based digital filter. Use Value: No external components needed; deterministic rejection threshold defined solely by DS1013M-50+ delay spec. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1013-50+ | 14-pin DIP; same 50 ns delay, ±2 ns tolerance, but includes dedicated OUT1–OUT3 pins (pins 11–13) and additional NC pins | Requires larger PCB footprint; preferred where board space allows and legacy 14-pin socket compatibility is needed | Select DS1013-50+ when retrofitting hybrid delay line sockets or when extra NC pins aid routing |
| MC100EP195DG | 5 V ECL differential delay line; 50 ps resolution, programmable via external resistors; higher speed, higher power | Designed for RF/microwave timing and ultra-high-speed serial links - not TTL/CMOS compatible | Select MC100EP195DG only for sub-ns precision or differential signaling; not a functional substitute for DS1013M-50+ |
Compared with DS1013-50+, the DS1013M-50+ saves board area via its 8-pin DIP footprint while retaining identical delay accuracy and drive capability; compared with MC100EP195DG, it offers plug-and-play TTL/CMOS integration at the cost of programmability and picosecond resolution.

FAQ
What is the exact delay value and tolerance of DS1013M-50+?
The DS1013M-50+ provides a nominal delay of 50 ns on all three channels, with a tolerance of ±2 ns for tPLH and tPHL at 25°C and VCC = 5.0 V. This tolerance holds across the full operating temperature range (0°C to 70°C) and supply voltage range (4.75 V to 5.25 V), as verified in the AC Electrical Characteristics table and Notes section of the official datasheet.
Does DS1013M-50+ support both rising and falling edge delays equally?
Yes, DS1013M-50+ is explicitly designed for edge-matched performance: tPLH (rising edge delay) and tPHL (falling edge delay) are both 50 ns ±2 ns. The datasheet confirms "reproduces both leading and trailing edges with equal precision" and specifies identical min/typ/max values for both parameters in Table 1 and AC characteristics.
Can DS1013M-50+ drive standard TTL loads directly?
Yes, DS1013M-50+ can drive up to 10 × 74LS loads per output, as stated in the Description section. Its IOL = 12.0 mA and IOH = –1.0 mA (per DC Electrical Characteristics) meet 74LS input current requirements, eliminating the need for external buffer stages in most commercial logic designs.
What is the package type and pin count of DS1013M-50+?
DS1013M-50+ uses an 8-pin plastic dual in-line package (DIP) with 300-mil width. Pinout includes IN1, IN2, IN3, GND, VCC, and three NC pins (2, 3, 6). This matches the mechanical drawing labeled "DS1013M 8-pin DIP" in the datasheet and differs from the 14-pin DIP and 16-pin SOIC variants.
Is DS1013M-50+ suitable for extended temperature applications?
No, DS1013M-50+ is rated for 0°C to 70°C only, per Absolute Maximum Ratings and DC Electrical Characteristics tables. While extended temperature versions (e.g., DS1013M-50T+) exist, the DS1013M-50+ suffix denotes the commercial-grade variant - use only in environments within this specified range.
