Product details
Overview
DS1010S-500 from Dallas Semiconductor (now Maxim Integrated) is a 10-tap all-silicon delay line with fixed 500 ns total delay (50 ns/tap), TTL/CMOS-compatible input/output, 5 V supply, and ±5% or ±2 ns delay tolerance. It delivers precise leading and trailing edge timing for digital signal alignment in test instrumentation and high-speed logic interfaces.
For engineers reviewing the DS1010S-500 datasheet, DS1010S-500 pinout, DS1010S-500 application, or DS1010S-500 equivalent, key selection criteria include tap accuracy over temperature, 16-pin SOIC footprint compatibility with hybrid legacy designs, drive capability (10 × 74LS loads), and dual-edge delay fidelity critical for clock/data deskew and pulse shaping.
Technical Context
The DS1010S-500 implements a monolithic CMOS tapped delay chain with 10 equally spaced outputs, where TAP 10 provides the full 500 ns nominal delay. Delay accuracy is specified as ±5% or ±2 ns (whichever greater) at 25°C, with additional temperature-induced shift of ±2 ns or ±3% over 0°C to 70°C operating range.
All taps reproduce both rising and falling edges with matched propagation characteristics; each output drives up to ten 74LS-type loads while maintaining timing integrity. Input pulse width must be ≥500 ns (per test conditions), and period ≥2 µs for stable operation at the -500 delay grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total delay | 500 ns nominal; defines fixed time offset between IN and TAP 10 output for synchronous signal alignment |
| Delay per tap | 50 ns; enables incremental timing steps for multi-phase sampling or staggered control signals | Delay tolerance | ±5% or ±2 ns (whichever greater); sets worst-case timing budget for system-level setup/hold margining |
| Supply voltage | 5.0 V ±5% (4.75–5.25 V); requires stable LDO or filtered rail to maintain delay stability |
| Output drive | 12 mA sink / –1 mA source; supports direct interface to 74LS logic without buffering |
| Operating temp | 0°C to 70°C; delay shift ≤±2 ns or ±3% across range-critical for industrial-grade timing consistency |
| Input pulse width | ≥500 ns (test condition); minimum width to avoid pulse distortion or tap misalignment |
Pinout & Package
DS1010S-500 uses a 16-pin SOIC (300-mil width) package, surface-mount compatible with vapor phase, IR, and wave soldering processes.

| 11 | TAP 5 | Fifth delay tap output; delivers input signal delayed by 250 ns (5 × 50 ns) |
| 12 | VCC | +5 V power supply; bypass with 0.1 µF ceramic capacitor near pin to suppress switching noise |
| 13 | GND | Ground reference; connect to low-impedance PCB ground plane to minimize delay jitter |
| 14 | TAP 3 | Third delay tap output; delivers input signal delayed by 150 ns (3 × 50 ns) |
| 15 | NC | No connection; electrically isolated-no routing or thermal pad required |
| 16 | NC | No connection; electrically isolated-no routing or thermal pad required |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid ceramic/metal packaging-enables auto-insertion, lower cost, and improved long-term reliability vs. legacy delay lines |
| Leading/trailing edge accuracy | Matched tPLH and tPHL ensures symmetrical delay for both signal transitions-essential for data eye integrity in high-speed interfaces |
| 10 equally spaced taps | Provides deterministic, calibrated timing offsets (50 ns increments) for multi-point signal sampling or phased control generation |
| Low-power CMOS | ICC = 40–150 mA typical; reduces thermal load and simplifies power delivery in dense logic systems |
| TTL/CMOS compatibility | Direct interface with standard logic families without level-shifting-reduces BOM count and layout complexity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1010-500 | 14-pin DIP package; same electrical specs but through-hole mounting; no NC pins at 15/16 | Preferred for prototyping, manual assembly, or legacy DIP-based systems | Select DS1010-500 when board real estate allows and hand-soldering or socketing is required |

FAQ
What is the total delay and tap spacing of the DS1010S-500?
The DS1010S-500 provides a nominal total delay of 500 ns from IN to TAP 10, with 10 equally spaced taps at 50 ns intervals. Each tap (TAP 1 through TAP 10) delivers a cumulative delay of 50 ns × tap number. This fixed, monotonic delay structure is verified across temperature and supply voltage per the device's AC electrical specifications.
Is the DS1010S-500 compatible with TTL and CMOS logic families?
Yes, the DS1010S-500 features TTL/CMOS-compatible input and output voltage thresholds: VIH ≥2.2 V, VIL ≤0.8 V, and output drive of 12 mA sink / –1 mA source. It operates from a 5.0 V ±5% supply and directly interfaces with 74LS, 74HC, and other standard 5 V logic families without level translation.
How does temperature affect the delay accuracy of the DS1010S-500?
Over the 0°C to 70°C operating range, the DS1010S-500 exhibits an additional delay shift of ±2 ns or ±3%, whichever is greater, beyond its base ±5% or ±2 ns room-temperature tolerance. All taps shift unidirectionally with temperature-ensuring relative tap spacing remains preserved for differential timing applications.
What is the maximum capacitive load the DS1010S-500 can drive reliably?
The DS1010S-500 is rated to drive up to ten 74LS-type loads per tap, corresponding to ~10 × 20 pF ≈ 200 pF total load capacitance. Exceeding this may degrade edge rate, increase propagation delay variation, or cause undershoot-especially at higher frequencies or longer traces.
Can the DS1010S-500 be used in place of hybrid delay lines?
Yes-the DS1010S-500 was explicitly designed as a pin-compatible, all-silicon replacement for legacy hybrid delay lines. Its 16-pin SOIC footprint matches mechanical and electrical interface requirements of many DIP-based hybrids, offering improved reliability, lower cost, and simplified assembly while maintaining equivalent timing performance.
