Product details
Overview
DS1005S-60+ from Dallas Semiconductor is a 5-tap all-silicon delay line with fixed tap delays of 12 ns, 24 ns, 36 ns, 48 ns, and 60 ns; ±2 ns or ±3% delay tolerance; TTL/CMOS-compatible input/output; 5 V supply; and 16-pin SOIC package. It reproduces logic levels at each tap with leading and trailing edge accuracy for timing alignment in digital signal paths.
For engineers reviewing the DS1005S-60+ datasheet, DS1005S-60+ pinout, DS1005S-60+ application, or DS1005S-60+ equivalent, key selection factors include tap delay precision, edge fidelity across temperature (0°C to 70°C), drive capability (10 × 74LS loads per tap), low-power CMOS operation, and compatibility with existing DIP/SOIC board layouts.
Technical Context
The DS1005S-60+ implements a monolithic silicon delay structure-not RC or analog-ensuring deterministic, repeatable propagation delays across all five taps. Delay accuracy is specified at ±2 ns or ±3%, whichever is greater, under 0°C to 70°C and VCC = 5.0 V ±5%.
All taps maintain identical edge fidelity: tPLH and tPHL are both defined per Table 1 and match within tolerance; output transitions track input edges without skew inversion. Each tap drives up to ten 74LS loads while maintaining valid VOH/VOL levels under DC electrical specs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| TAP 1 Delay | 12 ns - precise first-stage timing reference for pipeline synchronization |
| TAP 5 Delay | 60 ns - final stage delay enabling 48 ns inter-tap spacing for clock/data deskew |
| Delay Tolerance | ±2 ns or ±3% - ensures worst-case timing budget compliance in high-speed logic interfaces |
| Supply Voltage | 4.75–5.25 V - supports standard 5 V TTL/CMOS rails with ±5% regulation margin |
| Output Drive | 12 mA sink / –1 mA source - sufficient for direct interfacing to 74LS families without buffers |
| Input Capacitance | 5–10 pF - minimizes loading on preceding driver, preserving signal integrity in dense routing |
| Operating Temp | 0°C to 70°C - validated for commercial-grade embedded control and instrumentation systems |
Pinout & Package
DS1005S-60+ is housed in a 16-pin SOIC (300-mil) package with gull-wing leads, compatible with vapor phase, IR, and wave soldering processes. Pin 1 is marked by a notch or dot; device is auto-insertable and tape-and-reel ready.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS-compatible signals with 2.2 V VIH min |
| 2–3, 6, 8–10, 12 | NC | No internal connection; must be left unconnected or tied to GND/VCC per layout best practice |
| 4 | TAP 2 | Second delayed output (24 ns); full logic-level reproduction with edge fidelity |
| 5 | TAP 4 | Fourth delayed output (48 ns); matches TAP 2/TAP 3/TAP 5 delay monotonicity |
| 7 | GND | Digital ground reference; requires low-impedance PCB plane for noise immunity |
| 11 | TAP 5 | Fifth delayed output (60 ns); highest-delay tap, used for maximum deskew or pulse shaping |
| 13 | TAP 3 | Third delayed output (36 ns); center tap enabling symmetric delay interpolation |
| 14 | TAP 1 | First delayed output (12 ns); minimal latency tap for fine-grained timing adjustment |
| 15 | VCC | +5 V power supply; bypass capacitor (0.1 µF) required near pin for stable operation |
| 16 | NC | No internal connection; electrically isolated; no routing or termination needed |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay structure | Eliminates hybrid component drift and aging; guarantees long-term delay stability over 10+ years |
| Leading & trailing edge accuracy | Enables precise pulse width preservation across all taps-critical for strobe/gating applications |
| 5-tap equal spacing (12 ns steps) | Supports incremental delay tuning for serial-to-parallel conversion or multi-phase clock generation |
| 10 × 74LS load drive per tap | Reduces need for external fanout buffers in legacy TTL-based systems |
| Low-power CMOS design | Typical ICC = 40–70 mA enables use in thermally constrained enclosures without forced cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1005-60+ | 14-pin DIP package; same delay values and electrical specs; NC pins differ in count and position | Through-hole assembly; less suitable for high-density SMT boards | Select DS1005S-60+ for SOIC-based designs requiring surface-mount compatibility and automated placement. |
| DS1005M-60+ | 8-pin DIP package; reduced pin count; IN, TAP1–TAP5, VCC, GND only-no NC pins | Space-constrained through-hole applications; limited routing flexibility due to missing NC isolation | Choose DS1005M-60+ only when board real estate is critical and NC pin decoupling is not required. |

FAQ
What is the exact delay value for TAP 3 on DS1005S-60+?
The DS1005S-60+ delivers a nominal 36 ns delay at TAP 3, consistent with its dash-number designation and Table 1 in the official datasheet. This value is guaranteed within ±2 ns or ±3%, whichever is greater, across 0°C to 70°C and VCC = 5.0 V ±5%. The DS1005S-60+ maintains monotonic delay progression: TAP 1 (12 ns), TAP 2 (24 ns), TAP 3 (36 ns), TAP 4 (48 ns), TAP 5 (60 ns).
Is DS1005S-60+ pin-compatible with DS1005-60+?
No, DS1005S-60+ is not pin-compatible with DS1005-60+. DS1005S-60+ uses a 16-pin SOIC footprint with specific NC pin placements (pins 2–3, 6, 8–10, 12, 16), whereas DS1005-60+ uses a 14-pin DIP with different NC assignments. While both share identical delay values and logic behavior, PCB layout changes are required to migrate between packages. The DS1005S-60+ pinout is optimized for SMT routing isolation.
Can DS1005S-60+ operate at 3.3 V?
No, DS1005S-60+ is specified only for 5.0 V ±5% operation (4.75–5.25 V). Its VIH minimum is 2.2 V and VIL maximum is 0.8 V-designed for TTL/CMOS 5 V logic families. Operation at 3.3 V falls outside absolute maximum ratings and violates DC electrical specifications; output drive strength, delay accuracy, and edge fidelity are not characterized or guaranteed below 4.75 V.
Does DS1005S-60+ support both rising and falling edge delays?
Yes, DS1005S-60+ provides matched delay accuracy for both edges: tPLH (rising edge) and tPHL (falling edge) are independently specified in Table 1 and exhibit identical nominal values (e.g., 60 ns for TAP 5) with the same ±2 ns or ±3% tolerance. This dual-edge fidelity preserves pulse width integrity-essential for gating, strobing, and synchronous sampling applications.
What is the maximum capacitive load per tap on DS1005S-60+?
The DS1005S-60+ is rated to drive up to ten 74LS loads per tap, equivalent to ~10 × 20 pF = 200 pF total load capacitance under typical conditions. Exceeding this load may degrade tPLH/tPHL accuracy, increase rise/fall times, or cause VOH/VOL violations. For heavier loads, buffer amplifiers (e.g., 74ACT series) should be used-especially in high-speed or long-trace scenarios.
