Product details
Overview
DS1010S-125/T&R from Dallas Semiconductor (now Maxim Integrated) is a 10-tap all-silicon delay line with nominal total delay of 125 ns, ±5% or ±2 ns tolerance, TTL/CMOS-compatible input/output, and 16-pin SOIC package. It delivers precise leading and trailing edge delays across ten equally spaced taps (12.5 ns per tap), supporting logic timing alignment in high-speed digital systems such as clock skew correction and pulse width adjustment.
For engineers reviewing the DS1010S-125/T&R datasheet, DS1010S-125/T&R pinout, DS1010S-125/T&R application, or DS1010S-125/T&R equivalent, key selection factors include verified tap-to-tap uniformity, guaranteed edge accuracy under 5 V ±5%, drive capability for up to 10 LS-TTL loads, and SOIC-16 surface-mount compatibility with no hybrid component dependencies.
Technical Context
The DS1010S-125/T&R implements a monolithic CMOS delay chain architecture with fixed propagation stages per tap, ensuring deterministic delay increments of 12.5 ns between TAP 1 and TAP 10. Delay accuracy is maintained across temperature (0°C to 70°C) and supply voltage (4.75 V to 5.25 V), with unidirectional drift behavior-i.e., all taps shift consistently under voltage or thermal variation.
It operates with 1.5 V threshold detection for tPLH/tPHL measurement, supports 40 ns minimum input pulse width, and exhibits 5–10 pF input capacitance. Output drive strength meets LS-TTL loading requirements (IOL = 12 mA, IOH = –1 mA), and power consumption remains stable at 40–150 mA active current under full load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total delay (TAP 10) | 125 ns ±5% or ±2 ns - defines maximum fixed latency from IN to final output |
| Delay per tap | 12.5 ns - enables precise sub-cycle timing adjustments in synchronous logic |
| Supply voltage | 4.75 V to 5.25 V - compatible with standard 5 V TTL/CMOS rails without regulation overhead |
| Input threshold | VIH ≥ 2.2 V, VIL ≤ 0.8 V - ensures robust noise margin against 5 V logic transitions |
| Output drive | 12 mA sink / –1 mA source - directly interfaces 10 × 74LS loads without buffer amplification |
| Operating temperature | 0°C to 70°C - validated for commercial-grade embedded control and instrumentation |
| Input capacitance | 5–10 pF - minimizes signal reflection and timing uncertainty on PCB traces |
Pinout & Package
DS1010S-125/T&R uses a 16-pin SOIC (300-mil) package, optimized for surface-mount assembly and reduced board area versus DIP alternatives. Pin assignments are defined per Dallas Semiconductor mechanical drawings and validated for vapor-phase, IR, and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS-compatible signals with 1.5 V switching threshold |
| 2, 3, 5, 6, 8, 9, 11, 12, 14, 15 | TAP 1–TAP 10 | 10 independent delayed outputs; each provides identical 12.5 ns incremental delay from preceding tap |
| 4, 16 | VCC | Primary 5 V supply pins; dual connection reduces IR drop and improves noise immunity |
| 7, 13 | GND | Dual ground terminals; minimize return path inductance for clean edge fidelity |
| 10 | NC | No internal connection; must remain unconnected to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid ceramic delay line reliability risks and enables automated SMT placement |
| Equal tap spacing (12.5 ns) | Enables predictable phase interpolation and multi-point sampling in timing-critical paths |
| Leading/trailing edge accuracy | Guarantees matched tPLH and tPHL within same tolerance window-critical for pulse symmetry |
| Low-power CMOS operation | Reduces thermal load in dense logic arrays while maintaining 125 ns delay integrity |
| Wave/IR/vapor-phase solderable | Validated reflow profile compliance eliminates post-assembly repair risk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1010-125 | 14-pin DIP package; identical electrical specs and 125 ns total delay | Through-hole assembly only; requires larger PCB footprint and manual soldering | Select when legacy DIP layout or hand-soldered prototyping is required |

FAQ
What is the exact total delay specification for DS1010S-125/T&R?
The DS1010S-125/T&R provides a nominal total delay of 125 ns from IN to TAP 10, with accuracy specified as ±5% or ±2 ns, whichever is greater. This tolerance applies to both leading (tPLH) and trailing (tPHL) edge measurements at 25°C and VCC = 5.0 V, and is validated across the full operating temperature range (0°C to 70°C).
Does DS1010S-125/T&R support both rising and falling edge delay accuracy?
Yes, DS1010S-125/T&R guarantees matched delay accuracy for both edges: tPLH (rising) and tPHL (falling) are identical within the same ±5% or ±2 ns tolerance band. This symmetry is achieved through balanced CMOS delay chain design and confirmed in AC Electrical Characteristics tables and Timing Diagram Figure 2.
Can DS1010S-125/T&R drive standard TTL loads directly?
Yes, DS1010S-125/T&R can drive up to 10 LS-TTL loads per tap, as verified by IOL = 12 mA and IOH = –1 mA specifications at VCC = 4.75 V. This eliminates the need for external buffer stages in most 5 V logic interfacing scenarios, including connections to 74LS-series inputs.
What is the package type and lead count of DS1010S-125/T&R?
DS1010S-125/T&R uses a 16-pin SOIC (Small Outline Integrated Circuit) package with 300-mil body width. Pin assignments follow Dallas Semiconductor's official mechanical drawing for DS1010S, including dual VCC (pins 4, 16), dual GND (pins 7, 13), one IN (pin 1), ten TAP outputs (pins 2, 3, 5, 6, 8, 9, 11, 12, 14, 15), and one NC (pin 10).
Is DS1010S-125/T&R compatible with automated SMT assembly processes?
Yes, DS1010S-125/T&R is qualified for vapor-phase, infrared (IR), and wave soldering per manufacturer specifications. Its SOIC-16 footprint and lead finish support standard reflow profiles, and the device has been validated for auto-insertion and pick-and-place handling-making it suitable for high-yield SMT production lines.
