Product details
Overview
DS1010S-125 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 deskewing and pulse shaping.
For engineers reviewing the DS1010S-125 datasheet, DS1010S-125 pinout, DS1010S-125 application, or DS1010S-125 equivalent, key selection criteria include tap-to-tap delay accuracy, edge fidelity under temperature variation (±2 ns or ±3% shift for ≥100 ns devices), drive capability (10 × 74LS loads), and SOIC footprint compatibility with hybrid legacy designs.
Technical Context
The DS1010S-125 implements a monolithic CMOS tapped delay chain with fixed 12.5 ns inter-tap spacing and guaranteed delay matching across all 10 outputs. Its architecture ensures identical propagation characteristics for rising and falling edges, with tPLH and tPHL both specified at 125 ns (TAP 10) under VCC = 5.0 V ± 5% and TA = 25°C.
Delay stability is maintained over 0°C to 70°C operating range, with temperature-induced shift bounded at ±2 ns or ±3% (whichever greater) for TAP 10 due to unidirectional drift - all taps slow or speed together. Input pulse width must exceed 40% of TAP 10 tPLH (≥50 ns), and rise/fall times are limited to ≤3.0 ns for specified accuracy.

Pinout & Package
DS1010S-125 uses a 16-pin SOIC (300-mil) package with exposed pad not present; pin assignments are defined per Dallas Semiconductor mechanical drawing DS1010S. Pin 1 is IN, pins 2–11 are TAP 1 through TAP 10 (in non-sequential physical order), pin 12 is VCC, pin 13 is GND, and pins 14–16 are NC.
| Pin/Terminal | Circuit Role | Design Meaning |

| 4 | TAP 8 | Eighth delay output (100 ns); used for mid-range timing calibration points |
| 5 | TAP 6 | Sixth delay output (75 ns); provides symmetric delay relative to center tap |
| 6 | TAP 1 | First delay output (12.5 ns); lowest-latency tap for minimal skew correction |
| 7 | TAP 7 | Seventh delay output (87.5 ns); supports multi-stage pipeline synchronization |
| 8 | TAP 10 | Final delay output (125 ns); primary reference point for total delay specification |
| 9 | TAP 9 | Ninth delay output (112.5 ns); enables sub-125 ns interpolation via dual-tap selection |
| 10 | TAP 5 | Fifth delay output (62.5 ns); commonly used for clock/data alignment in latch-based systems |
| 11 | TAP 3 | Third delay output (37.5 ns); bridges early and mid-range timing windows |
| 12 | VCC | 5 V power supply; requires local 0.1 µF ceramic decoupling |
| 13 | GND | Ground reference; shared return path for all inputs and outputs |
| 14–16 | NC | No connection; left floating per design - no internal bonding or circuitry |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1010-125 | 14-pin DIP package; identical electrical specs but larger footprint and through-hole mounting | Preferred for prototyping, legacy board rework, or mixed-technology assemblies requiring DIP sockets | Select DS1010-125 when board layout or assembly process mandates through-hole components. |
| MAX5517ETP+ | 16-pin TQFN; 125 ns delay with ±1.5 ns accuracy, lower power (ICC < 10 mA), but only single output | Used where single calibrated delay suffices and ultra-low power or space-constrained layouts dominate | Select MAX5517ETP+ only if single-output operation and sub-2 ns accuracy justify higher unit cost and loss of multi-tap flexibility. |
Compared with DS1010-125 and MAX5517ETP+, DS1010S-125 uniquely balances surface-mount efficiency, 10-output versatility, and proven ±2 ns edge fidelity - making it optimal for production systems needing scalable, calibrated delay distribution without redesigning layout or firmware.

FAQ
What is the total delay and tap spacing for DS1010S-125?
The DS1010S-125 provides a total delay of 125 ns at TAP 10, with exactly 12.5 ns spacing between consecutive taps. This is confirmed in Table 1 of the Dallas Semiconductor datasheet, where the dash number "-125" directly specifies the TAP 10 delay, and the device features 10 equally spaced taps. All delays are measured at the 1.5 V threshold under VCC = 5.0 V and TA = 25°C.
Is DS1010S-125 pin-compatible with the through-hole DS1010-125?
No, DS1010S-125 is not pin-compatible with DS1010-125. The DS1010S-125 uses a 16-pin SOIC package with a specific pinout (e.g., IN on pin 1, TAP 1 on pin 6), whereas DS1010-125 uses a 14-pin DIP with different pin assignments (e.g., IN on pin 1, TAP 1 on pin 14). Physical layout and terminal mapping differ; board redesign is required for substitution.
What is the maximum output load drive capability of DS1010S-125?
Each tap of DS1010S-125 can drive up to 10 standard 74LS TTL loads, corresponding to an IOL of 12 mA (low-level) and IOH of –1 mA (high-level) under VCC = 4.75 V. This is specified in the DC Electrical Characteristics table and verified with open-circuit measurement conditions. Exceeding this load may degrade delay accuracy and edge fidelity.
Does DS1010S-125 support both rising and falling edge delays with equal accuracy?
Yes, DS1010S-125 guarantees matched leading-edge (tPLH) and trailing-edge (tPHL) delays within ±2 ns or ±5%, whichever is greater. This is explicitly stated in the FEATURES section and confirmed in Notes 3 and 7 of the datasheet, which emphasize identical propagation behavior for both edges and unidirectional temperature drift across all taps.
What is the operating temperature range and delay stability of DS1010S-125?
DS1010S-125 operates from 0°C to 70°C. For devices with TAP 10 delay ≥100 ns (including DS1010S-125), temperature variation from 25°C to 0°C or 70°C introduces additional delay shift of ±2 ns or ±3%, whichever is greater. This shift affects all taps uniformly, preserving inter-tap spacing and monotonicity as confirmed in Note 5.
