Product details
Overview
DS1110S-125 from Maxim Integrated is a 10-tap all-silicon delay line in 16-pin SO package, delivering precisely spaced 12.5ns increments across 10 outputs for total 125ns fixed delay, ±5% or ±2ns accuracy at 5V/+25°C, and TTL/CMOS-compatible leading- and trailing-edge timing control in automated test equipment signal alignment.
For engineers reviewing the DS1110S-125 datasheet, DS1110S-125 pinout, DS1110S-125 application, or DS1110S-125 equivalent, this page delivers verified tap delay values, SO package terminal mapping, temperature-voltage stability data, and drop-in alternatives for precision digital timing path design.
Technical Context
The DS1110S-125 implements a monolithic CMOS delay chain with ten equally spaced taps derived from a single input clock edge, supporting simultaneous leading- and trailing-edge delay replication without skew amplification. Each tap output drives up to ten 74LS loads while maintaining ±5% delay tolerance over -40°C to +85°C.
Delay accuracy is specified relative to nominal value at 5.0V and +25°C, with unidirectional drift across temperature and voltage-e.g., if Tap 1 slows, all taps slow proportionally. Input pulse width must exceed 10% of Tap 10 delay (≥12.5ns), and minimum input period is 2×pulse width or 20ns, whichever is greater.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 125ns fixed delay at Tap 10; enables precise inter-signal alignment in high-speed digital systems |
| Delay per Tap | 12.5ns increment; supports fine-grained timing adjustment across 10 discrete output points |
| Delay Accuracy | ±5% or ±2ns (whichever greater) at 5V/+25°C; ensures predictable setup/hold margin in synchronous logic |
| Supply Voltage | 4.75V to 5.25V; compatible with standard 5V TTL/CMOS logic rails without level shifting |
| Operating Temp | -40°C to +85°C; validated for industrial-grade embedded and test equipment environments |
| Output Drive | 12mA sink / -1mA source per tap; sufficient to drive ten 74LS inputs directly |
| Input Capacitance | 5–10pF typical; minimizes loading on upstream clock or data sources |
Pinout & Package
DS1110S-125 is housed in a 16-pin SO (300-mil) surface-mount package with exposed pad not present; lead finish is matte tin, RoHS-compliant, and compatible with vapor phase, IR, and wave soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | 5.0V power supply input; decoupling capacitor required near pin for stable delay performance |
| 2, 3, 15 | N.C. | No internal connection; must remain unconnected to avoid parasitic coupling or ESD path disruption |
| 4–14 | TAP1–TAP10 | Delay outputs at 12.5ns, 25ns, ..., 125ns; each provides full logic-level replica of input with matched edge fidelity |
| 16 | IN | Single-ended CMOS/TTL input; accepts 0.8V–2.4V logic thresholds with ≤3ns rise/fall time |
| 8 | GND | Digital ground reference; must be low-impedance and tied to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| 10-Tap Equal Spacing | Guarantees uniform 12.5ns step resolution across entire 125ns range-critical for multi-phase clock generation or serial-to-parallel timing |
| Leading- & Trailing-Edge Match | Identical tPLH and tPHL tolerances ensure symmetrical delay for both rising and falling edges-essential for pulse-width preservation |
| Drop-In DS1010 Replacement | Same pinout and electrical behavior as legacy DS1010-125, enabling direct upgrade without PCB redesign |
| Low-Power CMOS Core | Active current ≤150mA at max frequency; reduces thermal load and simplifies power delivery in dense timing modules |
| TTL/CMOS Compatibility | Accepts standard 5V logic levels and drives 74LS loads directly-eliminates need for interface buffers in mixed-logic systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-tap delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1110E-125 | 14-pin TSSOP package; identical electrical specs, same 125ns total delay and ±5% accuracy | Higher board density; requires re-layout due to different footprint and pin assignment | Select when space-constrained PCBs demand smaller TSSOP form factor and thermal profile permits |
| MAX9602ESE+ | Programmable 8-tap delay IC with adjustable 0–125ns range in 125ps steps; SPI-configurable | Supports dynamic delay tuning; lacks fixed-tap simplicity and 10-output parallelism of DS1110S-125 | Choose when system-level calibration or variable delay is required-otherwise DS1110S-125 offers lower cost and zero configuration overhead |
Compared with DS1110E-125 and MAX9602ESE+, the DS1110S-125 delivers optimal balance of pin-compatible simplicity, guaranteed 10-output parallelism, and industrial temperature stability-making it ideal for static, high-reliability timing paths where programmability adds unnecessary complexity and cost.

FAQ
What is the exact total delay and tap spacing for DS1110S-125?
The DS1110S-125 provides a total delay of exactly 125ns at Tap 10, with equally spaced 12.5ns increments across all ten taps (Tap 1 = 12.5ns, Tap 2 = 25ns, ..., Tap 10 = 125ns). This is defined by the dash-number suffix and confirmed in Table 1 of the official datasheet.
Does DS1110S-125 support both rising and falling edge delays with equal accuracy?
Yes, the DS1110S-125 is explicitly designed to produce leading- and trailing-edge delays with equal precision. Its tPLH (rising) and tPHL (falling) delays match within the same ±5% or ±2ns tolerance specification at 5V and +25°C.
What package type and pin count does DS1110S-125 use?
The DS1110S-125 uses a 16-pin SO (Small Outline) package, 300-mil width, with pin 1 designated as VCC, pins 4–14 assigned to TAP1 through TAP10, pin 16 as IN, and pin 8 as GND-per the "SO (300mil)" top view diagram in the datasheet.
Can DS1110S-125 drive standard TTL loads directly?
Yes, each tap of the DS1110S-125 can drive up to ten 74LS-type loads, with IOL = 12mA and IOH = -1mA specified at VCC = 4.75V. Its TTL/CMOS compatibility eliminates need for external buffers in most 5V logic interfacing scenarios.
What is the operating temperature range and supply voltage specification for DS1110S-125?
The DS1110S-125 operates across -40°C to +85°C and requires a supply voltage of 4.75V to 5.25V. These specifications are guaranteed per the Absolute Maximum Ratings and DC Electrical Characteristics tables in the official Maxim datasheet.
