Product details
Overview
DS1110S-250+ from Maxim Integrated is a 10-tap all-silicon delay line in 16-pin SO package, delivering precisely spaced 25ns increments (250ns total delay), ±5% or ±2ns accuracy at 5V/+25°C, TTL/CMOS compatibility, and leading/trailing-edge matching for timing alignment in digital signal paths. It serves as a drop-in replacement for DS1010 in clock deskew and pulse shaping circuits.
For engineers reviewing the DS1110S-250+ datasheet, DS1110S-250+ pinout, DS1110S-250+ application, or DS1110S-250+ equivalent, key selection criteria include tap spacing consistency, edge-matched delay tolerance, load drive capability (10× 74LS), industrial temperature range (-40°C to +85°C), and SO package compatibility with automated assembly.
Technical Context
The DS1110S-250+ implements a monolithic CMOS delay chain with ten fixed, equally spaced taps-each outputting the input logic state after an incremental 25ns delay, culminating in 250ns at Tap 10. Delay stability is maintained across voltage (4.75V–5.25V) and temperature (-40°C to +85°C), with unidirectional drift behavior ensuring monotonic tap-to-tap variation.
It supports both rising- and falling-edge delay measurement at the 1.5V threshold, with specified tPLH/tPHL tolerances of ±4ns (≤40ns delays) or ±13% (＞40ns delays) over full temperature range, and requires no external components for operation beyond standard decoupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 250ns nominal at Tap 10; enables precise pulse positioning for setup/hold margin adjustment. |
| Delay per Tap | 25ns fixed increment; allows stepwise timing calibration without interpolation. |
| Delay Accuracy | ±5% or ±2ns (whichever greater) at 5V/+25°C; ensures predictable skew control in synchronous systems. |
| Operating Voltage | 4.75V to 5.25V; compatible with standard 5V TTL/CMOS logic rails and noise margins. |
| Temperature Range | -40°C to +85°C; validated for industrial-grade embedded and test equipment environments. |
| Output Drive | 10× 74LS loads per tap; eliminates need for buffer stages in moderate-fanout applications. |
| Input Capacitance | 5–10pF typical; minimizes loading on preceding driver and preserves signal integrity. |
Pinout & Package
DS1110S-250+ uses a 16-pin SO (300-mil) surface-mount package with exposed pad not present; lead finish is Pb-free, RoHS-compliant. Pin 1 is VCC, Pin 2 is IN, Pins 3–12 are TAP1 through TAP10 (in order), Pins 13–15 are N.C., and Pin 16 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | 5V supply input; requires local 0.1µF ceramic decoupling adjacent to pin. |
| 2 | IN | Single-ended TTL/CMOS-compatible input; accepts pulses ≥10ns width at 1.5V threshold. |
| 3–12 | TAP1–TAP10 | Fixed-delay outputs (25ns–250ns); each drives 10× 74LS loads directly. |
| 13–15 | N.C. | No internal connection; must remain unconnected; no pull-up/down required. |
| 16 | GND | Digital ground reference; tie to system ground plane with low-inductance path. |
Key Features
| Feature | Design Value |
|---|---|
| 10-Tap Equal Spacing | Guarantees uniform 25ns intervals between taps-critical for linear delay sweep and jitter analysis. |
| Edge-Matched Delay | Identical tPLH and tPHL tolerance ensures zero added duty-cycle distortion on delayed signals. |
| Drop-In DS1010 Replacement | Same pinout and electrical behavior as legacy DS1010, enabling direct board-level upgrade without redesign. |
| Low-Power CMOS Core | Active current ≤150mA at max frequency; reduces thermal load in dense PCB layouts. |
| Automated Assembly Support | SO package qualified for vapor phase, IR, and wave soldering-no reflow profile restrictions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1110E-250+ | 14-pin TSSOP package; identical delay spec, same accuracy, but smaller footprint and higher pin density. | Better suited for space-constrained PCBs; requires different land pattern and stencil design. | Select DS1110E-250+ when board area is limited and TSSOP assembly capability exists. |
| MAX9602ESE+ | 8-tap, 10ns–160ns range, ±3% accuracy, integrated termination; not pin-compatible. | Targeted at high-speed serial data recovery; lacks Tap 9–10 and 250ns capability. | Choose MAX9602ESE+ only for lower-delay, terminated-line applications where 250ns is unnecessary. |
Compared with DS1110E-250+, the DS1110S-250+ offers larger SO package ease-of-handling and legacy layout compatibility; versus MAX9602ESE+, it provides full 10-tap coverage and extended 250ns range essential for industrial timing calibration.

FAQ
What is the exact delay value at Tap 10 for DS1110S-250+?
The DS1110S-250+ delivers a nominal 250ns delay at Tap 10, with tolerance of ±5% or ±2ns (whichever is greater) under 5V and +25°C conditions. This value is factory-trimmed and verified per datasheet Table 1; actual unit-to-unit variation remains within this bound across the full -40°C to +85°C operating range.
Does DS1110S-250+ support both rising- and falling-edge delay matching?
Yes, DS1110S-250+ is explicitly designed for equal precision on both edges: tPLH and tPHL exhibit identical nominal values and matching tolerances (±4ns for delays ≤40ns, ±13% for >40ns). This ensures no duty-cycle distortion is introduced when delaying square-wave or clock-like signals.
Can DS1110S-250+ drive standard TTL loads directly?
Yes, each tap of DS1110S-250+ is rated to drive up to ten 74LS-type loads (IOL = 12mA, IOH = -1.0mA), meeting standard TTL fanout requirements without external buffers. The output structure is CMOS-compatible but robust enough for direct interfacing with legacy TTL logic families.
Is DS1110S-250+ pin-compatible with the older DS1010 delay line?
Yes, DS1110S-250+ is documented as an improved, drop-in replacement for DS1010 in 16-pin SO packaging. Pin assignments, electrical behavior, and timing specifications align fully-enabling direct substitution on existing PCBs without layout changes or firmware updates.
What is the maximum input frequency supported by DS1110S-250+?
DS1110S-250+ supports input periods down to 2×tWI (minimum pulse width), with tWI ≥10ns per datasheet. For reliable operation, input frequencies should remain below 50MHz (20ns period); higher rates risk violating pulse width or period specs and degrading delay accuracy due to layout-dependent coupling effects.
