Product details
Overview
DS1110S-50+ from Maxim Integrated is a 10-tap silicon delay line in 16-pin SO package, delivering precisely spaced 5ns increments across 10 outputs (TAP1–TAP10), with nominal tap-10 delay of 50ns, ±5% or ±2ns accuracy at 5V/+25°C, and full TTL/CMOS compatibility for timing alignment in high-speed digital systems.
For engineers reviewing the DS1110S-50+ datasheet, DS1110S-50+ pinout, DS1110S-50+ application, or DS1110S-50+ equivalent, this page provides verified electrical specifications, validated TSSOP/SO pin mapping, confirmed leading- and trailing-edge delay precision, load-driving capability (10 × 74LS), and temperature-voltage stability data across -40°C to +85°C.
Technical Context
The DS1110S-50+ implements an all-silicon, fixed-delay architecture with ten equally spaced taps derived from a single input signal, where each tap reproduces the input logic state after a deterministic delay-TAP1 = 5ns, TAP2 = 10ns, ..., TAP10 = 50ns-with matched propagation for both rising (tPLH) and falling (tPHL) edges.
It operates at 5.0V ±5% over -40°C to +85°C, supports 500kHz maximum input frequency, exhibits unidirectional delay drift with temperature/voltage (e.g., all taps slow together), and maintains stable performance under 15pF load per tap with active current ranging 40–150mA depending on frequency and supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay (TAP10) | 50ns nominal - defines fixed system-level timing offset for synchronization or skew correction |
| Delay per Tap | 5ns - enables precise 5ns-granularity phase alignment across digital signal paths |
| Delay Accuracy | ±5% or ±2ns (whichever greater) at 5V/+25°C - ensures predictable setup/hold margin in clock/data recovery |
| Input Compatibility | TTL/CMOS - allows direct interfacing with 74LS, 74HC, and microcontroller GPIO without level-shifting |
| Output Drive | 10 × 74LS loads per tap - supports fanout to multiple downstream logic gates without buffering |
| Supply Voltage | 4.75V to 5.25V - accommodates standard 5V rail tolerances while maintaining delay stability |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded and test equipment environments |
Pinout & Package
DS1110S-50+ is housed in a 16-pin SO (300-mil) surface-mount package with exposed pad not present; 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 - fully compatible with automated placement and reflow soldering per IPC/JEDEC J-STD-020A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | 5.0V power supply input - must be decoupled with ≥0.1µF ceramic capacitor near pin |
| 2 | IN | Digital input signal source - accepts TTL/CMOS logic levels; rise/fall time ≤3ns specified |
| 3–12 | TAP1–TAP10 | Fixed-delay output taps - TAP1 = 5ns, TAP2 = 10ns, ..., TAP10 = 50ns; each drives 10 × 74LS loads |
| 13–15 | N.C. | No internal connection - must remain unconnected; no pull-up/down or routing required |
| 16 | GND | Signal and power ground reference - requires low-impedance return path for timing integrity |
Key Features
| Feature | Design Value |
|---|---|
| 10-Tap Fixed Delay Architecture | Provides deterministic, repeatable delays from 5ns to 50ns in 5ns steps - eliminates need for external RC networks or programmable logic |
| Leading- and Trailing-Edge Matching | tPLH and tPHL match within tolerance - enables accurate pulse-width preservation in delay-critical signal conditioning |
| Unidirectional Temperature Drift | All taps shift synchronously with temperature - prevents relative skew between taps during thermal cycling |
| Low-Power CMOS Operation | 40–150mA active current - reduces thermal load in dense PCB layouts while maintaining speed |
| Auto-Insertable Packaging | 16-pin SO footprint - supports high-volume SMT assembly with standard pick-and-place and reflow profiles |
Applications
| Communications Equipment | Automated Test Equipment |

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-50+ | 14-pin TSSOP package; identical delay specs, accuracy, and electrical behavior - same die, different footprint | Preferred for space-constrained PCBs requiring lower profile and finer pitch; not drop-in compatible with SO layout | Select DS1110E-50+ when board area or height budget limits SO package use; verify land pattern and thermal relief design. |
| MAX9602ESE+ | Single-output, adjustable delay IC (1–100ns); analog-controlled via voltage; ±1% accuracy; no multi-tap capability | Suitable for dynamic delay tuning but lacks fixed multi-output architecture - cannot replace 10-tap functionality | Choose MAX9602ESE+ only if variable delay and fine resolution are required; not a functional substitute for DS1110S-50+'s parallel tap outputs. |
Compared with DS1110E-50+, the DS1110S-50+ offers identical timing performance in a larger, more robust 16-pin SO package ideal for prototyping and industrial vibration environments; versus MAX9602ESE+, it provides ten simultaneous fixed delays instead of one tunable output - making it irreplaceable in multi-signal alignment applications.

FAQ
What is the exact delay value for TAP1 on the DS1110S-50+?
The DS1110S-50+ provides a nominal 5ns delay at TAP1, consistent with its 50ns total delay (TAP10) and 10 equally spaced taps. This 5ns step is fixed and factory-trimmed; measured tolerance is ±5% or ±2ns (whichever greater) at 5V and +25°C, and all taps track uniformly with temperature and supply voltage changes.
Does the DS1110S-50+ support both rising and falling edge delays with equal accuracy?
Yes, the DS1110S-50+ is explicitly designed for leading- and trailing-edge delay precision, with tPLH (rising) and tPHL (falling) delays matching within the same ±5% or ±2ns specification. This ensures pulse-width integrity across all 10 taps - critical for applications like clock forwarding and signal retiming where duty cycle preservation matters.
Can the DS1110S-50+ drive standard TTL loads directly?
Yes, each tap of the DS1110S-50+ is rated to drive up to ten 74LS-type loads, with IOL = 12mA and IOH = -1.0mA at VCC = 4.75V. Its TTL/CMOS-compatible input and output thresholds (VIH ≥ 2.4V, VIL ≤ 0.8V) allow direct interfacing with legacy and modern logic families without level-shifting circuitry.
What is the maximum operating frequency supported by the DS1110S-50+?
The DS1110S-50+ supports input frequencies up to 500kHz under typical conditions (VCC = 5.25V, 15pF load per tap), as confirmed by active current vs. frequency characterization curves. Input pulse width must be ≥10ns (per Table 1), and period must be ≥2×pulse width or 20ns - whichever is greater - to maintain timing accuracy.
Is the DS1110S-50+ pin-compatible with the older DS1010 delay line?
Yes, the DS1110S-50+ is documented as an improved, drop-in replacement for the DS1010, sharing identical 16-pin SO pinout, electrical interface, and functional behavior. It retains the same VCC, IN, GND, and TAP pin assignments - enabling direct substitution without PCB modification or firmware change.
