Product details
Overview
DS1110S-300 from Maxim Integrated is a 10-tap silicon delay line in 16-pin SO package, delivering precisely spaced 30ns increments across ten outputs (TAP1–TAP10), with total tap-10 delay of 300ns, ±5% or ±2ns accuracy at 5V/+25°C, and TTL/CMOS compatibility for timing alignment in high-speed digital systems.
For engineers reviewing the DS1110S-300 datasheet, DS1110S-300 pinout, DS1110S-300 application, or DS1110S-300 equivalent, this page provides verified delay tolerance, tap-specific drive capability (10 × 74LS loads), temperature-voltage stability data, and validated drop-in alternatives for communications, test equipment, and medical timing circuits.
Technical Context
The DS1110S-300 implements an all-silicon, fixed-delay architecture with unidirectional delay variation - all taps slow or speed together under voltage or temperature shifts. It supports both leading- and trailing-edge delays measured at 1.5V thresholds with identical precision.
Each tap output drives up to ten 74LS loads without external buffering; active current ranges from 40mA to 150mA depending on input frequency and supply voltage, with power-up time limited to 200ms. Delay specification applies across -40°C to +85°C industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay (TAP10) | 300ns nominal; enables precise clock/data phase alignment in serial interfaces and sampling systems |
| Delay per Tap | 30ns; provides uniform 30ns step resolution for multi-stage timing control |
| Delay Accuracy | ±5% or ±2ns (whichever greater) at 5V/+25°C; ensures predictable setup/hold margin in synchronous logic |
| Operating Voltage | 4.75V to 5.25V; compatible with standard 5V TTL/CMOS logic rails without level shifting |
| Temperature Range | -40°C to +85°C; supports industrial-grade operation in ATE and medical equipment |
| Output Drive | 12mA sink / -1mA source per tap; sufficient to directly drive 10 × 74LS inputs without fanout buffers |
| Input Pulse Width | ≥10ns minimum; accommodates fast edges in high-frequency digital signal conditioning |
Pinout & Package
DS1110S-300 is housed in a 16-pin SOIC (300-mil width) package with exposed pad not present; pin assignments are fully defined in Maxim's official pin configuration diagram.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | 5.0V supply input; requires local 0.1µF bypass capacitor to GND for stable delay performance |
| 2, 3, 15 | N.C. | No internal connection; must remain unconnected to avoid parasitic coupling or latch-up risk |
| 4–14 | TAP1–TAP10 | Delay outputs with 30ns spacing; TAP1 = 30ns, TAP10 = 300ns; all outputs TTL/CMOS compatible |
| 8 | IN | Digital input accepting 0.8V/2.4V logic thresholds; rise/fall times ≤3ns required for spec-compliant delay |
| 16 | GND | Ground reference for all I/O and internal delay circuitry; must be low-impedance plane for jitter control |
Key Features
| Feature | Design Value |
|---|---|
| 10-Tap Fixed Delay Architecture | Provides deterministic, repeatable propagation delays without PLL lock time or configuration overhead |
| Leading- and Trailing-Edge Matching | Ensures symmetrical delay for both signal edges - critical for pulse-width preservation in timing-critical paths |
| Drop-In Replacement for DS1010 | Same pinout and electrical behavior as legacy DS1010, enabling direct upgrade without PCB revision |
| Low-Power CMOS Operation | Active current 40–150mA range minimizes thermal load in dense timing subsystems |
| Auto-Insertable Packaging | 16-pin SOIC footprint supports standard SMT assembly processes including vapor-phase and wave soldering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1110E-300 | 14-pin TSSOP package; identical delay specs, same ±5%/±2ns accuracy, but smaller footprint and higher thermal resistance | Preferred for space-constrained PCBs where thermal management allows; not interchangeable due to different pin count and layout | Select DS1110E-300 only when board area is constrained and thermal derating is acceptable. |
| MAX9600EUA+ | Programmable 8-tap delay IC with SPI interface; 1ns resolution, ±100ps accuracy, but requires configuration and consumes more power | Suitable for adaptive delay calibration systems; not drop-in due to active control requirements and different pinout | Choose MAX9600EUA+ only when dynamic delay adjustment or sub-ns precision is required. |
Compared with DS1110E-300, the DS1110S-300 offers better thermal dissipation and mechanical robustness in SOIC packaging, while compared with MAX9600EUA+, it delivers zero-configuration, ultra-low-jitter fixed delay at lower system-level complexity and cost.

FAQ
What is the exact delay value at TAP1 for DS1110S-300?
The DS1110S-300 provides 30ns delay at TAP1, with subsequent taps incrementing by 30ns each (TAP2 = 60ns, ..., TAP10 = 300ns). This 30ns/tap spacing is factory-trimmed and specified over -40°C to +85°C, maintaining ±5% or ±2ns accuracy at 5V/+25°C. The DS1110S-300 achieves this via all-silicon delay elements with matched process characteristics.
Does DS1110S-300 support both rising and falling edge delays with equal accuracy?
Yes, the DS1110S-300 is explicitly designed for leading- and trailing-edge delay matching, measuring tPLH and tPHL at the 1.5V threshold with identical tolerance (±5% or ±2ns). This symmetry ensures pulse-width integrity across all ten taps, making DS1110S-300 suitable for applications like clock deskewing where duty cycle preservation is critical.
Can DS1110S-300 drive standard TTL loads directly?
Yes, each tap of the DS1110S-300 can drive up to ten 74LS-type loads (12mA sink, -1mA source), meeting standard TTL interface requirements without external buffers. This capability is verified across the full -40°C to +85°C operating range and eliminates fanout logic in timing distribution networks using DS1110S-300.
Is DS1110S-300 pin-compatible with the older DS1010 series?
Yes, the DS1110S-300 is an improved drop-in replacement for DS1010, sharing identical 16-pin SOIC pinout, voltage levels, and functional behavior. No PCB changes are needed when upgrading from DS1010 to DS1110S-300, and the DS1110S-300 improves upon DS1010 with tighter delay tolerance and enhanced edge-matching performance.
What is the maximum input frequency supported by DS1110S-300?
The DS1110S-300 supports input periods as short as 2×tWI (minimum pulse width), with tWI ≥10ns per datasheet specifications. This corresponds to a maximum fundamental input frequency of approximately 50MHz for square-wave operation. Performance remains stable up to this rate, with DS1110S-300 active current scaling predictably from 40mA to 150mA across that range.
