Product details
Overview
DS1110LE-100 from Maxim Integrated is a 3V, 10-tap all-silicon delay line delivering precisely spaced 10ns increments (10–100ns total), ±5% or ±2ns delay accuracy at 3.3V/+25°C, and simultaneous leading- and trailing-edge precision - used in timing alignment for high-speed digital test and communications interfaces.
For engineers reviewing the DS1110LE-100 datasheet, DS1110LE-100 pinout, DS1110LE-100 application, or DS1110LE-100 equivalent, this page delivers verified electrical specs, TSSOP-14 terminal mapping, temperature-voltage stability data, and drop-in alternatives for signal skew correction and pulse shaping in industrial and medical ATE systems.
Technical Context
The DS1110LE-100 implements a monolithic CMOS delay chain with 10 fixed, equally spaced taps - each tap delays the input by exactly 10ns (100ns total), with matched propagation for both rising and falling edges. It operates across 2.7V–3.6V supply and -40°C to +85°C, maintaining ±5% delay tolerance over full range.
Delay variation is unidirectional with temperature/voltage: if Tap 1 slows, all subsequent taps slow proportionally. Input-to-tap delay is measured at 1.5V crossing points, and each output drives up to ten 74LS loads without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 100ns - exact fixed delay from IN to TAP10, enabling precise clock/data phase alignment in synchronous logic. |
| Delay per Tap | 10ns - uniform spacing between consecutive taps (TAP1 = 10ns, TAP2 = 20ns, ..., TAP10 = 100ns). |
| Delay Accuracy | ±5% or ±2ns (whichever greater) at 3.3V/+25°C - guarantees worst-case timing margin for setup/hold validation. |
| Supply Range | 2.7V to 3.6V - compatible with modern 3.3V LVTTL and mixed-voltage system rails. |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded instrumentation and automated test equipment. |
| Output Drive | 12mA sink / -1mA source - sufficient to directly drive 10× 74LS inputs without fanout buffers. |
| Input Capacitance | 5–10pF - low loading preserves signal integrity on high-frequency clock or strobe lines. |
Pinout & Package
DS1110LE-100 is housed in a 14-pin Thin Shrink Small Outline Package (TSSOP), 173mil body width, RoHS-compliant, vapor-phase and IR solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended CMOS/TTL-compatible input; accepts 0–3.3V logic with 5–10pF load. |
| 2 | N.C. | No internal connection; must be left floating or tied to GND for mechanical stability. |
| 7 | GND | Dedicated ground reference for delay chain biasing and noise rejection. |
| 14 | VCC | Primary power supply (2.7–3.6V); decoupling capacitor required within 5mm. |
| 3,4,5,6,8,9,10,11,12,13 | TAP1–TAP10 | 10 buffered delay outputs; TAP1 = 10ns, TAP2 = 20ns, ..., TAP10 = 100ns from IN edge. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates quartz or analog RC drift; ensures monotonic, repeatable delay vs. temperature and voltage. |
| Leading- and trailing-edge matching | Equal tPLH and tPHL tolerances enable accurate pulse-width preservation in delay-critical paths. |
| Unidirectional delay shift | Temperature/voltage changes affect all taps identically - critical for multi-tap skew cancellation. |
| Low-power CMOS operation | 40–150mA active current (frequency-dependent) supports battery-aware or thermally constrained designs. |
| TTL/CMOS compatibility | VIH ≥ 2.2V and VIL ≤ 0.8V allow direct interfacing with legacy 5V logic via level-shifting resistors. |

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 |
|---|---|---|---|
| ON Semiconductor MC100EP195M | 10-tap ECL delay line; 3.3V supply; ±10% accuracy; 16-pin SOIC; higher speed (up to 3GHz input). | Requires negative voltage rail (-3.3V) and level translation for CMOS systems; not TTL-compatible. | Select when ultra-high-frequency edge placement is needed and ECL infrastructure exists. |
| Analog Devices AD9501 | Programmable 8-tap delay IC; 3.3V; ±50ps resolution; SPI-configurable; 24-pin LFCSP. | Software-defined delays replace fixed taps; adds configuration overhead but enables dynamic recalibration. | Select when adaptive delay tuning or field-upgradable timing profiles are required. |
Compared with DS1110LE-100, the MC100EP195M offers higher bandwidth but demands ECL-level signaling, while the AD9501 provides programmability at the cost of added interface complexity and reduced tap count - DS1110LE-100 remains optimal for simple, low-jitter, fixed-delay insertion in cost-sensitive industrial designs.

FAQ
What is the nominal delay accuracy of DS1110LE-100 at room temperature?
The DS1110LE-100 guarantees ±5% or ±2ns delay accuracy - whichever is greater - at 3.3V and +25°C. For its 100ns total delay, this translates to a ±5ns maximum deviation. This specification applies to both leading- and trailing-edge delays, ensuring symmetrical timing behavior critical for pulse-width integrity.
Can DS1110LE-100 operate from a 2.5V supply?
No - DS1110LE-100 is characterized for 2.7V to 3.6V operation only. At 2.5V, timing parameters including delay accuracy, output drive strength, and input threshold levels fall outside datasheet specifications. Operation below 2.7V may result in increased delay variation or functional failure.
How many output loads can each tap of DS1110LE-100 drive?
Each tap of DS1110LE-100 is rated to drive up to ten 74LS-type loads (equivalent to ~400Ω || 15pF). This is confirmed under AC conditions with 15pF capacitive loading per tap and meets VOL ≤ 0.5V at IOL = 12mA and VOH ≥ 2.3V at IOH = -1mA.
Is DS1110LE-100 pin-compatible with other DS1110L variants like DS1110LE-200?
Yes - all DS1110LE-x variants share identical 14-pin TSSOP packaging, pinout, and electrical interface. Only the total delay (and thus tap spacing) differs: DS1110LE-100 provides 10ns/tap, while DS1110LE-200 provides 20ns/tap. No PCB changes are required when substituting within the same package variant.
Does DS1110LE-100 require external termination or impedance matching?
No external termination is required for standard operation. The DS1110LE-100 outputs are designed for CMOS/TTL loads and specify performance with 15pF capacitance per tap. For transmission-line routing (>10cm traces), series 33Ω source termination is recommended to suppress reflections - but this is a board-layout consideration, not a device requirement.
