Product details
Overview
DS1110LE-150+ from Maxim Integrated is a 3V, 10-tap all-silicon delay line delivering precisely spaced 15ns increments (150ns total delay), ±5% or ±2ns accuracy at 3.3V/+25°C, operating from 2.7V to 3.6V, and housed in a 14-pin TSSOP package for timing alignment in high-speed digital systems.
For engineers reviewing the DS1110LE-150+ datasheet, DS1110LE-150+ pinout, DS1110LE-150+ application, or DS1110LE-150+ equivalent, key selection factors include tap spacing consistency, leading/trailing-edge delay matching, industrial temperature range support (-40°C to +85°C), and TTL/CMOS compatibility without external components.
Technical Context
The DS1110LE-150+ implements a monolithic silicon delay architecture with fixed propagation paths-no PLLs, buffers, or programmable logic-ensuring deterministic, voltage- and temperature-stable delays across all 10 taps. Each tap reproduces the input logic state with identical rise/fall edge fidelity.
Delay variation is unidirectional: if Tap 1 slows with temperature, all subsequent taps slow proportionally (per Note 7); tolerance is specified as ±5% or ±2ns (whichever greater) at 3.3V/+25°C, and expands to ±13% for delays >40ns over full -40°C to +85°C range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 150ns nominal; enables precise inter-signal skew correction in synchronous bus interfaces. |
| Tap Spacing | 15ns per tap; supports fine-grained timing adjustment for clock deskewing or pulse shaping. |
| Delay Accuracy | ±5% or ±2ns (greater) at 3.3V/+25°C; guarantees predictable setup/hold margin in production systems. |
| Supply Range | 2.7V to 3.6V; compatible with modern 3V logic families without level-shifting. |
| Operating Temp | -40°C to +85°C; validated for industrial-grade embedded and test equipment deployment. |
| Output Drive | 12mA sink / -1mA source; directly drives 10 × 74LS loads without buffering. |
| Input Capacitance | 5–10pF typical; minimizes signal reflection and loading on high-speed source traces. |
Pinout & Package
DS1110LE-150+ is packaged in a 14-pin TSSOP (173mil body width), 0.65mm pitch, low-profile surface-mount package compliant with IPC/JEDEC J-STD-020A reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended CMOS/TTL-compatible input; accepts 2.2V–3.6V logic-high, -0.3V–0.8V logic-low. |
| 2 | N.C. | No internal connection; must be left floating or tied to GND for mechanical stability. |
| 7 | GND | Dedicated ground reference; requires low-inductance PCB connection to minimize delay jitter. |
| 14 | VCC | Power supply input (2.7V–3.6V); decoupling capacitor (0.1µF) required within 5mm. |
| 3,4,5,6,8,9,10,11,12,13 | TAP1–TAP10 | 10 delay outputs with 15ns spacing; each provides identical rising/falling edge delay relative to IN. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates quartz or LC-based drift; ensures monotonic delay vs. temperature and voltage. |
| Leading- and trailing-edge matching | Enables accurate pulse-width preservation in delay-critical signal conditioning paths. |
| TTL/CMOS compatibility | Direct interface with 74LS, 74HC, and FPGA I/O without level translators or pull-ups. |
| Low-power CMOS operation | Typical ICC = 40–150mA depending on input frequency; suitable for power-constrained ATE. |
| Vapor-phase and IR solderable | Supports standard lead-free reflow processes without reliability degradation. |

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 MC100EP195MNR2G | 10-tap ECL-compatible delay (3.3V supply), ±10% delay tolerance, 16-pin QFN package. | Requires level translation for CMOS systems; higher power (120mA typ), wider temp range (-40°C to +105°C). | Choose when interfacing with ECL or PECL logic; not drop-in for DS1110LE-150+ due to different pinout and drive levels. |
| Analog Devices ADCLK944BCPZ-R7 | 4-output LVDS fanout buffer with programmable delay (0–1.5ns step), not tap-based; 24-pin LFCSP. | Offers fine-grained adjustable delay but no fixed 10-tap structure; requires SPI configuration and external clock. | Prefer for dynamic delay tuning needs; unsuitable as direct replacement for static multi-tap distribution. |
Compared with MC100EP195MNR2G and ADCLK944BCPZ-R7, the DS1110LE-150+ delivers deterministic, zero-configuration 10-tap delay with guaranteed edge-matching and minimal BOM count-ideal for cost-sensitive, high-volume industrial timing applications where fixed latency is required.

FAQ
What is the exact delay value per tap for DS1110LE-150+?
The DS1110LE-150+ provides 10 equally spaced taps with 15ns increments, resulting in a total delay of 150ns from IN to TAP10. Each tap output (TAP1 through TAP10) delivers delays of 15ns, 30ns, 45ns, ..., up to 150ns respectively, as confirmed in Table 1 of the official datasheet and ordering information.
Does DS1110LE-150+ support both rising and falling edge delays with equal accuracy?
Yes, the DS1110LE-150+ produces both leading- and trailing-edge delays with equal precision, as explicitly stated in the General Description and Features sections. Delay tolerance (±5% or ±2ns) applies identically to tPLH and tPHL measurements under the same conditions (3.3V, +25°C).
What is the maximum load each tap of DS1110LE-150+ can drive?
Each tap of the DS1110LE-150+ is rated to drive up to 10 × 74LS-type loads, corresponding to a minimum sink current of 12mA and source current of -1mA at VCC = 2.7V, as specified in the DC Electrical Characteristics table under IOL and IOH parameters.
Is DS1110LE-150+ compatible with 5V logic systems?
No, the DS1110LE-150+ is a 3V-only device with absolute maximum input voltage of +6.0V, but its VIH threshold is defined as 2.2V minimum and VIL as +0.8V maximum-making it incompatible with standard 5V TTL logic levels. It requires 3.3V or 3V logic families (e.g., 74LCX, 74ALVC) for direct interface.
Can DS1110LE-150+ operate outside the -40°C to +85°C range?
No-the DS1110LE-150+ is characterized and guaranteed only over the industrial temperature range of -40°C to +85°C, as stated in the Ordering Information and Absolute Maximum Ratings. Operation outside this range may result in unvalidated delay drift, increased jitter, or functional failure.
