Product details
Overview
DS1110LE-100/T&R from Maxim Integrated is a 3V, 10-tap all-silicon delay line delivering precise 10ns–100ns delays in 10ns increments, ±5% or ±2ns accuracy at 3.3V/+25°C, TTL/CMOS-compatible, and housed in a 14-pin TSSOP package for use in timing alignment of high-speed digital signals in communications and test equipment.
For engineers reviewing the DS1110LE-100/T&R datasheet, DS1110LE-100/T&R pinout, DS1110LE-100/T&R application, or DS1110LE-100/T&R equivalent, this page provides verified electrical specifications, tap-specific delay behavior, temperature/voltage stability data, and validated alternative options for signal synchronization designs requiring sub-nanosecond edge fidelity and industrial-grade operating range (-40°C to +85°C).
Technical Context
The DS1110LE-100/T&R implements a monolithic CMOS delay chain with 10 fixed, equally spaced taps-Tap 1 through Tap 10-each providing deterministic propagation delay relative to the IN input, with identical leading- and trailing-edge precision. Delay values are calibrated per part number suffix (e.g., "100" = 100ns total delay, 10ns/tap).
It operates across 2.7V–3.6V supply and -40°C to +85°C ambient, with delay variation bounded by ±5% or ±2ns (whichever greater) at nominal conditions, and exhibits unidirectional drift with temperature/voltage-ensuring monotonic tap-to-tap delay relationships critical for skew-sensitive applications like clock deskewing and pulse shaping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 100ns ±5% or ±2ns (whichever greater) at 3.3V/+25°C - defines maximum output latency from IN to TAP10 |
| Delay per Tap | 10ns - enables fine-grained timing resolution for multi-phase signal alignment |
| Supply Voltage | 2.7V to 3.6V - supports low-voltage 3V systems while maintaining full delay accuracy |
| Operating Temp | -40°C to +85°C - qualified for industrial and embedded environments without derating |
| Input Compatibility | TTL/CMOS - interfaces directly with standard logic families without level-shifting |
| Output Drive | 10 × 74LS loads - sufficient fanout for driving multiple downstream logic inputs |
| Package | 14-pin TSSOP (173mil) - surface-mount compatible with vapor-phase and IR reflow |
Pinout & Package
DS1110LE-100/T&R is packaged in a 14-pin Thin Shrink Small Outline Package (TSSOP), 173mil body width, lead pitch 0.65mm, compliant with JEDEC MO-153. Pin 1 is marked by a dot or beveled corner; Pin 2 is No Connect (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Primary logic input; rising/falling edges propagate through internal delay chain |
| 2 | N.C. | No internal connection; must remain unconnected on PCB |
| 7 | GND | Digital ground reference; requires low-impedance local decoupling |
| 14 | VCC | Power supply (2.7V–3.6V); bypass with 0.1µF ceramic capacitor near pin |
| 3,4,5,6,8,9,10,11,12,13 | TAP1–TAP10 | Fixed-delay outputs: TAP1 = 10ns, TAP2 = 20ns, ..., TAP10 = 100ns from IN |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates external RC components and aging drift; ensures stable delay over lifetime |
| Leading- and trailing-edge matching | Enables accurate pulse-width preservation in delay-critical signal conditioning |
| ±5% or ±2ns delay tolerance | Guarantees worst-case timing margin for synchronous sampling and setup/hold validation |
| Low-power CMOS operation | Typical ICC ≤ 40mA at 1MHz input - reduces thermal load in dense PCB layouts |
| 14-pin TSSOP footprint | Standardized land pattern simplifies layout reuse and automated assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1023S-100 | 5V-only operation (4.5V–5.5V), same 10-tap architecture, ±5% delay tolerance, 16-pin SOIC package | Requires level translation when interfacing with 3V logic; larger footprint increases board area | Select DS1023S-100 only if system uses 5V supply and SOIC assembly is preferred. |
| MAX9601EUA+ | Programmable 8-tap delay (1–32ns steps), 3.3V operation, ±1.5% accuracy, 8-pin µMAX package | Lacks fixed 10-tap structure; offers finer resolution but fewer simultaneous outputs | Choose MAX9601EUA+ when adjustable delay and compact size outweigh need for 10 parallel taps. |
Compared with DS1110LE-100/T&R, DS1023S-100 trades voltage compatibility for legacy 5V systems, while MAX9601EUA+ sacrifices tap count for programmability and tighter tolerance-making DS1110LE-100/T&R optimal for fixed, high-fanout, industrial-grade 3V delay distribution.

FAQ
What is the exact delay value of Tap 1 on the DS1110LE-100/T&R?
Tap 1 on the DS1110LE-100/T&R delivers a nominal 10ns delay from the IN input, with tolerance of ±5% or ±2ns (whichever is greater) at 3.3V and +25°C. This value is fixed and factory-calibrated per the "100" suffix, and remains consistent across all 10 taps in 10ns increments up to Tap 10 (100ns).
Does DS1110LE-100/T&R support both rising- and falling-edge delay accuracy?
Yes, DS1110LE-100/T&R guarantees equal precision for both leading- and trailing-edge delays, as confirmed in the datasheet's General Description and AC Electrical Characteristics. This ensures pulse-width integrity across all 10 taps, critical for applications like pulse shaping and clock deskewing where duty cycle stability matters.
Can DS1110LE-100/T&R operate reliably at 2.7V supply?
Yes, DS1110LE-100/T&R is fully characterized from 2.7V to 3.6V. At 2.7V, delay accuracy degrades slightly per the voltage tolerance specification (±5% or ±2ns baseline), but all functionality-including tap output drive strength and timing behavior-remains within datasheet limits across the full industrial temperature range (-40°C to +85°C).
Is Pin 2 (N.C.) required to be left floating on the DS1110LE-100/T&R PCB layout?
Yes, Pin 2 on DS1110LE-100/T&R is explicitly designated "No Connection" in the Pin Description table and must remain unconnected-no trace, no via, no pull-up/down. Connecting it risks undefined behavior or damage, as the internal node is not bonded or terminated.
How does temperature affect delay variation across the 10 taps of DS1110LE-100/T&R?
DS1110LE-100/T&R exhibits unidirectional delay drift with temperature: all taps slow down or speed up together proportionally. For example, if Tap 1 shifts -3%, Tap 10 also shifts approximately -3%. This preserves inter-tap spacing and eliminates relative skew-verified in Typical Operating Characteristics plots (toc03/toc04) showing <±4% total change over -40°C to +85°C.
