Product details
Overview
DS1110LE-50+ from Maxim Integrated is a 3V, 10-tap all-silicon delay line delivering precisely spaced 50ns increments (total 500ns delay), ±5% or ±2ns accuracy at 3.3V/+25°C, TTL/CMOS-compatible input/output, and operation from -40°C to +85°C in a 14-pin TSSOP package - used for timing alignment in high-speed digital test and medical pulse synchronization.
For engineers reviewing the DS1110LE-50+ datasheet, DS1110LE-50+ pinout, DS1110LE-50+ application, or DS1110LE-50+ equivalent, key selection factors include tap spacing tolerance, leading/trailing-edge delay matching, supply voltage range (2.7V–3.6V), output drive capability (10 × 74LS loads), and industrial temperature qualification.
Technical Context
The DS1110LE-50+ implements a monolithic silicon delay chain with 10 fixed-output taps, each offset by exactly 50ns (500ns total), with matched propagation for both rising and falling edges. Delay stability is maintained across voltage (2.7V–3.6V) and temperature (-40°C to +85°C) via process-compensated CMOS design.
All taps reproduce logic state with identical edge fidelity; no internal clock or control logic is required - it operates as a passive, deterministic analog delay path. Input pulse width minimum is 10ns, and output loading is specified at 15pF + 450Ω per tap.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 500ns - fixed end-to-end propagation time from IN to TAP10, enabling precise system-level timing budgeting |
| Tap Spacing | 50ns - uniform 10-step delay resolution supports incremental signal alignment in ATE and serial data recovery |
| Delay Accuracy | ±5% or ±2ns (whichever greater) at 3.3V/+25°C - guarantees worst-case timing margin for synchronous sampling circuits |
| Supply Range | 2.7V to 3.6V - compatible with modern 3.3V logic domains and tolerant of rail droop in dense PCB layouts |
| Operating Temp | -40°C to +85°C - qualified for industrial and medical equipment without derating or thermal management |
| Output Drive | 12mA sink / 1mA source - sufficient to directly interface with 74LS-family inputs without buffering |
| Input Capacitance | 5–10pF - low capacitive loading preserves signal integrity on high-speed clock or strobe lines |
Pinout & Package
DS1110LE-50+ is housed in a 14-pin Thin Shrink Small Outline Package (TSSOP), 173mil body width, 0.65mm lead pitch, JEDEC MO-153 compliant, vapor-phase and IR solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended TTL/CMOS-compatible input; accepts pulses ≥10ns wide, referenced to GND |
| 2 | N.C. | No internal connection; must be left unconnected or grounded per layout best practice |
| 7 | GND | Dedicated ground reference for delay chain bias and output termination |
| 14 | VCC | Primary power supply (2.7V–3.6V); requires local 0.1µF ceramic decoupling |
| 3,4,5,6,8,9,10,11,12,13 | TAP1–TAP10 | Fixed-delay outputs: TAP1 = 50ns, TAP2 = 100ns, ..., TAP10 = 500ns; each drives 10 × 74LS loads |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates external RC networks or quartz-based solutions, ensuring long-term aging stability and shock resistance |
| Leading- and trailing-edge matched delay | Enables accurate pulse-width preservation in delay-sensitive applications like laser trigger gating and ADC sampling windows |
| ±5% or ±2ns delay tolerance | Provides predictable worst-case skew for multi-tap fanout in high-reliability test instrumentation |
| Low-power CMOS operation | Draws ≤150mA active current at max frequency, reducing thermal load in densely packed ATE backplanes |
| TTL/CMOS input compatibility | Accepts standard logic thresholds without level-shifting, simplifying integration into mixed-voltage systems |
Applications
| Automated Test Equipment (ATE) | Medical Imaging Pulse Control |

Use Value: Delivers stable 50ns increments across voltage variation (2.7V–3.6V), eliminating need for recalibration during brown-out events. |
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 |
|---|---|---|---|
| DS1023S-50+ (Maxim) | 8-tap, 50ns spacing, 400ns max delay; same 14-pin TSSOP but fewer taps and lower max delay | Limited to shorter timing budgets; lacks TAP9/TAP10 needed for full 500ns alignment | Select when system requires only up to 400ns delay and board space is constrained |
| ICS8302AM-01LFT (Renesas) | 10-tap, 50ns spacing, but requires external clock; not true all-silicon delay - uses PLL-based architecture | Introduces jitter and lock-time uncertainty; unsuitable for single-shot or asynchronous pulse delay | Choose only if programmable delay range or frequency synthesis is required alongside fixed taps |
Compared with DS1110LE-50+, DS1023S-50+ offers identical tap resolution but reduced depth, while ICS8302AM-01LFT trades deterministic analog delay for programmability at the cost of added jitter and startup latency - making DS1110LE-50+ optimal for static, low-jitter, single-event timing tasks.

FAQ
What is the exact delay value for each tap on the DS1110LE-50+?
Each tap on the DS1110LE-50+ provides a fixed, cumulative delay: TAP1 = 50ns, TAP2 = 100ns, TAP3 = 150ns, TAP4 = 200ns, TAP5 = 250ns, TAP6 = 300ns, TAP7 = 350ns, TAP8 = 400ns, TAP9 = 450ns, and TAP10 = 500ns. These values are specified at 3.3V and +25°C with ±5% or ±2ns tolerance, whichever is greater, and remain equally spaced across the full operating temperature and voltage range.
Does the DS1110LE-50+ support both rising and falling edge delays with equal accuracy?
Yes, the DS1110LE-50+ produces matched leading-edge (tPLH) and trailing-edge (tPHL) delays across all 10 taps, with identical tolerance specifications. This ensures pulse-width integrity is preserved - critical for applications such as laser diode gating or ADC sample window control where duty cycle fidelity matters.
Can the DS1110LE-50+ operate from a 2.5V supply?
No, the DS1110LE-50+ is characterized and guaranteed only from 2.7V to 3.6V. Operation below 2.7V is outside specification and may result in increased delay variation, reduced output drive strength, or failure to meet the ±5%/±2ns accuracy guarantee. For 2.5V systems, consider redesigning the power domain or selecting a different delay solution.
What is the maximum input frequency supported by the DS1110LE-50+?
The DS1110LE-50+ does not specify a maximum input frequency, but its minimum input pulse width is 10ns (per AC Electrical Characteristics). Therefore, the practical upper limit is ~50MHz for 50% duty-cycle signals. Performance remains stable up to this rate, with active current rising predictably (e.g., ~10mA at 25MHz with 15pF load per tap).
Is the DS1110LE-50+ pin-compatible with other DS1110L variants like DS1110LE-250+?
Yes, all DS1110L variants including DS1110LE-50+ share identical 14-pin TSSOP packaging and pinout - only the total delay (and thus tap spacing) differs. This allows direct substitution in existing layouts when adjusting timing budgets, provided system-level delay requirements align with the new tap spacing (e.g., 25ns vs. 50ns).
