Product details
Overview
DS1110E-50+ from Maxim Integrated is a 10-tap silicon delay line in 14-pin TSSOP, delivering precisely spaced 5ns increments across 50ns total delay (tap 10 = 50ns), ±5% or ±2ns accuracy at 5V/+25°C, TTL/CMOS-compatible outputs capable of driving ten 74LS loads, and simultaneous leading- and trailing-edge delay precision for digital timing alignment in high-speed logic systems.
For engineers reviewing the DS1110E-50+ datasheet, DS1110E-50+ pinout, DS1110E-50+ application, or DS1110E-50+ equivalent, this page provides verified tap delay values, temperature/voltage stability data, TSSOP terminal mapping, and functionally comparable alternatives for signal skew correction, clock deskewing, and pulse width adjustment in industrial and test equipment.
Technical Context
The DS1110E-50+ implements an all-silicon, low-power CMOS delay architecture with fixed propagation paths per tap-no PLL or programmable logic involved. Each of its ten taps provides deterministic, monotonic delay progression (5ns/tap), with identical tPLH and tPHL tolerances across -40°C to +85°C.
Delay stability relies on matched internal transistor sizing and voltage-regulated biasing-not external components. Input-to-tap timing is referenced to 1.5V crossing points, and all taps track unidirectionally with temperature or supply variation, ensuring consistent inter-tap spacing under operating stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay (Tap 10) | 50 ns - fixed, factory-trimmed delay from IN to TAP10 output |
| Delay per Tap | 5 ns - equally spaced intervals enabling precise sub-cycle timing adjustments |
| Delay Accuracy | ±5% or ±2 ns (whichever greater) at 5V/+25°C - defines worst-case skew budget for timing-critical paths |
| Operating Voltage | 4.75 V to 5.25 V - compatible with standard 5V TTL/CMOS logic rails without level shifting |
| Temperature Range | -40°C to +85°C - qualified for industrial-grade embedded and ATE environments |

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 |
|---|---|---|---|
| DS1010S-50+ | Legacy 10-tap delay line; ±10% accuracy; no TSSOP option; higher ICC (200mA typ) | Limited to commercial temp range (-20°C to +70°C); not qualified for industrial ATE use | Select only if legacy board reuse mandates DS1010 footprint compatibility and ±10% tolerance is acceptable |
| MAX9602EUA+ | 8-tap, 100ps resolution, ±100ps accuracy; 3.3V operation; SPI-configurable | Requires microcontroller interface; unsuitable for glueless, static-delay applications | Choose when programmable delay resolution and 3.3V compatibility outweigh fixed-tap simplicity |
Compared with DS1010S-50+, DS1110E-50+ improves delay accuracy by 2× and extends temperature range to -40°C to +85°C; compared with MAX9602EUA+, it eliminates configuration overhead and supports direct 5V TTL interfacing but lacks fine-grained adjustability.

FAQ
What is the exact delay value at TAP10 for DS1110E-50+?
The DS1110E-50+ delivers a nominal 50 ns delay from the IN pin to the TAP10 output, measured at the 1.5V crossing point for both rising and falling edges. This value is factory-trimmed and specified with ±5% or ±2 ns tolerance (whichever is greater) at 5V and +25°C. The DS1110E-50+ datasheet confirms this as the total delay for the full 10-tap chain.
Does DS1110E-50+ support both rising and falling edge delays with equal precision?
Yes, the DS1110E-50+ is explicitly designed to provide matching leading-edge (tPLH) and trailing-edge (tPHL) delay accuracy across all ten taps. The datasheet states "designed to produce both leading- and trailing-edge delays with equal precision," and AC specifications confirm identical min/max tolerances for both parameters under all operating conditions.
Can DS1110E-50+ drive standard TTL loads directly?
Yes, each tap of the DS1110E-50+ can drive up to ten 74LS-type loads without external buffering. Its IOL is rated at 12 mA (min) and IOH at -1 mA (min) at VCC = 4.75 V, satisfying the DC interface requirements of legacy TTL families. This capability is confirmed in the "Detailed Description" and "DC Electrical Characteristics" sections of the official datasheet.
What is the recommended bypass capacitor for DS1110E-50+?
A 0.1 µF ceramic capacitor is required between VCC (pin 14) and GND (pin 7) for DS1110E-50+, placed within 5 mm of the device. This is specified in the "Pin Description" and "Typical Operating Characteristics" sections to suppress high-frequency noise and maintain delay stability under fast-switching loads.
Is DS1110E-50+ pin-compatible with DS1110S-50+?
No, DS1110E-50+ (14-pin TSSOP) and DS1110S-50+ (16-pin SO) have different pin counts, layouts, and pin functions-including two extra N.C. pins in the SO variant. They share identical electrical behavior and delay specifications but require separate PCB footprints and cannot be substituted without layout modification.
