Product details
Overview
DS1110E-75+ from Maxim Integrated is a 10-tap silicon delay line in 14-pin TSSOP, delivering precisely spaced 7.5ns increments (total 75ns) with ±5% or ±2ns accuracy at 5V/+25°C. It reproduces input logic state at Tap 10 after fixed delay, supports both leading- and trailing-edge timing, and drives up to ten 74LS loads - used in high-speed digital synchronization for ATE and medical timing circuits.
For engineers reviewing the DS1110E-75+ datasheet, DS1110E-75+ pinout, DS1110E-75+ application, or DS1110E-75+ equivalent, key selection criteria include tap spacing tolerance, edge-matched delay stability across temperature/voltage, TTL/CMOS compatibility, and TSSOP footprint suitability for dense PCB layouts in industrial-grade timing systems.
Technical Context
The DS1110E-75+ implements an all-silicon CMOS delay architecture with ten equally spaced taps derived from a single propagation path. Each tap provides deterministic delay relative to the input (IN), with identical tPLH/tPHL characteristics for rising and falling edges.
Delay accuracy is specified as ±5% or ±2ns (whichever greater) at 5V/+25°C, and maintains unidirectional drift with temperature or supply variation - if Tap 1 slows, all taps slow proportionally. It operates over -40°C to +85°C with 4.75V–5.25V supply and supports 500kHz maximum input frequency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 75ns nominal at Tap 10 - defines fixed system-level timing offset for clock/data alignment |
| Delay per Tap | 7.5ns - enables precise sub-cycle phase stepping in digital signal conditioning |
| Delay Accuracy | ±5% or ±2ns (greater) at 5V/+25°C - sets worst-case timing margin for setup/hold validation |
| Operating Temp | -40°C to +85°C - supports industrial and medical equipment deployment without derating |
| Supply Voltage | 4.75V to 5.25V - compatible with standard 5V logic rails and tolerant of typical board-level ripple |
| Output Drive | 12mA sink / -1mA source - sufficient to fan-out to ten 74LS inputs without buffering |
| Input Capacitance | 5–10pF - minimizes loading on upstream drivers and preserves signal integrity at high frequencies |
Pinout & Package
DS1110E-75+ uses a 14-pin thin-shrink small-outline package (TSSOP), optimized for automated assembly and space-constrained industrial PCBs. Pin 1 is IN; Pins 2 and 3 are no-connect; Pin 7 is GND; Pin 14 is VCC; remaining pins (4–6, 8–13) correspond to TAP1 through TAP10 in sequence.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Primary logic input - accepts TTL/CMOS-compatible signals; referenced to GND |
| 2, 3 | N.C. | No internal connection - must remain unconnected to avoid parasitic coupling |
| 4–6, 8–13 | TAP1–TAP10 | Fixed-delay outputs - each delivers delayed copy of IN with 7.5ns step increment |
| 7 | GND | Digital ground reference - requires low-impedance return path for timing stability |
| 14 | VCC | +5V supply - bypassing with 0.1µF ceramic capacitor near pin is mandatory for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| 10-Tap Equal Spacing | 7.5ns intervals enable fine-grained delay tuning without interpolation or external circuitry |
| Leading- & Trailing-Edge Match | Identical tPLH/tPHL ensures symmetrical pulse shaping - critical for duty-cycle preservation |
| ±5% Delay Tolerance | Guarantees predictable timing window across production lots and operating conditions |
| TTL/CMOS Compatibility | Accepts standard logic thresholds (VIH ≥ 2.4V, VIL ≤ 0.8V) - eliminates level-shifting needs |
| 14-Pin TSSOP Footprint | 0.65mm pitch, 5mm × 4.4mm body - supports high-density routing and reflow soldering |
Applications
| Automated Test Equipment (ATE) | Medical Imaging Timing Control |

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 |
|---|---|---|---|
| DS1110S-75+ | Same electrical specs and delay performance, but in 16-pin SO package (300mil width) | Requires larger PCB area and different thermal profile during reflow; less suitable for high-density layouts | Select DS1110S-75+ only when SO package compatibility or legacy board reuse is required |
| MAX9600EUA+ | Single-output 75ns delay, no tap structure; ±1.5% accuracy; 8-pin µMAX package | Lacks multi-tap flexibility - usable only where one fixed delay is needed, not phased outputs | Choose MAX9600EUA+ for minimal footprint and tighter accuracy when tap diversity is unnecessary |
Compared with DS1110S-75+, the DS1110E-75+ saves 35% board area and supports finer layout control; versus MAX9600EUA+, it trades single-output precision for ten independently accessible delay points essential for multi-phase timing architectures.

FAQ
What is the exact delay value at Tap 10 for DS1110E-75+?
The DS1110E-75+ delivers a nominal 75ns delay at Tap 10, with tolerance of ±5% or ±2ns (whichever is greater) under 5V/+25°C conditions. This value is factory-trimmed and verified per datasheet Table 1; actual unit-to-unit variation remains within this spec across the full -40°C to +85°C operating range.
Does DS1110E-75+ support both rising and falling edge delays equally?
Yes, DS1110E-75+ is explicitly designed for equal leading- and trailing-edge precision. Its tPLH and tPHL parameters are matched within tolerance - confirmed in the AC Electrical Characteristics table and Figure 2 timing diagram - ensuring symmetrical pulse delay critical for duty-cycle-sensitive applications.
Can DS1110E-75+ drive standard TTL loads directly?
Yes, DS1110E-75+ can drive up to ten 74LS-type loads per tap, as specified in the Detailed Description and DC Electrical Characteristics. Its IOL = 12mA and IOH = -1mA ratings meet 74LS input current requirements without external buffers, simplifying interface design in legacy logic systems.
What is the recommended power supply decoupling for DS1110E-75+?
A 0.1µF ceramic capacitor placed as close as possible to the VCC (Pin 14) and GND (Pin 7) pins is mandatory for DS1110E-75+. This minimizes supply-induced jitter and ensures stable delay performance, especially under fast-switching load conditions - per layout guidance in the datasheet's Test Conditions section.
Is DS1110E-75+ pin-compatible with DS1010 series devices?
No, DS1110E-75+ is not pin-compatible with DS1010. While it is an improved functional replacement, DS1110E-75+ uses a 14-pin TSSOP with different pin mapping (e.g., N.C. on Pins 2–3, Tap outputs on Pins 4–6/8–13), whereas DS1010 uses older 16-pin packages with distinct pinout - PCB redesign is required for migration.
