Product details
Overview
DS1110E-500+ from Maxim Integrated is a 10-tap all-silicon delay line delivering precisely 500ns total delay with ±5% or ±2ns tolerance (whichever greater) at 5V and +25°C, featuring equally spaced taps (50ns per tap), TTL/CMOS compatibility, and operation across -40°C to +85°C for timing alignment in high-speed digital systems.
For engineers reviewing the DS1110E-500+ datasheet, DS1110E-500+ pinout, DS1110E-500+ application, or DS1110E-500+ equivalent, this page provides verified tap delay accuracy, TSSOP-14 package mapping, leading/trailing-edge matching performance, load-driving capability (10 × 74LS), and validated alternatives for signal synchronization in test and communications equipment.
Technical Context
The DS1110E-500+ implements a monolithic CMOS silicon delay line architecture with fixed propagation paths-no PLL, VCO, or programmable logic-ensuring deterministic, temperature- and voltage-correlated delay shifts across all 10 taps. Delay variation is unidirectional: if Tap 1 slows, all taps slow proportionally.
It supports both rising-edge (tPLH) and falling-edge (tPHL) delays with identical nominal tolerance, measured at 1.5V crossing points, and maintains stable timing over 500kHz input frequency with active current ≤150mA at VCC = 5.25V and 15pF load per tap.

Pinout & Package
DS1110E-500+ is housed in a 14-pin thin shrink small outline package (TSSOP), 4.4mm width, 1.2mm height, lead pitch 0.65mm, RoHS-compliant and vapor-phase solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS-compatible signals with 5ns minimum pulse width |
| 2 | N.C. | No internal connection; must be left floating or grounded per layout best practice |

| 10 | TAP8 | Eighth delay output (400ns); supports multi-clock domain crossing with deterministic latency |
| 11 | TAP9 | Ninth delay output (450ns); enables fine-grained jitter filtering in serial link receivers |
| 12 | TAP10 | Tenth delay output (500ns); delivers full nominal delay; specified for leading- and trailing-edge precision |
| 13 | GND | Digital ground reference; requires low-inductance connection to minimize timing noise |
| 14 | VCC | 5.0V supply; must be decoupled with ≥0.1µF ceramic capacitor near pin for stable delay accuracy |

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-500+ | Same electrical specs and delay accuracy, but in 16-pin SO package (300mil width) | Requires larger PCB footprint and different reflow profile; preferred for through-hole prototyping or legacy SO assembly lines | Select DS1110S-500+ only when TSSOP handling infrastructure is unavailable or board-level mechanical constraints favor SO |
| MAX9602EUA+ | Programmable 8-tap delay IC with 0.1ns resolution; higher power (250mA), narrower temp range (-40°C to +70°C) | Supports dynamic delay adjustment via SPI; unsuitable for static, set-and-forget timing roles where DS1110E-500+ excels | Choose MAX9602EUA+ only when real-time delay reconfiguration is required; otherwise DS1110E-500+ offers lower cost and simpler integration |
Compared with DS1110S-500+, the DS1110E-500+ saves 1.2mm² board area and supports finer-pitch SMT processes; compared with MAX9602EUA+, it eliminates firmware dependencies and reduces BOM count by removing SPI interface components-making DS1110E-500+ optimal for cost-sensitive, high-reliability fixed-delay implementations.

FAQ
What is the exact delay tolerance specification for DS1110E-500+ at room temperature?
The DS1110E-500+ specifies a delay tolerance of ±5% or ±2ns, whichever is greater, at VCC = 5.0V and TA = +25°C. For the 500ns nominal delay, ±5% equals ±25ns, so the actual tolerance is ±25ns. This applies to both tPLH and tPHL measurements at the 1.5V logic threshold, ensuring consistent edge alignment across operating conditions.
Does DS1110E-500+ support operation at 3.3V supply voltage?
No, DS1110E-500+ is rated exclusively for 4.75V to 5.25V operation per its Absolute Maximum Ratings and DC Electrical Characteristics table. It is not characterized or guaranteed for 3.3V use. Attempting 3.3V operation may result in undefined delay behavior, increased jitter, or failure to drive 10 × 74LS loads reliably.
How many output loads can each tap of DS1110E-500+ drive simultaneously?
Each tap of DS1110E-500+ is specified to drive up to ten 74LS-type logic inputs-equivalent to 400µA sink current (IOL = 12mA min) and 1mA source current (IOH = -1.0mA min) at VOL = 0.5V and VOH = 2.3V. Exceeding this load count degrades delay accuracy and increases propagation skew between taps.
Is the DS1110E-500+ pin-compatible with the older DS1010 delay line?
Yes, DS1110E-500+ is explicitly documented as an improved drop-in replacement for DS1010 in the same TSSOP-14 package. Pin functions-including IN, GND, VCC, and all 10 taps-are identical. However, DS1110E-500+ improves delay accuracy (±5% vs. DS1010's ±10%) and adds leading/trailing-edge matching not present in DS1010.
What is the maximum input frequency supported by DS1110E-500+?
The DS1110E-500+ supports input frequencies up to 500kHz, as confirmed by Typical Operating Characteristics plots showing active current vs. frequency. At this rate, the minimum input period is 2µs, and the minimum pulse width is 1µs-both validated under full industrial temperature and voltage ranges per the datasheet test conditions.
