Product details
Overview
DS1100U-500+ from Maxim Integrated is a 5-tap silicon delay line delivering precise, fixed delays of 100ns, 200ns, 300ns, 400ns, and 500ns across its taps. It operates at 5V, reproduces both leading and trailing edges with equal accuracy, and drives up to 10 LS-TTL loads per tap-used in digital timing alignment, pulse shaping, and clock skew compensation in industrial control and test equipment.
For engineers reviewing the DS1100U-500+ datasheet, DS1100U-500+ pinout, DS1100U-500+ application, or DS1100U-500+ equivalent, key selection considerations include tap delay tolerance (±13% over -40°C to +85°C), 5V CMOS/TTL compatibility, µMAX-8 package footprint, low-power operation (30–50mA ICC), and edge-fidelity critical for synchronous logic interfacing.
Technical Context
The DS1100U-500+ implements an all-silicon delay architecture with five equally spaced, fixed-delay outputs referenced to a single input signal. Each tap provides deterministic propagation delay without external components or configuration registers.
It supports full industrial temperature range (-40°C to +85°C) with delay stability specified as ±13% for delays >40ns, and maintains consistent unidirectional drift across all taps under voltage or temperature variation-ensuring monotonic timing relationships between outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | 100ns / 200ns / 300ns / 400ns / 500ns - fixed, factory-trimmed delays enabling precise multi-stage timing alignment |
| Supply Voltage | 4.75V to 5.25V - compatible with standard 5V logic rails and tolerant of typical power rail ripple |
| Delay Tolerance | ±13% over -40°C to +85°C - ensures predictable timing margin in harsh environments |
| Input/Output Compatibility | TTL/CMOS - interfaces directly with 74LS, 74F, and modern 5V logic families without level shifting |
| Load Drive Capability | 10 × 74LS loads per tap - sufficient fanout for distributed timing distribution without buffers |
| Power Consumption | 30–50mA active current at 1MHz - enables low-heat, space-constrained PCB placement |
| Edge Accuracy | Equal leading- and trailing-edge delay precision - preserves pulse width integrity in delay-critical applications |
Pinout & Package
DS1100U-500+ is housed in an 8-pin µMAX® package (U8+1 outline), measuring 3mm × 3mm with 0.65mm pitch, optimized for high-density surface-mount layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | +5V supply input - must be decoupled locally to maintain delay stability under fast switching |
| 2 | TAP 1 | First delayed output (100ns) - used for shortest-path timing correction or reference delay stage |
| 3 | TAP 3 | Third delayed output (300ns) - central tap for mid-range alignment or differential delay generation |
| 4 | TAP 5 | Fifth delayed output (500ns) - longest fixed delay for maximum skew compensation or pipeline staging |
| 5 | IN | Digital input signal - accepts TTL/CMOS logic levels; rise/fall time ≤3ns required for spec-compliant delay accuracy |
| 6 | TAP 2 | Second delayed output (200ns) - provides intermediate step between TAP1 and TAP3 for fine-grained timing control |
| 7 | TAP 4 | Fourth delayed output (400ns) - bridges gap between TAP3 and TAP5 for cascaded or staggered delay chains |
| 8 | GND | Ground reference - requires low-inductance connection to minimize ground bounce-induced jitter |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay core | Eliminates hybrid or ceramic delay line reliability risks and enables full reflow soldering without parameter shift |
| Five equally spaced taps | Enables uniform timing interpolation across 100–500ns range without external dividers or PLLs |
| Leading- and trailing-edge fidelity | Maintains pulse width within ±1ns deviation - critical for clock/data recovery and strobe generation |
| Industrial temperature support | Guaranteed performance from -40°C to +85°C - suitable for factory automation and outdoor instrumentation |
| µMAX-8 RoHS-compliant package | 3mm × 3mm footprint with lead(Pb)-free terminations - meets IPC/JEDEC reflow standards (260°C peak) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100Z-500+ | Same electrical specs and delay values, but in 8-pin SO (150 mil) package - larger footprint (4.9mm × 6.0mm) and higher thermal mass | Better suited for prototyping or manual assembly; less optimal for high-density routing or thermal cycling stress | Select DS1100Z-500+ when board real estate allows and hand-soldering or socketing is preferred |
| MAX96702ASA+ | Not a delay line - serial deserializer with embedded timing recovery; no fixed tap outputs or deterministic ns-level delays | Targets high-speed video backhaul, not discrete timing alignment; requires clock/data recovery loop | Not functionally comparable - only consider if migrating to serialized interface architecture with integrated timing |
Compared with DS1100U-500+, DS1100Z-500+ offers identical timing performance in a larger SO package, while MAX96702ASA+ serves a fundamentally different system role-making DS1100U-500+ the sole direct silicon delay solution for compact, fixed-tap timing needs.

FAQ
What is the nominal delay value for each tap of the DS1100U-500+?
The DS1100U-500+ provides five fixed tap delays: TAP 1 = 100ns, TAP 2 = 200ns, TAP 3 = 300ns, TAP 4 = 400ns, and TAP 5 = 500ns. These values are factory-trimmed and specified at +25°C and 5V, with tolerances scaling over temperature and voltage per the datasheet's AC Electrical Characteristics table.
Is the DS1100U-500+ compatible with 3.3V logic systems?
No, the DS1100U-500+ is designed exclusively for 5V operation (4.75V to 5.25V). Its input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V) and output drive levels are specified for TTL/CMOS 5V families. Interfacing with 3.3V systems requires level translation to avoid undefined logic states or excessive input leakage.
Does the DS1100U-500+ require external configuration or programming?
No, the DS1100U-500+ is a fully passive, unprogrammable delay line. All five tap delays are hardwired during fabrication and require no initialization, clock, or control signals. It functions immediately upon power-up with VCC applied and IN driven-no firmware, registers, or setup sequence needed.
Can the DS1100U-500+ drive modern CMOS loads like 74LVC or 74AUC?
Yes-the DS1100U-500+ specifies drive capability for 10 × 74LS loads, which corresponds to ~1mA low-level and -1mA high-level output current. This exceeds the input current requirements of 74LVC and 74AUC families (typically ±20μA), making it compatible with proper termination and layout practices.
What is the maximum input frequency supported by the DS1100U-500+?
The DS1100U-500+ is characterized at 1MHz input frequency (1μs period), with active current (ICC) specified under that condition. While functional at higher frequencies, delay accuracy degrades near maximum input rate due to layout sensitivity and decoupling limitations-designers should limit input period to ≥2× the longest tap delay (i.e., ≥1μs) for guaranteed spec compliance.
