Product details
Overview
DS1100U-25+ from Maxim Integrated is a 5-tap silicon delay line in an 8-pin µMAX package, delivering precisely spaced 5ns, 10ns, 15ns, 20ns, and 25ns delays at 5V supply. It reproduces both leading and trailing edges with ±4ns tolerance over –40°C to +85°C and drives up to 10 LS-TTL loads per tap. Used in digital timing alignment, clock skew correction, and pulse-width adjustment circuits.
For engineers reviewing the DS1100U-25+ datasheet, DS1100U-25+ pinout, DS1100U-25+ application, or DS1100U-25+ equivalent, key selection factors include tap delay precision across temperature, TTL/CMOS compatibility, low-power CMOS operation, 5V supply requirement, and µMAX package footprint constraints for high-density PCB layouts.
Technical Context
The DS1100U-25+ implements a monolithic all-silicon delay architecture-no external components or trimming required-with five fixed, equally spaced delay taps referenced to a single input signal. Each tap delivers deterministic propagation delay with matched rise/fall edge fidelity.
It operates exclusively at 5V (4.75V–5.25V), supports full industrial temperature range (–40°C to +85°C), and maintains delay stability via voltage- and temperature-compensated design-delays vary unidirectionally across conditions, preserving tap-to-tap spacing integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | 5ns / 10ns / 15ns / 20ns / 25ns - fixed, equally spaced delays from single input, enabling precise multi-point timing sampling |
| Supply Voltage | 4.75V to 5.25V - requires stable 5V rail; no internal regulation; incompatible with 3.3V systems without level shifting |
| Delay Tolerance | ±4ns (≤40ns delays) over –40°C to +85°C - ensures predictable timing margin in industrial environments |
| Output Drive | 12mA sink / –1mA source - sufficient for direct interface to 74LS logic; not intended for bus termination or high-capacitance loads |
| Input Capacitance | 5pF to 10pF - low loading enables clean signal integrity with minimal reflection on fast edges |
| Power Consumption | 30mA to 50mA active current at 1MHz - scales with frequency; higher frequencies increase ICC nonlinearly |
Pinout & Package
DS1100U-25+ uses an 8-pin µMAX package (U8+1 outline, 3mm × 3mm, 0.65mm pitch), compatible with vapor-phase, IR, and wave soldering. Pin 1 is VCC; pin 5 is IN; pins 2, 4, 6, 7, and 8 are TAP1–TAP5 respectively; pin 3 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Positive supply | Must be decoupled locally with 0.1µF ceramic; no internal bypassing; noise sensitivity increases above 5.25V |
| TAP 1 (Pin 2) | First delayed output | Delivers 5ns-delayed replica of input; same edge fidelity as input; drives ≤10 LS-TTL loads |
| GND (Pin 3) | Reference ground | Shared return path for all outputs; must connect to low-impedance ground plane to minimize jitter |
| TAP 3 (Pin 4) | Third delayed output | Delivers 15ns-delayed signal; matches TAP1/TAP2/TAP4/TAP5 delay tracking across voltage/temperature |
| IN (Pin 5) | Signal input | Accepts TTL/CMOS logic levels; 5pF–10pF input capacitance; 3ns max rise/fall time recommended |
| TAP 2 (Pin 6) | Second delayed output | Delivers 10ns-delayed signal; electrically identical to other taps except delay value |
| TAP 4 (Pin 7) | Fourth delayed output | Delivers 20ns-delayed signal; delay variation remains correlated with other taps under thermal/voltage drift |
| TAP 5 (Pin 8) | Fifth delayed output | Delivers 25ns-delayed signal; longest fixed delay in this variant; used for final-stage timing alignment |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid packaging reliability risks and aging drift; enables 100% wafer-level test and traceable lot control |
| Equal tap spacing | Guarantees consistent incremental delay (5ns steps); simplifies timing diagram analysis and setup/hold verification |
| Leading- and trailing-edge accuracy | Preserves pulse width integrity-critical for clock stretching, strobe generation, and synchronous data capture |
| TTL/CMOS compatibility | Direct interface to legacy 74LS, 74HC, and modern microcontroller GPIO without level shifters or buffers |
| Industrial temperature support | Validated operation from –40°C to +85°C with no derating-suitable for automotive body control and industrial PLC modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000Z-25+ | Hybrid construction; larger SO-8 footprint; ±5% delay tolerance vs. ±4ns absolute for DS1100U-25+ | Higher power consumption; less stable over temperature; limited to commercial grade unless specified | Choose only if legacy DS1000 footprint reuse is mandatory; not recommended for new designs requiring precision or industrial temp range |
| MAX9601EUA+ | Programmable 8-tap delay; SPI interface; 3.3V operation; ±50ps resolution; higher cost and complexity | Requires firmware integration; supports dynamic delay adjustment; unsuitable for static, fixed-delay use cases | Select when variable delay or fine-grained control is needed; DS1100U-25+ remains optimal for simple, low-cost, fixed-tap timing |
Compared with DS1000Z-25+, DS1100U-25+ offers tighter absolute delay tolerance and superior temperature stability in a smaller µMAX package; versus MAX9601EUA+, it provides lower BOM cost and zero-firmware implementation for static delay requirements.

FAQ
What is the maximum operating frequency supported by DS1100U-25+?
The DS1100U-25+ is characterized at 1MHz input frequency, with active current (ICC) specified at that rate. Higher frequencies increase ICC nonlinearly and may degrade delay accuracy due to layout- and decoupling-sensitive effects. For reliable operation, keep input period ≥2× pulse width (e.g., ≥1μs for 500ns pulses), and avoid sustained operation above 5MHz without empirical validation in the target system.
Does DS1100U-25+ support 3.3V logic inputs?
No, DS1100U-25+ is strictly a 5V device: VIH is 2.2V minimum and VIL is 0.8V maximum, but VCC must be 4.75V–5.25V. Applying 3.3V logic directly to IN violates the 5V supply requirement and risks incorrect output behavior or increased ICC. Level translation is required for interfacing with 3.3V systems.
Can DS1100U-25+ be used to delay both rising and falling edges equally?
Yes, DS1100U-25+ is explicitly designed for equal leading- and trailing-edge accuracy. Both tPLH and tPHL are specified with identical tolerances (±4ns over –40°C to +85°C for the -25 version), ensuring pulse width preservation-critical for applications like clock stretching, strobe generation, and synchronous data capture where duty cycle integrity matters.
Is the DS1100U-25+ RoHS-compliant?
Yes, DS1100U-25+ is RoHS-compliant and lead(Pb)-free, as indicated by the "+" suffix in the part number. The µMAX package (U8+1 outline) meets JEDEC J-STD-609A Class 1 marking requirements and is qualified for vapor-phase, IR, and wave soldering per Maxim's package specifications.
How does temperature affect tap-to-tap delay matching in DS1100U-25+?
In DS1100U-25+, all taps track unidirectionally with temperature-e.g., if TAP1 slows down, TAP2–TAP5 slow by proportionally similar amounts. This preserves relative spacing (5ns steps) across –40°C to +85°C, making inter-tap delay differences highly stable. Absolute delay shifts occur, but tap-to-tap matching remains within ±0.5ns, supporting robust multi-point timing alignment.
