Product details
Overview
DS1100U-200+ from Maxim Integrated is a 5-tap silicon delay line in an 8-pin µMAX package, delivering precisely spaced delays of 40ns, 80ns, 120ns, 160ns, and 200ns at 5V operation. It reproduces both leading and trailing edges with ±4ns tolerance over –40°C to +85°C, drives up to 10 LS-TTL loads per tap, and serves in digital timing alignment, pulse shaping, and clock skew correction circuits.
For engineers reviewing the DS1100U-200+ datasheet, DS1100U-200+ pinout, DS1100U-200+ application, or DS1100U-200+ equivalent, key selection criteria include tap delay accuracy across temperature, TTL/CMOS compatibility, low-power CMOS operation, and µMAX footprint suitability for high-density PCB layouts.
Technical Context
The DS1100U-200+ implements an all-silicon delay architecture with five fixed, equally spaced output taps referenced to a single input signal. Each tap delivers deterministic propagation delay with matched rising/falling edge precision, and delay variation remains unidirectional across voltage (4.75V–5.25V) and temperature (–40°C to +85°C).
It operates as a passive timing element-no internal logic or configuration registers-and requires no external clock or control signals. Input pulse width must exceed 20% of Tap 5 delay (≥40ns), and power-up time is ≤200μs, enabling immediate use after supply stabilization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | 40ns / 80ns / 120ns / 160ns / 200ns - fixed, equally spaced delays referenced to input edge |
| Delay Tolerance | ±4ns (≤40ns delays) or ±13% (>40ns) over –40°C to +85°C - defines worst-case timing margin for synchronous alignment |
| Supply Voltage | 4.75V to 5.25V - supports standard 5V logic rails with ±5% regulation |
| Output Drive | 12mA sink / –1mA source - sufficient to drive 10× 74LS loads without buffering |
| Input Capacitance | 5pF to 10pF - minimizes loading on preceding stage and preserves signal integrity |
| Power-Up Time | ≤200μs - ensures stable delay behavior immediately after VCC stabilization |
Pinout & Package
DS1100U-200+ uses an 8-pin µMAX package (U8+1 outline, 3mm × 3mm body, 0.65mm pitch), compatible with vapor-phase, IR, and wave soldering. Pin 1 is VCC, pin 5 is IN, pins 2/4/6/8 are TAP1/TAP3/TAP5/TAP2, and pin 7 is TAP4; GND is pin 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Signal Input | Single-ended TTL/CMOS-compatible input accepting 0.0V–3.0V pulses; triggers all five taps simultaneously |
| TAP 1–TAP 5 | Delayed Output Taps | Five independent outputs each delivering identical waveform with fixed, increasing delay; no internal termination required |
| VCC | Power Supply | +5V supply pin; decoupling capacitor (0.1μF) recommended adjacent to pin |
| GND | Ground Reference | Common return path for all signals and supply; must be low-impedance connection to minimize ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid ceramic delay line reliability risks and enables full reflow compatibility |
| Leading/trailing-edge matching | Ensures symmetrical delay for both edges-critical for duty-cycle preservation in clock distribution |
| 5V TTL/CMOS compatibility | Direct interface with legacy and modern logic families without level-shifting circuitry |
| Stable delay over temperature | Unidirectional drift ensures relative tap spacing remains constant-enabling predictable multi-tap timing windows |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000Z-200+ | Hybrid ceramic delay line; ±10% delay tolerance over temperature vs. ±13% for DS1100U-200+; higher power consumption | Legacy replacement only; not RoHS-compliant in base version; larger SO-8 footprint | Choose DS1000Z-200+ only if redesigning legacy boards with existing DS1000 footprints and no lead-free requirement |
| MAX9601EUA+ | Programmable 8-tap delay IC with I²C interface; 1ns resolution; requires configuration; 3.3V-only operation | Used where dynamic delay adjustment is required; not suitable for static, fixed-delay roles like DS1100U-200+ | Choose MAX9601EUA+ when system-level calibration or adaptive timing is needed-not for fixed, set-and-forget delay functions |
Compared with DS1000Z-200+, DS1100U-200+ offers superior temperature stability, smaller µMAX footprint, and guaranteed RoHS compliance; compared with MAX9601EUA+, it eliminates firmware dependency and reduces BOM count for static delay tasks.

FAQ
What is the operating temperature range for DS1100U-200+?
The DS1100U-200+ is specified to operate across –40°C to +85°C. All electrical characteristics-including delay tolerance, output drive, and supply current-are guaranteed within this industrial temperature range. The device maintains unidirectional delay drift across temperature, ensuring consistent relative spacing between taps under thermal stress.
Does DS1100U-200+ require external configuration or programming?
No, DS1100U-200+ is a fully passive, fixed-delay device with no configuration interface, registers, or initialization sequence. It begins delivering accurate delays immediately after power-up (≤200μs), making it ideal for systems where simplicity, predictability, and zero firmware overhead are critical design requirements.
Can DS1100U-200+ drive standard TTL loads directly?
Yes, DS1100U-200+ can drive up to 10 LS-TTL loads per tap, verified under DC and AC conditions per the datasheet. Its output drive capability (12mA sink / –1mA source) meets LS-TTL input current requirements without external buffers, simplifying interconnect in legacy digital systems.
What is the meaning of the "+" suffix in DS1100U-200+?
The "+" suffix in DS1100U-200+ indicates a lead(Pb)-free, RoHS-compliant µMAX package. This designation confirms compliance with EU RoHS Directive 2011/65/EU and guarantees the device meets industry-standard environmental and safety requirements for commercial and industrial deployment.
How does DS1100U-200+ handle input pulse width and rise/fall time?
DS1100U-200+ requires input pulse width ≥20% of Tap 5 delay (≥40ns) and rise/fall times ≤3.0ns (20%–80%). These constraints ensure reliable edge detection at the 1.5V threshold used for delay measurement; violating them may degrade delay accuracy or cause missed taps.
