Product details
Overview
DS1100LZ-250 from Maxim Integrated is a 3.3V, 5-tap silicon delay line delivering precise, fixed delays of 50ns, 100ns, 150ns, 200ns, and 250ns across equally spaced taps. It operates over -40°C to +85°C, supports TTL/CMOS logic levels, and drives up to 10 × 74LS loads per tap. Used in high-speed timing alignment, clock skew correction, and pulse-width adjustment circuits.
For engineers reviewing the DS1100LZ-250 datasheet, DS1100LZ-250 pinout, DS1100LZ-250 application, or DS1100LZ-250 equivalent, key selection criteria include tap delay accuracy (±4ns at -40°C to +85°C for ≤40ns delays, ±13% for >40ns), 3.3V supply range (3.0V–3.6V), and SO-8 surface-mount packaging compatibility with vapor-phase and IR reflow soldering.
Technical Context
The DS1100LZ-250 implements an all-silicon delay architecture with five fixed-output taps, each reproducing both leading and trailing edges with equal precision. Delay values are calibrated at +25°C and VCC = 3.3V, with unidirectional temperature/voltage drift-e.g., if TAP 1 slows, all taps slow proportionally.
It features low-power CMOS design, 5pF typical input capacitance, and 2.0–2.5ns output rise/fall times. Input-to-tap delay tolerance is specified as ±4ns (for delays ≤40ns) or ±13% (for delays >40ns) across the full industrial temperature range (-40°C to +85°C).

Applications
| Digital Signal Skew Correction | High-Speed Clock Distribution |
|---|---|
Use Scenario: Aligning data and clock signals arriving at different times due to trace-length mismatch in FPGA or ASIC interfaces. IC Role / Device Role / Timing Role: DS1100LZ-250 provides calibrated, fixed delays on individual signal paths to eliminate setup/hold violations. Use Value: Enables deterministic timing closure without custom PCB routing or active PLL-based deskew-reduces board layer count and debug time. | Use Scenario: Distributing a master clock to multiple synchronous peripherals (e.g., ADCs, DACs, memory controllers) with matched propagation delay. IC Role / Device Role / Timing Role: DS1100LZ-250 acts as a passive, low-jitter delay node to balance clock path lengths across parallel channels. Use Value: Achieves sub-nanosecond inter-channel skew control-improves sampling accuracy and system SNR without adding jitter from active clock buffers. |
| Pulse Width Adjustment | Logic Glitch Suppression |
Use Scenario: Extending or shortening narrow pulses in digital control loops (e.g., PWM gate drivers, safety interlocks). IC Role / Device Role / Timing Role: DS1100LZ-250 generates delayed versions of the same signal to create AND/OR combinations that reshape pulse duration. Use Value: Provides repeatable, temperature-stable pulse stretching (e.g., 50ns–250ns steps) without analog components or microcontroller intervention. | Use Scenario: Removing sub-10ns glitches caused by asynchronous signal transitions in bus arbitration or interrupt handling. IC Role / Device Role / Timing Role: DS1100LZ-250 feeds identical signals through two taps (e.g., TAP1 and TAP2), then XORs outputs to nullify narrow spikes. Use Value: Eliminates metastability risk in critical control paths using only passive, zero-power delay elements-no additional power or latency overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-200 | Delivers 40ns/80ns/120ns/160ns/200ns taps - shorter maximum delay than DS1100LZ-250 | Suitable where 200ns max delay suffices; reduces timing margin but improves noise immunity at lower delays | Select when system timing budget allows tighter delay ceiling and higher tolerance to delay variation is acceptable |
| DS1100LZ-300 | Delivers 60ns/120ns/180ns/240ns/300ns taps - extends maximum delay by 50ns over DS1100LZ-250 | Required for longer pipeline stages or wider skew compensation windows; increases propagation uncertainty at extreme temperatures | Choose when 250ns is insufficient and system design accommodates ±13% tolerance at 300ns tap |
Compared with DS1100LZ-200 and DS1100LZ-300, the DS1100LZ-250 offers optimal balance between delay resolution (50ns step), maximum span (250ns), and industrial-grade tolerance-making it ideal for mid-range timing alignment tasks where both precision and headroom matter.

FAQ
What is the operating voltage range for DS1100LZ-250?
The DS1100LZ-250 operates over a supply voltage range of 3.0V to 3.6V, with typical performance characterized at 3.3V. This 3.3V-specific design ensures compatibility with modern low-voltage logic families while maintaining robust noise margins-VIH ≥ 2.0V and VIL ≤ 0.8V guarantee reliable switching across the full voltage range. The DS1100LZ-250 does not support 5V operation.
How accurate are the tap delays on DS1100LZ-250 across temperature?
For DS1100LZ-250, tap delays ≤40ns (TAP1–TAP3) exhibit ±4ns tolerance over -40°C to +85°C; delays >40ns (TAP4–TAP5) show ±13% tolerance over the same range. All taps track unidirectionally with temperature and voltage changes-meaning relative spacing remains consistent. This behavior is confirmed in the DS1100L datasheet AC Electrical Characteristics table and Test Conditions section.
Can DS1100LZ-250 drive standard TTL loads directly?
Yes, DS1100LZ-250 can drive up to 10 × 74LS loads per tap, verified under standard test conditions (VCC = 3.3V, TA = +25°C). Its IOL = 8mA and IOH = -1mA specifications meet 74LS input current requirements. For heavier loads or longer traces, external buffering is recommended-but DS1100LZ-250 eliminates need for discrete resistors or gate arrays in most medium-speed digital timing applications.
What package type is used for DS1100LZ-250?
DS1100LZ-250 is supplied in an 8-pin SO (Small Outline) package with 150-mil body width, designated as "SO" in Maxim's ordering nomenclature. This RoHS-compliant, lead(Pb)-free package supports vapor-phase and IR reflow soldering per JEDEC standards, and its land pattern is documented under Maxim package code S8+4 (Outline No. 21-0041).
Does DS1100LZ-250 require external decoupling capacitors?
Yes, DS1100LZ-250 requires a 0.1μF ceramic decoupling capacitor placed as close as possible to the VCC pin (Pin 8) and GND pin (Pin 4). This is explicitly stated in the DS1100L datasheet Test Conditions section and is essential to suppress supply noise that could degrade delay accuracy or cause output instability-especially during fast edge transitions at the input.
