Product details
Overview
DS1100LZ-75+W from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 15ns, 30ns, 45ns, 60ns, and 75ns across TAP1–TAP5. It operates from 3.0V to 3.6V over –40°C to +85°C, delivers TTL-/CMOS-compatible outputs, and drives up to 10 × 74LS loads per tap. Used in high-speed timing alignment, clock deskewing, and pulse-width adjustment circuits.
For engineers reviewing the DS1100LZ-75+W datasheet, DS1100LZ-75+W pinout, DS1100LZ-75+W application, or DS1100LZ-75+W equivalent, key selection criteria include tap delay precision (±4ns over full temperature range for ≤40ns taps), leading/trailing-edge matching, SO-8 package compatibility, and industrial-grade supply voltage tolerance.
Technical Context
The DS1100LZ-75+W implements an all-silicon delay architecture with five fixed, equally spaced delay taps referenced to a single input signal. Each tap reproduces both rising and falling edges with matched propagation delay, enabling precise edge-aligned timing without external compensation.
It uses low-power CMOS logic with VCC = 3.0V–3.6V, supports 20%–80% input rise/fall times ≤3.0ns, and guarantees output rise/fall times ≤2.5ns. Delay tolerances are specified as ±4ns (for TAP1–TAP3) and ±13% (for TAP4–TAP5) over –40°C to +85°C, per Note 10 in the AC Electrical Characteristics table.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-75 | Same delay values and SO-8 package, but not RoHS-compliant (lead-containing finish) | Restricted to legacy industrial programs exempt from RoHS; identical electrical behavior | Select DS1100LZ-75+W when compliance with EU Directive 2011/65/EU is mandatory |
| DS1100LU-75+W | Identical delay specs and RoHS compliance, but in 8-pin µMAX (U8+1) package (3mm × 3mm vs SO-8's 4.9mm × 6.0mm) | Preferred for space-constrained PCBs; thermal derating differs (362mW vs 470.6mW) | Select DS1100LU-75+W when board area is constrained and reflow profile supports µMAX footprint |
Compared with DS1100LZ-75, the +W variant adds RoHS compliance without performance trade-offs; compared with DS1100LU-75+W, the SO-8 version offers higher power dissipation margin and broader PCB assembly compatibility at the cost of larger footprint.

FAQ
What is the guaranteed delay tolerance for TAP1 on DS1100LZ-75+W over the full temperature range?
The DS1100LZ-75+W guarantees ±4ns delay tolerance for TAP1 (15ns nominal) over –40°C to +85°C, as specified in Note 10 of the AC Electrical Characteristics table. This tolerance applies specifically to taps with delays ≤40ns and reflects initial calibration plus temperature/voltage variation.
Does DS1100LZ-75+W support both rising and falling edge delays with equal accuracy?
Yes, DS1100LZ-75+W is explicitly designed to reproduce both leading and trailing edges with equal precision. The datasheet confirms matched tPLH and tPHL delays across all taps, enabling accurate pulse-width preservation in timing-critical paths.
What is the maximum capacitive load DS1100LZ-75+W can drive per tap while maintaining specified timing?
DS1100LZ-75+W is characterized to drive up to 10 × 74LS loads per tap, equivalent to ~100pF total load capacitance. Driving heavier loads may increase output rise/fall times beyond the specified 2.5ns and degrade delay accuracy due to loading-induced propagation shifts.
Can DS1100LZ-75+W operate from a 3.0V supply and still meet all AC specifications?
Yes, DS1100LZ-75+W is fully specified and tested over VCC = 3.0V to 3.6V. All AC parameters-including delay tolerance, rise/fall time, and output drive-are guaranteed across this range, with active current (ICC) measured at 10mA typical at 1MHz and VCC = max.
Is the DS1100LZ-75+W pinout compatible with other DS1100L variants in SO-8 packages?
Yes, all DS1100LZ-xxx variants in SO-8 share identical pinout and footprint (S8+4 outline). DS1100LZ-75+W maintains full mechanical and electrical compatibility with DS1100LZ-20 through DS1100LZ-500, enabling drop-in replacement across delay values within the same package family.
