Analog Devices Inc./Maxim Integrated DS1100LZ-75

Overview

DS1100LZ-75 from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 15ns (TAP 1), 30ns (TAP 2), 45ns (TAP 3), 60ns (TAP 4), and 75ns (TAP 5), operating over -40°C to +85°C, driving up to 10 LS-TTL loads per tap, and specified for precision edge-aligned timing in high-speed digital synchronization circuits.

For engineers reviewing the DS1100LZ-75 datasheet, DS1100LZ-75 pinout, DS1100LZ-75 application, or DS1100LZ-75 equivalent, key selection factors include tap delay tolerance (±4ns for TAP 1–3 at -40°C to +85°C), 3.3V CMOS/TTL compatibility, SO-8 package footprint, and leading/trailing edge fidelity critical for clock deskew and signal alignment.

Technical Context

The DS1100LZ-75 implements an all-silicon delay path with five fixed, equally spaced taps derived from a monolithic CMOS delay chain. Each tap reproduces both rising and falling edges with matched propagation characteristics, enabling precise pulse-width preservation across all outputs.

It operates within a 3.0V–3.6V supply range and delivers stable delay values with ±4ns absolute tolerance (TAP 1–3) and ±13% relative tolerance (TAP 4–5) over full industrial temperature range, with input-to-output delay measured at 1.5V thresholds and rise/fall times ≤2.5ns.

Key Specifications

Pinout & Package

DS1100LZ-75 is housed in an 8-pin SO (Small Outline, 150-mil width) surface-mount package compliant with JEDEC MS-012, optimized for automated assembly and PCB area efficiency.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a semiconductor company specializing in precision analog, mixed-signal, and high-reliability timing solutions for industrial, communications, and computing markets.

The DS1100L series was designed as an economical, silicon-based replacement for hybrid delay lines-targeting applications demanding repeatable, low-drift timing in space-constrained PCBs.

FAQ

What is the maximum operating frequency supported by the DS1100LZ-75?

The DS1100LZ-75 does not specify a maximum operating frequency but is characterized for input pulse widths ≥20% of the TAP 5 delay (i.e., ≥15ns for DS1100LZ-75). At 1MHz test frequency, active current is 10mA; higher frequencies increase ICC. For reliable operation, input period should exceed 2×tWI, and layout decoupling is critical above 50MHz.

Does the DS1100LZ-75 support both rising and falling edge delays with equal accuracy?

Yes, the DS1100LZ-75 is explicitly designed to reproduce both leading and trailing edges with equal precision. The datasheet confirms matched tPLH and tPHL tolerances across all taps, and Figure 2's timing diagram shows symmetrical delay behavior-ensuring pulse width integrity is preserved at every output.

What is the meaning of the "-75" suffix in DS1100LZ-75?

The "-75" suffix in DS1100LZ-75 indicates the nominal delay at TAP 5 is 75ns, with corresponding nominal delays of 15ns (TAP 1), 30ns (TAP 2), 45ns (TAP 3), and 60ns (TAP 4). Per Note 10, this variant has +2ns added tolerance on minimum input-to-tap delay for TAP 1–3 versus standard versions.

Can the DS1100LZ-75 drive standard 74LS logic inputs directly?

Yes, each tap of the DS1100LZ-75 is rated to drive up to 10 74LS loads. With IOL = 8mA and IOH = -1mA at VCC = 3.0V, it meets the DC interface requirements of 74LS families while maintaining TTL-compatible voltage thresholds-no buffer stage is required in typical implementations.

Is the DS1100LZ-75 RoHS-compliant and lead(Pb)-free?

Yes, the DS1100LZ-75 is RoHS-compliant and lead(Pb)-free. The "Z" in the part number denotes the SO-8 package, and the "+" suffix (e.g., DS1100LZ-75+) explicitly indicates lead-free/RoHS compliance. Standard DS1100LZ-75 devices shipped after July 2015 meet JEDEC J-STD-609A Class 1 marking requirements.
