Analog Devices Inc./Maxim Integrated DS1100LZ-300

Overview

DS1100LZ-300 from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 60ns, 120ns, 180ns, 240ns, and 300ns across TAP1–TAP5. It operates from 3.0V to 3.6V over –40°C to +85°C, reproduces both leading and trailing edges with ±4ns tolerance (≤40ns taps) or ±13% (≥40ns taps), and drives up to 10 LS-TTL loads per tap. Used in high-speed timing alignment, clock skew correction, and pulse-width adjustment circuits.

For engineers reviewing the DS1100LZ-300 datasheet, DS1100LZ-300 pinout, DS1100LZ-300 application, or DS1100LZ-300 equivalent, key selection criteria include tap delay accuracy over temperature/voltage, TTL/CMOS compatibility, SO-8 package footprint, and edge-fidelity performance in synchronous logic interfaces.

Technical Context

The DS1100LZ-300 implements an all-silicon delay architecture with five fixed, equally spaced delay taps referenced to a single input signal. Each tap delivers identical propagation characteristics for rising and falling edges, with delay variation tightly coupled across taps under voltage or temperature shifts-ensuring monotonic tracking.

It uses CMOS logic-level inputs and outputs, supports 3.3V supply only, and maintains stable delay values without external components or calibration. The device is characterized for industrial temperature range (–40°C to +85°C) and specified with ±13% delay tolerance at TAP5 (300ns) under full operating conditions.

FAQ

What is the nominal delay value for TAP5 of the DS1100LZ-300?

The DS1100LZ-300 has a nominal TAP5 delay of 300ns, as indicated by the "-300" suffix. This value is measured at +25°C and VCC = 3.3V, with tolerance of ±13% over the full industrial temperature range (–40°C to +85°C) and supply voltage range (3.0V to 3.6V). All five taps-TAP1 through TAP5-are equally spaced, yielding 60ns increments.

Does the DS1100LZ-300 support both rising and falling edge delay accuracy?

Yes, the DS1100LZ-300 is explicitly designed to reproduce both leading and trailing edges with equal precision. Its datasheet confirms identical tPLH (rising-edge delay) and tPHL (falling-edge delay) specifications across all taps. This ensures pulse-width integrity and eliminates duty-cycle distortion when used in edge-sensitive timing paths such as clock gating or strobe generation.

What package type is used for the DS1100LZ-300?

The DS1100LZ-300 uses an 8-pin SO (Small Outline) package with 150-mil body width, designated as S8+4 in Maxim's package coding. It is RoHS-compliant (lead-free), vapor-phase and IR solderable, and shares the same footprint as industry-standard SOIC-8 devices-enabling compatibility with existing pick-and-place and reflow processes.

Can the DS1100LZ-300 drive standard TTL loads directly?

Yes, each tap of the DS1100LZ-300 can drive up to 10 LS-TTL loads, verified by its IOL = 8mA (low-level) and IOH = –1mA (high-level) specifications at minimum VCC. This capability allows direct interfacing with legacy 74LS logic without level-shifting or buffer amplification, simplifying integration into mixed-technology systems.

Is the DS1100LZ-300 pin-compatible with other DS1100L variants?

Yes, all DS1100LZ-xxx variants-including DS1100LZ-300-share identical pinout, package, and electrical interface. The only difference is the nominal delay values per tap, defined by the suffix (e.g., -300). This uniformity allows design reuse across timing variants without PCB changes, provided the selected delay values meet system timing requirements.
