Analog Devices Inc./Maxim Integrated DS1100Z-30+

Overview

DS1100Z-30+ from Maxim Integrated is a 5-tap silicon delay line providing fixed, equally spaced delays of 6ns, 12ns, 18ns, 24ns, and 30ns at each tap. It operates from a single 5V supply, reproduces both leading and trailing edges with ±4ns tolerance over –40°C to +85°C, and drives up to ten 74LS loads per tap. It is used in digital timing alignment, clock skew correction, and pulse-width adjustment circuits.

For engineers reviewing the DS1100Z-30+ datasheet, DS1100Z-30+ pinout, DS1100Z-30+ application, or DS1100Z-30+ equivalent, key selection criteria include tap delay precision across temperature, TTL/CMOS compatibility, SO-8 package footprint, low-power CMOS operation, and industrial-grade reliability without hybrid construction.

Technical Context

The DS1100Z-30+ implements an all-silicon delay architecture with five discrete, monotonic output taps-each delay is fixed and calibrated at +25°C/5V, with unidirectional variation across voltage and temperature. Delay tolerances are specified as ±4ns (≤40ns delays) or ±13% (>40ns), and edge fidelity is maintained for both rising (t_PLH) and falling (t_PHL) transitions at the 1.5V logic threshold.

It requires no external components, draws ≤50mA active current at 1MHz, and supports vapor-phase, IR, and wave soldering. Input pulse width must exceed 20% of Tap 5 delay (≥6ns), and power-up time is ≤200μs-enabling immediate use after supply stabilization.

Key Specifications

Pinout & Package

DS1100Z-30+ is housed in an 8-pin SOIC (150 mils) package with gull-wing leads, compliant with JEDEC MS-012 and RoHS requirements. Pin 1 is marked by a notch or dot; the device is not polarity-sensitive beyond standard SO orientation.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and timing ICs for industrial, automotive, and communications applications.

The DS1100 series was developed as a silicon-based replacement for hybrid delay lines-targeting cost-sensitive, high-reliability timing functions in digital systems where predictable, fixed delays are required.

FAQ

What is the nominal delay sequence for DS1100Z-30+?

The DS1100Z-30+ provides five equally spaced nominal delays: Tap 1 = 6ns, Tap 2 = 12ns, Tap 3 = 18ns, Tap 4 = 24ns, and Tap 5 = 30ns. These values are calibrated at +25°C and 5V, with monotonic variation across voltage and temperature. Each tap reproduces both rising and falling edges with matched delay characteristics, and the DS1100Z-30+ maintains this spacing without interpolation or configuration.

Is DS1100Z-30+ pin-compatible with other DS1100 variants?

Yes-DS1100Z-30+ shares the same 8-pin SOIC (150 mils) package and pinout as all DS1100Z-xxx variants, including DS1100Z-20+, DS1100Z-50+, and DS1100Z-100+. Pin assignments (IN, TAP1–TAP5, VCC, GND) are identical across the Z-series, enabling drop-in replacement when delay requirements change. The DS1100Z-30+ does not require PCB redesign when substituted within the same Z-family.

Does DS1100Z-30+ require external components to operate?

No-DS1100Z-30+ is a self-contained delay line requiring only a 5V supply and ground. No external resistors, capacitors, or clocks are needed. A 0.1μF ceramic decoupling capacitor is recommended between VCC and GND near the package, but no timing or configuration components are integrated into the DS1100Z-30+ functional operation.

What is the maximum load DS1100Z-30+ can drive per tap?

Each tap of the DS1100Z-30+ can drive up to ten 74LS logic inputs, corresponding to a low-level output current (I_OL) of 12mA and high-level output current (I_OH) of –1mA. This drive strength is verified under worst-case conditions (V_CC = 4.75V, T_A = +85°C), and the DS1100Z-30+ maintains specified delay accuracy even under full load.

How does DS1100Z-30+ handle input pulse width and frequency limits?

The DS1100Z-30+ requires a minimum input pulse width of ≥6ns (20% of Tap 5 delay) and supports input periods down to 1μs (1MHz). At higher frequencies, active current (I_CC) increases beyond the typical 50mA spec, and delay accuracy may degrade due to layout- and decoupling-sensitive effects-so the DS1100Z-30+ is optimized for stable, moderate-frequency digital timing rather than RF or GHz applications.
