Analog Devices Inc./Maxim Integrated DS1100Z-500+

Overview

DS1100Z-500+ from Maxim Integrated is a 5-tap silicon delay line providing precisely spaced 100ns, 200ns, 300ns, 400ns, and 500ns delays at each tap under 5V operation. It reproduces both leading and trailing edges with equal precision, drives up to 10 LS-TTL loads per tap, and operates across -40°C to +85°C. It serves in digital timing alignment, pulse shaping, and clock deskew applications on industrial control PCBs.

For engineers reviewing the DS1100Z-500+ datasheet, DS1100Z-500+ pinout, DS1100Z-500+ application, or DS1100Z-500+ equivalent, key selection criteria include tap delay accuracy over temperature, edge fidelity for high-speed logic interfaces, TTL/CMOS compatibility, SO-8 package footprint, and lead-free compliance for RoHS-constrained designs.

Technical Context

The DS1100Z-500+ implements an all-silicon delay architecture with five fixed, equally spaced delay taps derived from a monolithic CMOS timing circuit. Each tap delivers deterministic propagation delay with ±4ns (≤40ns) or ±13% (>40ns) tolerance over -40°C to +85°C at 5V.

It features TTL/CMOS-compatible input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V), low-power CMOS operation (ICC = 30–50mA typical), and supports vapor-phase, IR, and wave soldering. Input-to-output delay is measured at the 1.5V logic threshold for both rising (tPLH) and falling (tPHL) edges.

Key Specifications

Pinout & Package

DS1100Z-500+ uses an 8-pin SOIC (150 mils) package with exposed pad not present; pinout is identical to standard SO-8 layout per Maxim outline S8+4.

FAQ

What is the nominal delay value for each tap of the DS1100Z-500+?

The DS1100Z-500+ provides five equally spaced nominal delays: TAP1 = 100ns, TAP2 = 200ns, TAP3 = 300ns, TAP4 = 400ns, and TAP5 = 500ns. These values are specified at +25°C and 5V, with tolerance bands defined across the full -40°C to +85°C operating range. Each tap reproduces both rising and falling edges with matched delay characteristics, ensuring consistent pulse width preservation in the DS1100Z-500+.

Is the DS1100Z-500+ compatible with TTL and CMOS logic families?

Yes, the DS1100Z-500+ features TTL/CMOS-compatible input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V) and outputs that drive up to 10 LS-TTL loads per tap. Its 5V supply operation and logic-level specifications allow direct interfacing with standard 74LS, 74HC, and other 5V logic families without level shifters. This compatibility is verified across the full industrial temperature range and is documented in the DS1100Z-500+ DC electrical characteristics table.

Does the DS1100Z-500+ require external passive components for basic operation?

No, the DS1100Z-500+ operates as a standalone delay element with no external timing components required. Only a local 0.1µF ceramic bypass capacitor between VCC (Pin 1) and GND (Pin 8) is recommended for noise suppression. No pull-up/down resistors, termination networks, or RC networks are needed - the DS1100Z-500+ integrates all timing functionality in monolithic silicon, simplifying layout and reducing BOM count.

What is the maximum output load the DS1100Z-500+ can drive per tap?

Each tap of the DS1100Z-500+ is rated to drive up to 10 LS-TTL loads, equivalent to a total capacitive load of approximately 100pF and DC current sufficient for standard logic fanout. This drive capability is maintained across the full -40°C to +85°C temperature range and 4.75V–5.25V supply voltage. Exceeding this load may degrade delay accuracy and edge fidelity, so buffer amplifiers should be used for heavier loads - a key design constraint of the DS1100Z-500+.

How does the DS1100Z-500+ handle input pulse width and rise/fall time variations?

The DS1100Z-500+ specifies minimum input pulse width (tWI) of 20% of the TAP5 delay (i.e., ≥100ns for DS1100Z-500+) and recommends input rise/fall times ≤3.0ns (20%–80%). Within these limits, delay accuracy remains within datasheet tolerances. Slower edges or narrower pulses increase jitter and reduce timing predictability - particularly near maximum frequency operation. These constraints are explicitly defined in the DS1100Z-500+ AC Electrical Characteristics and Test Conditions sections.
