Analog Devices Inc./Maxim Integrated DS1100Z-40+

Overview

DS1100Z-40+ from Maxim Integrated is a 5-tap silicon delay line IC providing fixed, equally spaced delays of 8ns, 16ns, 24ns, 32ns, and 40ns at each tap, operating at 5V with ±4ns delay tolerance over –40°C to +85°C, and capable of driving up to 10 LS-TTL loads per output-used in digital timing alignment, pulse shaping, and clock deskew circuits.

For engineers reviewing the DS1100Z-40+ datasheet, DS1100Z-40+ pinout, DS1100Z-40+ application, or DS1100Z-40+ equivalent, key selection considerations include tap delay precision across temperature, TTL/CMOS compatibility, SO-8 package footprint, low-power CMOS operation, and leading/trailing edge matching for high-fidelity signal replication.

Technical Context

The DS1100Z-40+ implements an all-silicon delay architecture with five discrete, monotonic delay paths-each reproducing input logic state after a fixed, factory-trimmed interval. Delay variation is unidirectional: all taps slow or speed together under voltage or temperature change, preserving inter-tap spacing.

It operates exclusively at 5V (4.75V–5.25V), supports 1MHz input frequency, and guarantees both tPLH and tPHL accuracy within ±4ns over full industrial temperature range. Input-to-output propagation is measured at 1.5V threshold, with rise/fall times ≤3ns and pulse width ≥500ns.

Key Specifications

Pinout & Package

DS1100Z-40+ uses an 8-pin SOIC (150-mil) surface-mount package with exposed pad not connected. Pinout is standardized across DS1100Z variants and matches JEDEC MS-012AC outline.

Equivalent & Alternatives

The following parts are listed as comparable options for similar delay line applications.

Compared with DS1100U-40+, the DS1100Z-40+ offers identical timing performance in a larger, more manufacturable SO-8 package; compared with DS1023-40+, it trades some room-temperature precision for broader temperature stability and greater tap flexibility-making DS1100Z-40+ optimal for industrial systems requiring robust, field-deployable delay alignment.

FAQ

What is the nominal delay value for each tap of the DS1100Z-40+?

The DS1100Z-40+ provides five equally spaced delays: TAP 1 = 8ns, TAP 2 = 16ns, TAP 3 = 24ns, TAP 4 = 32ns, and TAP 5 = 40ns. These values are factory-trimmed and specified at +25°C and 5V, with ±4ns tolerance maintained across the full –40°C to +85°C operating range. Each tap reproduces both rising and falling edges with matched delay characteristics.

Is the DS1100Z-40+ pin-compatible with earlier DS1100Z variants?

Yes-the DS1100Z-40+ shares identical pinout, package (8-pin SO), and electrical interface with all DS1100Z-xxx variants. The "-40" suffix denotes total delay at TAP 5; other suffixes (e.g., -25, -100) retain the same pin assignments and DC/AC specifications. No PCB changes are required when substituting within the DS1100Z family.

Can the DS1100Z-40+ drive standard TTL loads directly?

Yes-the DS1100Z-40+ is rated to drive up to 10 LS-TTL loads per tap, with IOL = 12mA and IOH = –1mA at VCC = 4.75V. Its output structure meets TTL voltage thresholds (VOH ≥ 2.4V, VOL ≤ 0.5V) and is fully compatible with 74LS, 74F, and CMOS logic families without external buffers or level shifters.

Does the DS1100Z-40+ require external passive components for stable operation?

Yes-a 0.1μF ceramic decoupling capacitor must be placed between VCC (Pin 1) and GND (Pin 8), as close as possible to the device. This minimizes supply noise-induced delay variation. No pull-up/down resistors or termination networks are needed-the DS1100Z-40+ has internally optimized input/output impedance and operates reliably with clean 5V supply and proper PCB layout.

What does the "+" suffix in DS1100Z-40+ indicate?

The "+" suffix in DS1100Z-40+ indicates a lead(Pb)-free, RoHS-compliant SO-8 package. It reflects compliance with EU Directive 2011/65/EU and maximizes compatibility with modern reflow profiles-including lead-free soldering at up to +260°C. The "+" does not affect electrical performance, timing specs, or pinout-it is purely a packaging and environmental designation.
