Product details

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 from −40°C to +85°C in an 8-pin SO package. It reproduces both leading and trailing edges with equal precision and drives up to 10 LS-TTL loads per tap, used in high-speed timing alignment and signal skew correction.

For engineers reviewing the DS1100LZ-75+ datasheet, DS1100LZ-75+ pinout, DS1100LZ-75+ application, or DS1100LZ-75+ equivalent, key selection factors include tap delay accuracy over temperature/voltage, 3.3V CMOS/TTL compatibility, SO-8 footprint constraints, and edge-fidelity requirements in clock distribution or data strobe conditioning circuits.

Technical Context

The DS1100LZ-75+ implements a fully monolithic silicon delay line-no hybrid or ceramic components-enabling stable, repeatable propagation delays across all five taps. Delay tolerance is ±4ns (for TAP 1–TAP 3) and ±13% (for TAP 4–TAP 5) over −40°C to +85°C at 3.3V, with input-to-output edge fidelity maintained at 1.5V switching thresholds.

It operates as a passive, unidirectional timing element: input logic state propagates through fixed-delay paths without buffering, regeneration, or logic inversion. Each tap output is electrically identical in drive strength (I_OL = 8mA, I_OH = −1mA) and rise/fall time (2.0–2.5ns), supporting synchronous fanout in high-speed digital systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	3.0V to 3.6V - ensures compatibility with 3.3V logic domains and eliminates need for level-shifting in mixed-voltage systems.
Nominal Delays	TAP 1: 15ns, TAP 2: 30ns, TAP 3: 45ns, TAP 4: 60ns, TAP 5: 75ns - enables precise, equally spaced timing offsets for multi-phase sampling or deskew.
Delay Tolerance	±4ns (TAP 1–3), ±13% (TAP 4–5) over −40°C to +85°C - defines worst-case inter-tap skew budget in industrial environments.
Output Drive	8mA sink / 1mA source - supports direct connection to 10 × 74LS loads without external buffers.
Rise/Fall Time	2.0ns to 2.5ns - preserves signal integrity for ≤500MHz edge rates and minimizes jitter accumulation.
Power-Up Time	200μs - guarantees stable delay behavior within microseconds after V_CC stabilization, critical for power-gated systems.

Pinout & Package

DS1100LZ-75+ uses an 8-pin SOIC (150-mil) surface-mount package (package code S8+4), optimized for PCB area efficiency and vapor-phase/IR reflow compatibility.

Pin/Terminal	Circuit Role	Design Meaning
1	IN	Single-ended logic input; accepts TTL/CMOS-compatible signals with VIH ≥ 2.0V, VIL ≤ 0.8V.
2	TAP 2	Second delay output; delivers input signal delayed by 30ns with matched edge fidelity to TAP 1 and TAP 3.
3	TAP 4	Fourth delay output; provides 60ns delay; shares same drive capability and AC specs as other taps.
4	GND	Digital ground reference; must be low-impedance and decoupled near V_CC pin for noise immunity.
5	TAP 5	Fifth delay output; delivers 75ns delay; delay tolerance ±13% over full temperature range.
6	TAP 3	Third delay output; provides 45ns delay; delay tolerance ±4ns over −40°C to +85°C.
7	TAP 1	First delay output; delivers 15ns delay; tightest tolerance (±4ns) makes it suitable for fine-grained timing calibration.
8	V_CC	+3.3V supply; requires local 0.1μF ceramic decoupling; active current ICC = 10mA at 1MHz.

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DS1100LZ-50+	Nominal delays: 10ns/20ns/30ns/40ns/50ns; tighter ±2ns tolerance on TAP 1–TAP 3 at +25°C.	Better suited for sub-25ns fine-timing applications where absolute delay accuracy dominates over range.	Select DS1100LZ-50+ when system-level skew budget is <20ps and operating temperature is limited to 0°C–70°C.
DS1100LZ-100+	Nominal delays: 20ns/40ns/60ns/80ns/100ns; wider spacing supports longer inter-tap intervals.	Preferred for coarse-grained timing control such as burst-mode enable sequencing or asynchronous handshake synchronization.	Choose DS1100LZ-100+ when minimum required delay exceeds 60ns and inter-tap resolution >15ns is acceptable.

Compared with DS1100LZ-50+ and DS1100LZ-100+, the DS1100LZ-75+ uniquely balances mid-range delay coverage (15–75ns) with industrial-temperature tolerance (±4ns on early taps), making it optimal for general-purpose skew correction where both precision and range matter.

FAQ

What is the operating temperature range for DS1100LZ-75+?

The DS1100LZ-75+ is specified for continuous operation from −40°C to +85°C. Its delay tolerances-including ±4ns for TAP 1 to TAP 3-are guaranteed across this full industrial temperature range at 3.0V to 3.6V supply voltage, making DS1100LZ-75+ suitable for harsh-environment deployments like factory automation controllers and outdoor telecom infrastructure.

Does DS1100LZ-75+ require external decoupling capacitors?

Yes, DS1100LZ-75+ requires a 0.1μF ceramic capacitor placed as close as possible to the V_CC (pin 8) and GND (pin 4) pins. This decoupling is essential to suppress supply noise that could modulate delay values or induce jitter; the device draws 10mA at 1MHz, and inadequate bypassing may cause measurable delay variation beyond datasheet tolerances in DS1100LZ-75+.

Can DS1100LZ-75+ drive 74ACT logic inputs directly?

Yes, DS1100LZ-75+ can drive 74ACT inputs directly: its I_OL = 8mA and I_OH = −1mA meet or exceed 74ACT fanout requirements (I_IL = ±1μA, I_OH/I_OL ≈ ±24mA). However, for more than two 74ACT loads per tap, verify voltage margins under worst-case V_CC min (3.0V) and temperature extremes, as DS1100LZ-75+ output levels remain TTL/CMOS-compatible but not rail-to-rail.

How does the "-75" suffix in DS1100LZ-75+ relate to delay accuracy?

The "-75" suffix indicates the device is configured for 75ns nominal delay at TAP 5, with corresponding 15ns/30ns/45ns/60ns at earlier taps. Per Note 10 in the datasheet, DS1100LZ-75+ receives additional 2ns tolerance allowance on TAP 1–TAP 3 delay specs versus standard versions-i.e., ±4ns instead of ±2ns at +25°C-while TAP 4–TAP 5 retain standard ±13% tolerance, confirming DS1100LZ-75+'s design for robust mid-range timing.

Is DS1100LZ-75+ pin-compatible with DS1100LZ-100+?

Yes, DS1100LZ-75+ and DS1100LZ-100+ share identical 8-pin SOIC (150-mil) pinouts, supply connections (V_CC, GND), input (IN), and tap output assignments (TAP 1–TAP 5). No PCB redesign is needed when substituting between these variants-the only functional difference is nominal delay values; thus DS1100LZ-75+ and DS1100LZ-100+ are drop-in replacements for layout-constrained upgrades or downgrades within the DS1100LZ family.
