Product details

Overview

DS1033Z-15 from Dallas Semiconductor (now Maxim Integrated) is a low-voltage, all-silicon 3-channel delay line IC operating at 2.7V–3.6V with nominal 15 ns per-output delay, ±1.5 ns initial tolerance, and precise leading/trailing edge matching for signal integrity in timing-critical digital systems.

For engineers reviewing the DS1033Z-15 datasheet, DS1033Z-15 pinout, DS1033Z-15 application, or DS1033Z-15 equivalent, this device serves as a stable, solder-compatible replacement for quartz-based or RC delay solutions in clock deskewing, pulse width adjustment, and synchronous logic alignment where sub-nanosecond edge fidelity and voltage/temperature stability are required.

Technical Context

The DS1033Z-15 implements three independent buffered CMOS delay paths within a single 8-pin SOIC package, each delivering identical 15 ns propagation delay (tPLH/tPHL) under nominal conditions (25°C, VCC = 3.3 V). It uses silicon-based delay elements-not RC networks or transmission lines-ensuring monotonic, voltage- and temperature-stable performance.

Delay accuracy is specified for both rising and falling edges (tPLH and tPHL), preserving input signal symmetry. Tolerance over full operating range (0°C to 70°C, VCC = 2.7 V to 3.6 V) is ±1.5 ns at 3.3 V and ±2.0 ns at 2.7 V, with output rise/fall times ≤3.5 ns into 15 pF load.

Key Specifications

Parameter	Value and Actual Design Meaning
Delay per output	15 ns - fixed, matched delay across IN1→OUT1, IN2→OUT2, IN3→OUT3
Initial delay tolerance	±1.5 ns at +25°C, VCC = 3.3 V - enables tight setup/hold margin control
Supply voltage range	2.7 V to 3.6 V - compatible with modern 3.3 V logic families and low-power systems
Edge precision	Matched tPLH and tPHL - maintains 50% duty cycle integrity for clock distribution
Output drive strength	IOL = 8 mA, IOH = –1 mA at VCC = 2.7 V - sufficient to drive one 74F04 gate directly
Input capacitance	10 pF max - minimizes loading on upstream drivers and preserves signal edge rate
Operating temperature	0°C to 70°C - commercial-grade rating suitable for industrial control and telecom infrastructure

Pinout & Package

DS1033Z-15 is housed in an 8-pin SOIC (150-mil) package with gull-wing leads, compatible with vapor phase, IR, and wave soldering processes. Pin 1 is marked by a beveled corner or dot; substrate pins (Sub) are internally connected and must remain unconnected externally.

Pin/Terminal	Circuit Role	Design Meaning
IN1, IN2, IN3	Digital input signals	Three independent TTL/CMOS-compatible inputs accepting 0.0 V–3.0 V swing
OUT1, OUT2, OUT3	Buffered delayed outputs	Each delivers identical 15 ns delay with matched rise/fall characteristics
VCC	Positive supply	Must be decoupled locally; supports 2.7 V–3.6 V operation
GND	Ground reference	Common return for all inputs, outputs, and internal circuitry
NC	No connection	Unbonded pad; no external connection permitted
Sub (Pins 4 & 5)	Internal substrate tie	Internally connected to die substrate; must not be externally wired

Key Features

Feature	Design Value
All-silicon delay architecture	Eliminates drift, aging, and environmental sensitivity inherent in RC or crystal-based delays
Three independent buffered delays	Enables parallel delay of multiple control or clock signals without cross-talk or loading effects
Leading and trailing edge precision	Preserves input waveform symmetry - critical for duty-cycle-sensitive applications like clock recovery
±1.5 ns initial tolerance	Reduces need for system-level calibration or trimming in production test
SOIC and DIP packaging options	Supports both automated SMT assembly (DS1033Z) and through-hole prototyping (DS1033M)

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DS1033M-15	Same electrical specs; 8-pin DIP package instead of SOIC	Preferred for through-hole prototyping or legacy board rework	Select DS1033M-15 when manual assembly or socket-based evaluation is required
MAX9622EUA+	Single 15 ns delay channel; 8-pin µMAX package; higher ICC (35 mA)	Limited to single-signal delay; lacks triple-output integration	Choose MAX9622EUA+ only if space-constrained layout prohibits 8-pin SOIC or triple delay is unnecessary

Compared with DS1033Z-15, DS1033M-15 offers identical timing performance in a through-hole format, while MAX9622EUA+ trades channel count and package size for slightly higher power consumption - making DS1033Z-15 optimal for multi-signal synchronization in compact SMT designs.

FAQ

What is the operating voltage range for DS1033Z-15?

The DS1033Z-15 operates over a supply voltage range of 2.7 V to 3.6 V, with nominal performance characterized at 3.3 V ±0.1 V. At 2.7 V, delay tolerance increases to ±2.0 ns, and output drive capability remains functional per DC specifications - enabling robust use in brown-out or battery-backed systems where DS1033Z-15 maintains defined timing behavior.

Does DS1033Z-15 support both rising and falling edge delays?

Yes, DS1033Z-15 specifies matched propagation delays for both rising (tPLH) and falling (tPHL) edges - each at 15 ns under nominal conditions. This edge symmetry ensures preserved duty cycle and minimal jitter accumulation in clock distribution or pulse-width modulation applications where DS1033Z-15 is deployed.

Can DS1033Z-15 be used in place of DS1033M-15?

DS1033Z-15 and DS1033M-15 share identical electrical specifications and timing performance; the only difference is package type - SOIC versus DIP. DS1033Z-15 is not a drop-in replacement on DIP footprints, but it is a direct functional substitute when migrating to surface-mount assembly. For DS1033Z-15, ensure PCB land pattern matches 150-mil SOIC dimensions and thermal profile supports lead-free soldering.

What is the maximum load capacitance supported by DS1033Z-15 outputs?

DS1033Z-15 is characterized with a 15 pF capacitive load per output, matching the input capacitance of one 74F04 gate. Rise/fall times are guaranteed ≤3.5 ns under this condition. Driving heavier loads may increase delay and degrade edge fidelity; for loads >15 pF, buffer amplification or layout optimization is recommended to maintain DS1033Z-15 timing accuracy.

Is DS1033Z-15 suitable for automotive applications?

No, DS1033Z-15 is rated for 0°C to 70°C operation and is not qualified to AEC-Q100 standards. Its commercial temperature grade makes it appropriate for industrial control, telecom infrastructure, and computing systems - but not for under-hood automotive environments. For automotive-grade alternatives, consult Maxim's automotive-qualified timing portfolio; DS1033Z-15 remains ideal for non-automotive timing-critical applications.
