Product details
Overview
DS1033Z-30 from Dallas Semiconductor (now Maxim Integrated) is a low-voltage, all-silicon 3-channel delay line IC operating at 3.3 V with ±2.0 ns initial delay tolerance and 30 ns nominal delay per output. It provides independent buffered delays for timing alignment in high-speed digital systems, preserving input signal symmetry with precise leading/trailing edge accuracy. Used in clock deskewing, signal synchronization, and FPGA I/O timing calibration.
For engineers reviewing the DS1033Z-30 datasheet, DS1033Z-30 pinout, DS1033Z-30 application, or DS1033Z-30 equivalent, key selection criteria include guaranteed 30 ns delay per channel, ±2.0 ns initial tolerance at +25°C, operation across 2.7–3.6 V supply, 0°C to 70°C industrial temperature range, and SOIC-8 (150-mil) package compatibility.
Technical Context
The DS1033Z-30 implements three independent CMOS logic-buffered delay paths with matched propagation characteristics for tPLH and tPHL. Each channel delivers identical 30 ns nominal delay under VCC = 3.3 V, with edge-preserving architecture ensuring <1 ns skew between rising/falling edges.
It operates within a 2.7–3.6 V supply range and maintains stable delay performance over temperature (0°C to 70°C), with total delay variation of ±5.0 ns at VCC = 2.7 V and ±2.0 ns at VCC = 3.3 V. Input and output logic levels comply with standard TTL/CMOS thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Delay | 30 ns per output - fixed, matched delay across IN1→OUT1, IN2→OUT2, IN3→OUT3 |
| Initial Tolerance | ±2.0 ns at +25°C/VCC=3.3V - defines worst-case static timing margin at room temperature |
| Supply Voltage | 2.7 V to 3.6 V - supports low-power 3.3 V systems with 10% regulation headroom |
| Operating Temp | 0°C to 70°C - qualified for industrial-grade embedded timing applications |
| Output Drive | 8 mA sink / –1 mA source at VCC=2.7V - sufficient to drive one 74F04 gate load |
| Input Leakage | ±1.0 µA - ensures minimal loading on upstream logic sources |
| Rise/Fall Time | 2.0–3.5 ns - preserves signal integrity for sub-100 MHz digital waveforms |
Pinout & Package
DS1033Z-30 is supplied in an 8-pin SOIC package (150-mil width), pin-compatible with industry-standard 8-pin mini-SOIC footprints. The package supports vapor phase, IR, and wave soldering processes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1033M-30 | DIP-8 package instead of SOIC-8; identical electrical specs and 30 ns delay | Suitable for through-hole prototyping or legacy DIP-based systems; not surface-mount compatible | Select DS1033M-30 only when manual assembly or socket-based testing is required |
| MAX9992ETE+ | Programmable 0–31.5 ns delay in 125 ps steps; 3.3 V operation; TQFN-16 package | Supports dynamic delay adjustment via SPI; higher integration but requires configuration interface | Choose MAX9992ETE+ when fine-grained, software-controlled delay tuning is needed |

FAQ
What is the nominal delay value of the DS1033Z-30?
The DS1033Z-30 provides a fixed 30 ns nominal delay on each of its three independent output channels (OUT1, OUT2, OUT3) relative to their corresponding inputs (IN1, IN2, IN3) under standard conditions (VCC = 3.3 V, TA = +25°C). This delay is matched across all channels and specified for both tPLH and tPHL transitions.
Does the DS1033Z-30 support operation at 2.5 V supply voltage?
No, the DS1033Z-30 is not characterized or guaranteed for operation at 2.5 V. Its absolute minimum supply voltage is 2.7 V, and full specification compliance (including delay accuracy and output drive) is ensured only between 2.7 V and 3.6 V. Operation below 2.7 V may result in undefined timing behavior or failure to meet ±2.0 ns initial tolerance.
Can the DS1033Z-30 be used with 5 V logic inputs?
Yes - the DS1033Z-30 accepts 5 V-tolerant inputs. Its VIH threshold is defined as ≥2.0 V, and absolute maximum input voltage is +6.0 V. A 5 V logic signal applied to IN1, IN2, or IN3 will be correctly recognized as HIGH without level shifting, provided the input current remains within ±1.0 µA leakage limits.
Is the DS1033Z-30 pin-compatible with the DS1033M-30?
Yes, the DS1033Z-30 (SOIC-8) and DS1033M-30 (DIP-8) share identical pin functions and numbering. Both use the same 1–8 pin order: IN1, IN2, IN3, GND, VCC, OUT3, OUT1, OUT2. However, physical mounting differs - SOIC requires reflow soldering, while DIP supports through-hole assembly or socketing.
What is the maximum output load capacitance supported by the DS1033Z-30?
The DS1033Z-30 is characterized with a 15 pF capacitive load per output, matching the input capacitance of one 74F04 gate. Driving loads exceeding 15 pF may degrade rise/fall times beyond the specified 2.0–3.5 ns range and increase delay variation. For heavier loads, external buffer amplification is recommended to maintain timing integrity.
