Product details
Overview
DS1033Z-20 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 20 ns per-output delay, ±1.5 ns initial tolerance, and precise leading/trailing edge matching for clock/data alignment in high-speed digital systems.
For engineers reviewing the DS1033Z-20 datasheet, DS1033Z-20 pinout, DS1033Z-20 application, or DS1033Z-20 equivalent, this device serves as a stable, solder-compatible timing element for signal skew correction, pulse width adjustment, and synchronous interface synchronization where nanosecond-level delay stability across temperature and supply voltage is required.
Technical Context
The DS1033Z-20 implements three independent, buffered CMOS delay paths within a single 8-pin SOIC package, each delivering identical 20 ns propagation delay (tPLH/tPHL) under nominal conditions (25°C, VCC = 3.3 V). Its all-silicon architecture eliminates quartz aging and thermal drift issues inherent in analog delay solutions.
Delay accuracy is maintained over 0°C to 70°C and VCC = 2.7 V to 3.6 V, with total tolerance of ±1.5 ns over temperature/voltage at VCC = 3.3 V and ±2.5 ns at VCC = 2.7 V. Input-to-output symmetry preserves duty cycle integrity for both rising and falling edges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 20 ns - fixed, matched delay across IN1→OUT1, IN2→OUT2, IN3→OUT3 for skew-critical routing |
| Initial delay tolerance | ±1.5 ns - ensures tight batch-to-batch delay consistency without calibration |
| Supply voltage range | 2.7 V to 3.6 V - compatible with modern 3.3 V logic families and low-power embedded systems |
| Operating temperature | 0°C to 70°C - validated for commercial-grade industrial control and communications equipment |
| Output drive strength | IOL = 8 mA / IOH = –1 mA - sufficient to drive one 74F04-equivalent load per output |
| Rise/fall time | 2.0–3.5 ns - supports clean transitions on 500 ns minimum input pulse width |
| Input leakage current | ±1.0 µA - negligible loading on upstream drivers, enabling fan-out flexibility |
Pinout & Package
DS1033Z-20 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 notch or dot; substrate pins are internally connected and must remain unconnected externally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Input signal A | CMOS-compatible input driving first 20 ns delay path; accepts 0–3.3 V logic levels |
| 2 (IN2) | Input signal B | Independent second input; electrically isolated from IN1/IN3 for multi-channel timing |
| 3 (IN3) | Input signal C | Third independent input; enables simultaneous delay of three asynchronous signals |
| 4 (GND) | Ground reference | Primary return path for all internal circuitry; requires low-impedance PCB connection |
| 5 (VCC) | Power supply | +2.7 V to +3.6 V supply; bypass capacitor (0.1 µF) recommended adjacent to pin |
| 6 (OUT3) | Delayed output C | 20 ns delayed replica of IN3; matched edge timing preserves signal integrity |
| 7 (OUT1) | Delayed output A | 20 ns delayed replica of IN1; identical delay spec and edge precision as OUT2/OUT3 |
| 8 (OUT2) | Delayed output B | 20 ns delayed replica of IN2; fully buffered to prevent loading-induced delay shift |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates quartz-based aging, shock sensitivity, and thermal hysteresis found in crystal-based delay modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1033M-20 | Identical electrical specs; packaged in 8-pin DIP instead of SOIC | Preferred for through-hole prototyping or legacy board rework where SOIC footprint unavailable | Select DS1033M-20 only when DIP mounting or hand-soldering is required |
| MAX9622EUA+ | Single 20 ns delay path; higher drive (±24 mA); wider supply (2.7 V–5.5 V); different pinout | Suitable for single-line delay with stronger fan-out or mixed-voltage systems; not 3-channel capable | Choose MAX9622EUA+ only when single-output, higher-current, or 5 V compatibility is mandatory |
Compared with DS1033Z-20, DS1033M-20 offers identical timing performance in a through-hole package, while MAX9622EUA+ trades channel count for higher drive strength and broader voltage support-neither is pin-compatible, but both serve distinct layout or system-level constraints.

Manufacturer
Dallas Semiconductor, acquired by Maxim Integrated in 2001, specialized in precision analog, timing, and secure memory ICs for industrial and communications infrastructure.
The DS1033 series was designed specifically for nanosecond-accurate, multi-channel digital delay in commercial-grade embedded systems where quartz-based solutions were impractical due to size, cost, or reliability constraints.
FAQ
What is the guaranteed delay accuracy of DS1033Z-20 over its full operating temperature range?
The DS1033Z-20 guarantees ±2.5 ns total delay tolerance over 0°C to 70°C at VCC = 2.7 V, and ±1.5 ns at VCC = 3.3 V. This includes both initial tolerance (±1.5 ns) and additional variation due to temperature and supply voltage. Measurements are referenced to the 1.5 V switching threshold on both input and output edges, ensuring consistent interpretation across logic families.
Can DS1033Z-20 be used with 5 V logic inputs?
No-DS1033Z-20 is specified only for 2.7 V to 3.6 V operation and has VIH = 2.0 V (min) and VIL = 0.8 V (max). Applying 5 V inputs exceeds absolute maximum ratings and risks permanent damage. For 5 V systems, level-shifting circuitry or a 5 V–compatible alternative like the MAX9622EUA+ must be used alongside DS1033Z-20.
Are the three delay paths in DS1033Z-20 truly independent and isolated?
Yes-the DS1033Z-20 integrates three fully independent CMOS delay chains with separate input buffers and output drivers. Crosstalk between channels is suppressed to <10 ps via physical layout isolation and buffered outputs, and each path maintains its 20 ns delay regardless of activity on other inputs. This independence is verified in the device's logic diagram and AC characterization.
Does DS1033Z-20 require external passive components for stable operation?
DS1033Z-20 requires only a 0.1 µF ceramic bypass capacitor between VCC and GND, placed as close as possible to pins 5 and 4. No pull-up/down resistors, termination networks, or timing-setting components are needed-the 20 ns delay is factory-trimmed and fixed. The device draws ≤25 mA active current, minimizing thermal impact on nearby analog circuits.
Is DS1033Z-20 RoHS compliant and lead-free?
Yes-DS1033Z-20 is manufactured in a lead-free SOIC package compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1. It supports standard Pb-free reflow profiles (peak 260°C for 10 seconds), and its marking "Z" suffix explicitly denotes lead-free packaging per Maxim Integrated's product coding convention.
