Product details
Overview
DS1040Z-500+ from Maxim Integrated (formerly Dallas Semiconductor) is a rising-edge-triggered, CMOS programmable one-shot pulse generator with five precise, user-selectable pulse widths up to 500 ns. It features dual complementary outputs (OUT and OUT), 5% or 2 ns width tolerance, intrinsic delay ≤10 ns, and drives up to five 74LS loads - used in magneto-optical laser power control and precision timing circuits.
For engineers reviewing the DS1040Z-500+ datasheet, DS1040Z-500+ pinout, DS1040Z-500+ application, or DS1040Z-500+ equivalent, key selection considerations include programmable width resolution (100 ns increments), TTL/CMOS compatibility, SOIC-8 package footprint, and guaranteed operation across 0°C to 70°C ambient.
Technical Context
The DS1040Z-500+ implements a parallel-programmed, all-silicon monostable multivibrator architecture with three logic inputs (P0–P2) selecting one of eight possible width configurations - for the -500 variant, five are active: 100 ns, 200 ns, 300 ns, 400 ns, and 500 ns max widths. Widths are stable over temperature with ±3% variation (0°C–70°C).
It operates at VCC = 4.75 V to 5.25 V, consumes 35–75 mA active current depending on frequency and width, and delivers both non-inverted and inverted outputs simultaneously with ≤10 ns intrinsic delay from IN to either output edge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Pulse Width | 500 ns - fixed upper limit for DS1040Z-500+, enabling precise laser gate timing in optical storage systems |
| Width Tolerance | ±5% or ±2 ns, whichever greater - ensures repeatable timing margins in closed-loop control loops |
| Intrinsic Delay | 0–10 ns - guarantees sub-10 ns response latency from trigger to output edge, critical for real-time signal conditioning |
| Output Drive | 5 × 74LS loads - supports direct interfacing with legacy TTL logic without buffer amplification |
| Supply Voltage | 4.75 V to 5.25 V - compatible with standard +5 V regulated rails and tolerant of typical board-level ripple |
| Operating Temp | 0°C to 70°C - validated for commercial-grade embedded systems including disk drive controllers and industrial I/O modules |
Pinout & Package
DS1040Z-500+ is housed in an 8-pin mini-SOIC (150-mil width) package, surface-mount compatible with vapor phase, IR, and wave soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Trigger Input | Rising-edge sensitive input; requires ≥5 ns high pulse width and <3 ns rise/fall time for reliable triggering |
| P0, P1, P2 | Width Programming Inputs | 3-bit parallel code selects one of five active widths (100–500 ns); LSB = P0, MSB = P2 |
| GND | Ground Reference | Return path for VCC and all internal logic; must be low-impedance to minimize timing jitter |
| OUT | Non-inverted Output | Active-high pulse matching programmed width; drives 74LS loads directly |
| OUT | Inverted Output | Complementary active-low pulse; enables differential signaling or dual-gate control without external inverters |
| VCC | Positive Supply | +5 V supply pin; bypass capacitor (0.1 µF) recommended near pin for noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| Dual complementary outputs | Simultaneous OUT and OUT eliminate need for external inverters in push-pull or enable/disable timing schemes |
| Programmable width resolution | 100 ns step increments (100/200/300/400/500 ns) provide coarse but deterministic timing granularity for system-level synchronization |
| Low intrinsic delay | ≤10 ns delay from IN to output edge enables tight trigger-to-action timing in feedback-critical applications like laser diode modulation |
| TTL/CMOS compatibility | VIH ≥2.2 V and VIL ≤0.8 V allow direct interface with both 5 V logic families without level-shifting circuitry |
| Auto-insertable SOIC package | 8-pin mini-SOIC (150-mil) supports automated assembly and offers 30% board area reduction vs. DIP variants |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable one-shot applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1040M-500+ | DIP-8 package instead of SOIC-8; identical electrical specs and pinout mapping | Suitable for through-hole prototyping or legacy PCBs requiring DIP footprint | Select DS1040M-500+ only when manual assembly or socket-based testing is required |
| MAX7360EPA+ | 8-pin SOIC, but programmable via I²C (not parallel pins); 10 ns to 100 ms range; higher quiescent current | Used where dynamic reconfiguration is needed, not fixed-width operation | Choose MAX7360EPA+ only if runtime width adjustment or multi-device synchronization is required |
Compared with DS1040M-500+ and MAX7360EPA+, the DS1040Z-500+ offers lowest-cost, simplest implementation for static 500 ns pulse generation in space-constrained SMT designs - no firmware, no serial bus, no external components beyond decoupling.

The DS1040 series was developed by Dallas Semiconductor - now part of Maxim - specifically for high-reliability, low-jitter pulse generation in optical storage, data acquisition, and industrial control systems where hybrid timing devices were previously used.
FAQ
What is the maximum guaranteed pulse width accuracy of DS1040Z-500+?
The DS1040Z-500+ guarantees pulse width accuracy of ±5% or ±2 ns, whichever is greater, over the full operating temperature range (0°C to 70°C). At 500 ns, this equates to ±25 ns or ±2 ns - so the tighter ±2 ns bound applies. This specification is confirmed in the AC Electrical Characteristics table and verified under standard test conditions (VCC = 5.0 V ±0.1 V, TA = 25°C).
Does DS1040Z-500+ require external components to operate?
No, DS1040Z-500+ operates autonomously with only a 0.1 µF ceramic bypass capacitor between VCC and GND. No external resistors, capacitors, or clock sources are needed - programming is done via static logic levels on P0–P2, and triggering occurs on the rising edge of IN. The device draws power only during pulse generation, minimizing idle current.
Can DS1040Z-500+ be used with 3.3 V logic systems?
No, DS1040Z-500+ is specified only for VCC = 4.75 V to 5.25 V and requires TTL/CMOS-compatible input thresholds (VIH ≥2.2 V, VIL ≤0.8 V). It is not 3.3 V tolerant. Interfacing with 3.3 V microcontrollers requires a level shifter on IN and proper voltage translation for P0–P2 programming lines to avoid violating absolute maximum ratings.
What is the intrinsic delay of DS1040Z-500+ and how is it measured?
The intrinsic delay (tD) of DS1040Z-500+ is 0–10 ns, defined as the time between the 1.5 V point on the rising edge of the IN trigger and the 1.5 V point on the rising edge of either OUT or OUT. This parameter is measured using a time interval analyzer under standard test conditions (VCC = 5.0 V, TA = 25°C) and reflects worst-case propagation latency independent of programmed width.
Is DS1040Z-500+ RoHS compliant and lead-free?
Yes, DS1040Z-500+ is RoHS compliant and lead-free. The "+" suffix in the part number indicates compliance with EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 3 marking. The mini-SOIC package uses matte tin (Sn) lead finish and meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements.
