Product details
Overview
DS1040Z-100+ from Maxim Integrated (formerly Dallas Semiconductor) is a rising-edge-triggered, CMOS programmable one-shot pulse generator with five selectable pulse widths ranging from 20 ns to 100 ns, ±5% or ±2 ns accuracy, TTL/CMOS-compatible outputs, and dual non-inverted/inverted outputs - used in magneto-optical laser power control and precision timing circuits.
For engineers reviewing the DS1040Z-100+ datasheet, DS1040Z-100+ pinout, DS1040Z-100+ application, or DS1040Z-100+ equivalent, key selection criteria include intrinsic delay ≤10 ns, output drive capability of five 74LS loads, 8-pin SOIC package compatibility, and precise width programming via P0–P2 logic states.
Technical Context
The DS1040Z-100+ implements a fully silicon-based monostable multivibrator architecture with parallel 3-bit width selection (P2/P1/P0), generating fixed-duration pulses upon each rising edge of the IN signal. It delivers both true and complement outputs simultaneously with no additional external logic.
Its timing accuracy is specified at ±5% or ±2 ns (whichever is greater) over 0°C to +70°C, with intrinsic propagation delay bounded at 0–10 ns and guaranteed minimum input pulse width of 5 ns. Power-up stabilization requires ≤100 ms before timing specs are valid.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Pulse Width | 100 ns - sets upper bound for laser gate duration or signal strobe timing |
| Width Accuracy | ±5% or ±2 ns - determines timing margin in closed-loop optical control systems |
| Intrinsic Delay | 0–10 ns - defines minimum latency between trigger and output activation |
| Output Drive | 5 × 74LS loads - supports direct fanout to legacy TTL logic without buffers |
| Supply Voltage | 4.75 V to 5.25 V - compatible with standard 5 V digital rails and noise margins |
| Operating Temp | 0°C to +70°C - suitable for commercial-grade embedded timing applications |
| Input Logic | Rising-edge triggered - eliminates false triggering from noise on falling edges |
Pinout & Package
DS1040Z-100+ is housed in an 8-pin 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-time and 5 ns low-time |
| P0, P1, P2 | Width Programming Inputs | 3-bit parallel code selects one of five pulse widths (e.g., 000 = 20 ns, 100 = 100 ns) |
| GND | Ground Reference | Return path for all internal logic and output drivers |
| OUT | Non-inverted Output | Active-high pulse synchronized to IN rising edge; drives 5 × 74LS |
| OUT | Inverted Output | Complementary active-low pulse; enables differential timing or enable/disable pairing |
| VCC | Power Supply | +5 V supply with 4.75–5.25 V tolerance; decoupling recommended near pin |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid packaging reliability risks and enables auto-insertion |
| Dual true/complement outputs | Enables simultaneous enable and disable signaling without external inverters |
| Programmable width selection | Three logic pins (P0–P2) configure pulse width in-system without rework |
| Low-power CMOS design | ICC ≤ 35 mA typical at max frequency - reduces thermal load in dense PCB layouts |
| TTL/CMOS compatibility | VIH ≥ 2.2 V and VIL ≤ 0.8 V - interoperable with mixed-logic families |

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-100+ | Same electrical specs; 8-pin DIP (300-mil) through-hole package instead of SOIC | Preferred for prototyping, manual assembly, or legacy board rework where SMT is unavailable | Select DS1040M-100+ when through-hole mounting or socket-based validation is required |
| MAX7360EPA+ | Single-channel, fixed 100 ns width; no programming pins; 8-pin PDIP only; higher ICC (100 mA) | Limited to static-width use cases; lacks P0–P2 flexibility and dual outputs | Choose MAX7360EPA+ only if width immutability and legacy DIP footprint are mandatory |
Compared with DS1040Z-100+, DS1040M-100+ offers identical timing behavior in a through-hole format, while MAX7360EPA+ sacrifices programmability and output polarity flexibility for simplified fixed-width operation - making DS1040Z-100+ optimal for field-configurable or space-constrained SMT designs.

FAQ
What is the guaranteed pulse width accuracy of DS1040Z-100+ across temperature?
The DS1040Z-100+ guarantees pulse width accuracy of ±5% or ±2 ns, whichever is greater, over its full operating temperature range of 0°C to +70°C. At 25°C, typical accuracy improves to ±2 ns absolute. Temperature variation adds up to ±1 ns or ±3% beyond the base tolerance, depending on width setting - confirmed in the AC Electrical Characteristics table and Notes 4–5 of the datasheet.
Does DS1040Z-100+ require external components to operate?
No, DS1040Z-100+ operates as a self-contained pulse generator with no external timing components required. Only a 0.1 µF ceramic decoupling capacitor between VCC and GND is recommended near the package. All timing is determined internally by silicon process and P0–P2 programming inputs - no resistors, capacitors, or crystals are needed for basic functionality.
Can DS1040Z-100+ drive modern CMOS loads like 74LVC or 74AUC?
Yes, DS1040Z-100+ can drive 74LVC and 74AUC families, though its output specifications are characterized for 74LS loads (IOL = 8 mA, IOH = –1 mA). With VOH ≥ 4.0 V and VOL ≤ 0.5 V under load, it meets 74LVC input thresholds. For high-speed or high-fanout 74AUC designs, verify signal integrity using the 10 pF typical input capacitance and 10 ns intrinsic delay.
What is the minimum input pulse width required to trigger DS1040Z-100+ reliably?
The DS1040Z-100+ requires a minimum input pulse width of 5 ns at both logic high (tWIH) and logic low (tWIL) to ensure reliable triggering. This is specified in the AC Electrical Characteristics table. Pulses shorter than 5 ns may fail to register or produce inconsistent output widths due to internal setup/hold timing constraints.
Is DS1040Z-100+ RoHS compliant and lead-free?
Yes, DS1040Z-100+ is RoHS compliant and lead-free. The "+" suffix in the part number denotes lead-free, halogen-free, and RoHS-compliant packaging per Maxim Integrated's product marking convention. The SOIC package uses matte tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1).
