Product details
Overview
DS1040Z-75+ from Maxim Integrated (formerly Dallas Semiconductor) is a rising-edge-triggered, CMOS programmable one-shot pulse generator with five selectable pulse widths, nominal 75 ns maximum width (±5% or ±2 ns), TTL/CMOS-compatible outputs, and dual non-inverted/inverted outputs for laser power control in magneto-optical disk read/write systems.
For engineers reviewing the DS1040Z-75+ datasheet, DS1040Z-75+ pinout, DS1040Z-75+ application, or DS1040Z-75+ equivalent, key selection factors include intrinsic delay ≤10 ns, output drive capability of five 74LS loads, 8-pin SOIC (150-mil) package, 5V supply operation, and precise width tolerance specification per programming code P2–P0.
Technical Context
The DS1040Z-75+ implements a parallel-programmed, edge-triggered monostable multivibrator using all-silicon CMOS logic. Pulse width is determined solely by the logic states of three binary input pins (P2, P1, P0), with no external timing components required.
It delivers both true and complemented outputs simultaneously, supports 5 ns minimum input pulse width, and guarantees intrinsic propagation delay ≤10 ns from IN to either OUT terminal under VCC = 5.0 V ±5% and TA = 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Pulse Width | 75 ns - fixed maximum width for DS1040Z-75+, selected via P2/P1/P0 coding |
| Width Tolerance | ±5% or ±2 ns, whichever is greater - ensures timing predictability across voltage/temperature |
| Intrinsic Delay | ≤10 ns - time from IN rising edge to OUT rising edge; enables tight system synchronization |
| Supply Voltage | 4.75 V to 5.25 V - compatible with standard 5V TTL/CMOS logic rails |
| Output Drive | 5 × 74LS loads - sufficient fanout for direct interface to legacy logic families |
| Input Pulse Width | ≥5 ns - minimum trigger pulse duration for reliable one-shot activation |
| Operating Temp | 0°C to +70°C - commercial-grade temperature range for embedded industrial use |
Pinout & Package
DS1040Z-75+ is housed in an 8-pin SOIC package (150-mil width), surface-mount compatible with vapor phase, IR, and wave soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Trigger Input | Rising-edge-sensitive digital input; initiates pulse generation on active transition |
| P2, P1, P0 | Width Programming Inputs | 3-bit parallel code selects one of five pulse widths (e.g., 000 = 75 ns max for DS1040Z-75+) |
| GND | Ground Reference | Logic and power return path; must be low-impedance for timing stability |
| OUT | Non-inverted Output | Active-high pulse synchronized to IN; drives downstream logic or laser modulation circuitry |
| OUT | Inverted Output | Complementary pulse to OUT; enables differential signaling or dual-gate control without external inverters |
| VCC | Positive Supply | +5 V DC power rail; decoupling capacitor required near pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon CMOS construction | Eliminates hybrid packaging reliability risks and enables auto-insertion and reflow compatibility |
| Dual true/complement outputs | Reduces external component count in push-pull or differential laser driver topologies |
| Programmable width selection | Enables single BOM part to support multiple timing requirements via PCB trace configuration |
| Low-power operation | ICC ≤75 mA at max frequency and VCC = 5.25 V - suitable for thermally constrained optical modules |
| Stable width tolerance | 5% or 2 ns accuracy maintained over full operating temperature and supply range |

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-75+ | Same electrical specs and programming; packaged in 8-pin DIP (300-mil) instead of SOIC | Through-hole assembly only; not suitable for SMT production or space-constrained optical modules | Select DS1040M-75+ only for prototyping or legacy through-hole designs requiring manual soldering |
| MC100EP131DG | Difference: ECL-based, 3.3V supply, faster min width (2.5 ns), no internal width programming - requires external delay line | Used in high-speed telecom clock recovery, not laser control; lacks integrated width selection logic | Choose MC100EP131DG only when sub-5 ns precision and ECL interfacing are mandatory; not drop-in compatible |
Compared with DS1040M-75+ and MC100EP131DG, the DS1040Z-75+ uniquely combines SOIC packaging, 5V operation, on-chip width programming, and guaranteed 75 ns width tolerance - making it optimal for cost-sensitive, SMT-based magneto-optical subsystems where layout simplicity and timing repeatability are prioritized.

FAQ
What is the exact pulse width behavior of DS1040Z-75+ for each P2/P1/P0 code?
The DS1040Z-75+ provides five discrete pulse widths determined by its three programming pins. For this variant, the maximum width is fixed at 75 ns; Table 1 in the datasheet shows corresponding widths per code (e.g., P2P1P0 = 000 yields 75 ns, 001 yields 60 ns, etc.). All widths maintain ±5% or ±2 ns tolerance, whichever is greater, across temperature and supply voltage.
Does DS1040Z-75+ require external components to operate?
No, DS1040Z-75+ operates as a fully self-contained one-shot: no external resistors or capacitors are needed for timing. Only a 0.1 µF ceramic decoupling capacitor between VCC and GND is recommended. The pulse width is set entirely by the logic states of P2, P1, and P0 - eliminating timing drift from component aging or temperature coefficients.
Can DS1040Z-75+ drive a laser diode directly?
No, DS1040Z-75+ cannot drive a laser diode directly. Its outputs are logic-level (5V CMOS/TTL), rated for 5 × 74LS loads (≈8 mA sink, −1 mA source). It must interface with a dedicated laser driver IC or MOSFET gate driver stage. Its role is precise timing control-not power delivery-making DS1040Z-75+ ideal for enabling that driver with nanosecond accuracy.
What is the meaning of "Z" in DS1040Z-75+?
The "Z" suffix in DS1040Z-75+ denotes the 8-pin SOIC (150-mil) package variant. This distinguishes it from the "M" suffix (8-pin DIP, 300-mil) and "T" suffix (TSSOP). The "+" indicates tape-and-reel packaging with full Maxim/Analog Devices traceability and extended temperature screening per datasheet specifications.
Is DS1040Z-75+ compatible with 3.3V logic systems?
DS1040Z-75+ is specified for 4.75 V to 5.25 V operation and is not 3.3V-tolerant. Its VIH minimum is 2.2 V, but VCC must be 5V. Interfacing with 3.3V controllers requires level translation on the IN and P2/P1/P0 lines. Outputs swing rail-to-rail (0–5V), so downstream 3.3V receivers need protection or translation to avoid overvoltage damage.
