Product details
Overview
DS1040Z-A15+ from Maxim Integrated (formerly Dallas Semiconductor) is a rising-edge-triggered, CMOS programmable one-shot pulse generator with five precise pulse widths, 5 ns minimum output width, ±5% or ±2 ns width tolerance, and dual inverting/non-inverting outputs. It serves as a timing control element in laser power modulation for magneto-optical disk read/write systems.
For engineers reviewing the DS1040Z-A15+ datasheet, DS1040Z-A15+ pinout, DS1040Z-A15+ application, or DS1040Z-A15+ equivalent, key selection criteria include guaranteed 15 ns maximum pulse width, intrinsic delay ≤10 ns, TTL/CMOS compatibility, 8-pin SOIC (150-mil) package, and operation across 0°C to 70°C.
Technical Context
The DS1040Z-A15+ implements a parallel-programmed, single-shot monostable multivibrator architecture using all-silicon CMOS logic. Pulse width is selected via three binary-coded programming pins (P0–P2), with the A15 variant fixed to a maximum width of 15 ns and minimum width of 5 ns.
It features dual complementary outputs capable of driving up to five 74LS loads each, intrinsic delay ≤10 ns referenced to the 1.5 V threshold, and operates from a single +5.0 V ±5% supply. Width accuracy is specified as ±5% or ±2 ns (whichever is greater) at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Pulse Width | 15 ns - defines longest controllable on-time for laser gating or signal strobing |
| Min Pulse Width | 5 ns - enables ultra-fast transient control in high-speed optical switching |
| Width Tolerance | ±5% or ±2 ns - ensures timing predictability without calibration in production systems |
| Intrinsic Delay | ≤10 ns - guarantees sub-15 ns total latency from trigger edge to output edge |
| Supply Voltage | +5.0 V ±5% - compatible with standard TTL/CMOS logic rails and eliminates need for LDO regulation |
| Output Drive | 5 × 74LS loads - supports direct interfacing to legacy logic without buffer amplification |
| Operating Temp | 0°C to +70°C - suitable for commercial-grade embedded instrumentation and optical drive controllers |
Pinout & Package
DS1040Z-A15+ is housed in an 8-pin SOIC package with 150-mil body width and standard gull-wing lead form. Pin 1 is marked by a notch or dot; leads are RoHS-compliant and vapor-phase/wave-solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Trigger Input | Rising-edge sensitive input; requires ≥5 ns logic-high pulse width and ≤3 ns rise/fall time |
| P0, P1, P2 | Width Programming Inputs | Binary-coded selection of one of five pulse widths (000 = 5 ns, 111 = 15 ns) |
| GND | Ground Reference | Primary return path for supply and signal currents; must be low-impedance |
| OUT | Non-inverted Output | Active-high pulse synchronized to IN rising edge; drives 5 × 74LS loads |
| OUT | Inverted Output | Complementary active-low pulse; enables differential signaling or dual-gate control |
| VCC | Power Supply | +5.0 V ±5% input; decoupling capacitor (0.1 µF) required within 10 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid packaging drift and improves long-term pulse width stability over temperature |
| Programmable width selection | Three parallel pins (P0–P2) allow factory or board-level configuration without external components |
| Dual complementary outputs | Simultaneous non-inverted and inverted pulses reduce need for external inverters in gate-drive circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable one-shot applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1040Z-A20+ | 20 ns maximum width; same 8-pin SOIC package, identical pinout and timing architecture | Suitable where slightly longer pulse width is acceptable for reduced timing margin risk | Select when system timing budget allows ≥20 ns enable duration and higher width tolerance is acceptable |

FAQ
What is the guaranteed maximum pulse width for DS1040Z-A15+?
The DS1040Z-A15+ guarantees a maximum pulse width of 15 ns, with minimum width of 5 ns. This value is fixed by the A15 variant designation and confirmed in Table 1 of the datasheet. Width accuracy is ±5% or ±2 ns (whichever is greater) at 25°C, and DS1040Z-A15+ maintains this specification across its full 0°C to +70°C operating range.
Does DS1040Z-A15+ require external timing components like resistors or capacitors?
No, DS1040Z-A15+ is an all-silicon, fully integrated one-shot with no external RC timing network. Pulse width is set solely by the logic states of P0–P2 programming pins. This eliminates component variation, temperature drift, and PCB layout sensitivity associated with discrete timing elements-making DS1040Z-A15+ ideal for high-reliability optical subsystems.
Can DS1040Z-A15+ drive standard TTL loads directly?
Yes, DS1040Z-A15+ can drive up to five 74LS loads per output, meeting standard TTL voltage and current thresholds. Its outputs swing rail-to-rail (0 V to VCC) with IOL = 8 mA and IOH = –1 mA under worst-case conditions, ensuring robust noise margins and fanout capability without level-shifting or buffering-critical for integration into legacy logic-based optical controller designs.
What is the intrinsic propagation delay of DS1040Z-A15+?
The intrinsic delay (tD) of DS1040Z-A15+ is specified as 0 ns (minimum), 5 ns (typical), and 10 ns (maximum) from the 1.5 V point of the IN rising edge to the 1.5 V point of either OUT edge. This deterministic, sub-10 ns delay enables precise synchronization in laser gating applications where timing uncertainty must remain below 15 ns total.
Is DS1040Z-A15+ pin-compatible with other DS1040 variants in SOIC packages?
Yes, all DS1040Z-x variants-including DS1040Z-A15+, DS1040Z-A20+, and DS1040Z-75+-share identical 8-pin SOIC (150-mil) pinouts and electrical interfaces. The only functional difference is programmed pulse width range; no PCB redesign or layout change is required when substituting within the Z-series, enabling flexible prototyping and last-minute timing optimization.
