Product details
Overview
DS1040Z-A15 from Dallas Semiconductor (now Maxim Integrated) is a CMOS programmable one-shot pulse generator with rising-edge trigger, dual complementary outputs (OUT/OUT), and precisely selectable 15 ns maximum pulse width (5–15 ns increments). It delivers 5% or 2 ns width tolerance, <10 ns intrinsic delay, and drives up to five 74LS loads-used in laser power control 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 programmable sub-20 ns pulse widths, TTL/CMOS compatibility, SOIC-8 packaging, low-power operation, and guaranteed output drive capability under industrial temperature conditions.
Technical Context
The DS1040Z-A15 implements a parallel-programmed monostable multivibrator using all-silicon CMOS logic, where P0–P2 pins select one of eight discrete pulse widths (5, 7.5, 10, 12.5, 15, 15, 15, 15 ns). Its timing accuracy is specified at ±5% or ±2 ns (whichever greater) over 0°C to 70°C, with intrinsic delay bounded at 10 ns max.
It features dual rail-to-rail complementary outputs, operates from 4.75 V to 5.25 V, draws ≤75 mA active current at minimum period, and supports vapor-phase, IR, and wave soldering-enabling reliable integration into high-density PCBs without hybrid component compromises.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Pulse Width | 15 ns - sets upper bound for laser gating or timing window in precision optical control |
| Width Tolerance | ±5% or ±2 ns - ensures repeatable timing margins in closed-loop servo systems |
| Intrinsic Delay | 0–10 ns - enables sub-20 ns total system latency from trigger to output edge |
| Supply Voltage | 4.75 V to 5.25 V - compatible with standard +5 V TTL/CMOS logic rails |
| Output Drive | 5 × 74LS loads - sufficient fanout for direct interface to legacy logic or level-shifting buffers |
| Operating Temp | 0°C to +70°C - validated for commercial-grade embedded instrumentation and disk drive electronics |
| Logic Compatibility | TTL/CMOS - eliminates need for level translators in mixed-logic designs |
Pinout & Package
DS1040Z-A15 is housed in an 8-pin mini-SOIC package (150-mil width), surface-mount compatible with automated assembly and reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Trigger Input | Rising-edge sensitive input; requires ≥5 ns logic-high pulse width for reliable activation |
| P0, P1, P2 | Width Programming Inputs | 3-bit parallel code selecting one of eight pulse widths per Table 1 (e.g., 000 = 5 ns, 100 = 15 ns) |
| GND | Ground Reference | Return path for supply and signal currents; must be low-impedance for timing stability |
| OUT | Non-inverted Output | Active-high pulse synchronized to IN rising edge; drives 74LS-compatible loads |
| OUT | Inverted Output | Complementary active-low pulse; enables differential signaling or dual-gate control |
| VCC | +5 V Supply | Power rail; bypass capacitor (0.1 µF) required near pin for noise immunity |
Key Features

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-A15 | Same electrical specs; packaged in 8-pin DIP (300-mil) instead of SOIC | Preferred for through-hole prototyping or legacy board rework where SOIC footprint unavailable | Select DS1040M-A15 only when manual assembly or socket-based testing is required |
| MC14538BDR2G | CMOS dual monostable; fixed 100 ns min width; no programmable width selection; wider tolerance (±20%) | Suitable for non-critical timing where 15 ns precision is unnecessary | Choose MC14538BDR2G only if cost sensitivity outweighs width accuracy and programmability needs |
Compared with DS1040Z-A15, DS1040M-A15 offers identical timing performance in through-hole format, while MC14538BDR2G sacrifices programmability and precision for broader availability and lower unit cost-making DS1040Z-A15 the sole choice for sub-20 ns, factory-calibrated pulse generation.

FAQ
What is the exact pulse width range supported by DS1040Z-A15?
The DS1040Z-A15 supports five discrete pulse widths: 5 ns, 7.5 ns, 10 ns, 12.5 ns, and 15 ns-selected via P0–P2 programming pins. Its maximum width is 15 ns, and all widths maintain ±5% or ±2 ns tolerance, whichever is greater, across 0°C to +70°C operation.
Does DS1040Z-A15 require external components to operate?
No, DS1040Z-A15 operates autonomously with only a 0.1 µF bypass capacitor on VCC. It needs no external resistors or capacitors for timing-pulse width is fully determined by the logic states of P0–P2, and intrinsic delay is internally fixed at ≤10 ns.
Can DS1040Z-A15 drive modern logic families like 74LVC or 74AHC?
Yes, DS1040Z-A15 outputs are TTL/CMOS-compatible and rail-to-rail. While rated for 5 × 74LS loads, its VOH ≥4.0 V and VOL ≤0.5 V at VCC = 4.75 V meet 74LVC and 74AHC input thresholds, enabling direct interface without level shifters in most +5 V systems.
Is DS1040Z-A15 pin-compatible with other DS1040 variants?
Yes, all DS1040 variants-including DS1040Z-A15, DS1040Z-75, and DS1040M-A15-share identical 8-pin SOIC or DIP pinouts and logic-level behavior. Only the programmed pulse width differs; no PCB changes are needed when substituting within the same package type.
What is the power-up behavior of DS1040Z-A15?
DS1040Z-A15 requires ≤100 ms power-up time after VCC reaches valid level before timing specifications stabilize. During this interval, outputs remain in high-impedance or undefined state-designs must incorporate reset synchronization or blanking logic if trigger events occur immediately after power application.
