Product details
Overview
DS1040Z-D60 from Dallas Semiconductor (now Maxim Integrated) is a CMOS programmable one-shot pulse generator with rising-edge trigger, dual complementary outputs (OUT and OUT), and five precise pulse widths selectable via P0–P2 logic pins. Its nominal output pulse width is 60 ns (max), with tolerance ±5% or ±2 ns (whichever greater), intrinsic delay ≤10 ns, and TTL/CMOS-compatible I/O. It serves in laser power control for magneto-optical disk read/write systems.
For engineers reviewing the DS1040Z-D60 datasheet, DS1040Z-D60 pinout, DS1040Z-D60 application, or DS1040Z-D60 equivalent, key selection criteria include programmable width resolution (10 ns steps from 20–60 ns), dual-output drive capability (up to five 74LS loads), low-power CMOS operation at 5 V ±5%, and SOIC-8 packaging for surface-mount reliability.
Technical Context
The DS1040Z-D60 implements a parallel-programmed monostable multivibrator using all-silicon CMOS logic. Pulse width is determined solely by the static logic states of three programming inputs (P0, P1, P2), with no external timing components required. The device features separate non-inverting and inverting outputs driven from the same internal timing node.
It operates strictly on rising-edge triggering at the IN pin, with input pulse width ≥5 ns and intrinsic propagation delay ≤10 ns. Output pulse width accuracy is specified as ±5% or ±2 ns (whichever greater) over 0°C to +70°C, and power-up stabilization completes within 100 ms after VCC reaches valid level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Pulse Width (Max) | 60 ns - fixed maximum width for DS1040Z-D60 variant; minimum width 20 ns; step increments of 10 ns (20/30/40/50/60 ns) |
| Width Tolerance | ±5% or ±2 ns - worst-case deviation applies across temperature and supply; determines timing margin in precision laser gating |
| Intrinsic Delay (tD) | 0–10 ns - guaranteed max delay from IN rising edge to OUT rising edge; enables sub-10 ns system-level timing predictability |
| Supply Voltage (VCC) | 4.75 V to 5.25 V - tight 5% regulation required; active current ICC = 35–75 mA depending on width and frequency |
| Output Drive | 5 × 74LS loads - sufficient fanout for direct interface to legacy TTL logic without buffers in disk controller timing paths |
| Operating Temperature | 0°C to +70°C - commercial-grade range; width drift ≤ ±3% or ±1 ns over full range (per note 4) |
| Input Logic Thresholds | VIH ≥ 2.2 V, VIL ≤ 0.8 V - ensures robust compatibility with both 5 V TTL and CMOS signal sources |
Pinout & Package
DS1040Z-D60 is housed in an 8-pin SOIC package (150-mil width), RoHS-compliant, vapor-phase/wave-solderable, with gull-wing leads and standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Trigger Input | Rising-edge sensitive digital input; requires ≥5 ns high pulse width and fast edge (≤3 ns rise/fall); drives internal one-shot latch |
| P0, P1, P2 | Width Programming Inputs | 3-bit parallel select lines (LSB–MSB); logic state directly maps to one of five widths per Table 1 (000 = 20 ns, 100 = 60 ns) |
| GND | Ground Reference | Digital ground return for all internal logic and output drivers; must be low-impedance path to minimize timing jitter |
| OUT | Non-inverted Pulse Output | Active-high output pulse synchronized to IN rising edge; width and delay match OUT with polarity inversion |
| OUT | Inverted Pulse Output | Complementary active-low output; identical width/delay as OUT; enables differential timing or dual-gate control |
| VCC | Positive Supply | +5 V ±5% power rail; bypassing with 0.1 µF ceramic capacitor near pin is mandatory for stable pulse width accuracy |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon CMOS construction | Eliminates hybrid component failure modes; achieves >10× reliability vs. older RC-based one-shots in disk drive environments |
| Dual complementary outputs | Simultaneous OUT and OUT pulses enable single-device control of paired laser enable/disable or gate driver pairs without external inverters |
| Programmable width resolution | Five discrete widths (20/30/40/50/60 ns) with 10 ns step size-optimized for magneto-optical write-pulse shaping and servo timing windows |
| Low intrinsic delay variation | ≤10 ns max tD with <5 ns typical; supports tight synchronization between trigger and laser activation in high-speed data channels |
| Auto-insertable SOIC packaging | 150-mil SOIC-8 footprint allows automated SMT assembly; compatible with IR, vapor phase, and wave solder processes without lead damage |

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-D60 | Same electrical specs and programming logic, but in 300-mil 8-pin DIP package instead of SOIC | Used in through-hole prototyping or legacy PCBs lacking SMT capability; higher profile and larger footprint | Select DS1040M-D60 only when DIP mounting or hand-soldering is required; otherwise DS1040Z-D60 preferred for density and manufacturability |
| MAX1040Z-D60 | No functional difference; rebranded part post-Maxim acquisition of Dallas Semiconductor; identical datasheet, marking, and qualification | No application impact; used interchangeably in new designs and BOM updates where Maxim branding is specified | MAX1040Z-D60 is a direct lineage replacement; no design change needed-same pinout, timing, and thermal behavior |

FAQ
What is the exact pulse width range supported by DS1040Z-D60?
The DS1040Z-D60 provides five fixed pulse widths: 20 ns, 30 ns, 40 ns, 50 ns, and 60 ns (maximum). These are selected via the P0–P2 programming pins per Table 1 in the datasheet. Unlike broader-family variants, DS1040Z-D60 does not support widths outside this set-its part number explicitly denotes the 60 ns max configuration.
Does DS1040Z-D60 require external timing components like resistors or capacitors?
No. The DS1040Z-D60 is an all-silicon CMOS one-shot with fully internal timing generation. No external R/C networks are needed-pulse width is determined exclusively by the logic states of P0, P1, and P2. Only a 0.1 µF VCC bypass capacitor is required for stable operation.
Can DS1040Z-D60 drive standard TTL loads directly?
Yes. Each output (OUT and OUT) of the DS1040Z-D60 can drive up to five 74LS loads, meeting standard TTL voltage and current thresholds (VOH ≥ 4 V, VOL ≤ 0.5 V, IOL = 8 mA). This allows direct interfacing with legacy disk controller logic without level-shifting or buffering.
What is the maximum allowable input pulse width for reliable triggering of DS1040Z-D60?
The DS1040Z-D60 requires a minimum input pulse width (tWIH/tWIL) of 5 ns at logic high and logic low. There is no specified maximum-however, consecutive triggers spaced closer than tWO + 50 ns (e.g., <110 ns for DS1040Z-D60) may cause metastability or missed pulses due to internal reset timing constraints.
Is DS1040Z-D60 compatible with modern 3.3 V logic systems?
No. The DS1040Z-D60 is strictly a 5 V device: VCC must be 4.75–5.25 V, VIH ≥ 2.2 V, and it lacks 3.3 V tolerant inputs. Interfacing with 3.3 V microcontrollers requires level translation on IN and interpretation of OUT/OUT signals-direct connection risks unreliable triggering or excessive input leakage.
