Analog Devices Inc./Maxim Integrated DS1040Z-200+

Overview

DS1040Z-200+ from Maxim Integrated (formerly Dallas Semiconductor) is a CMOS programmable one-shot pulse generator with five precise, user-selectable pulse widths ranging from 40 ns to 200 ns, rising-edge triggered, featuring both inverted and non-inverted outputs, and designed for laser power control in magneto-optical disk systems.

For engineers reviewing the DS1040Z-200+ datasheet, DS1040Z-200+ pinout, DS1040Z-200+ application, or DS1040Z-200+ equivalent, key selection considerations include pulse width accuracy (±5% or ±2 ns), intrinsic delay ≤10 ns, TTL/CMOS compatibility, dual-output capability, and SOIC-8 packaging for space-constrained timing control circuits.

Technical Context

The DS1040Z-200+ implements a parallel-programmed, all-silicon monostable multivibrator architecture where three logic inputs (P0–P2) select one of eight possible width configurations - four of which are active for the -200 variant, yielding max widths of 40 ns, 80 ns, 120 ns, and 200 ns. Width resolution depends on selected increment mode (equal or unequal).

It operates exclusively at VCC = 5.0 V ±5%, delivers output pulses referenced to 1.5 V thresholds, and guarantees timing stability across 0°C to 70°C with width variation ≤±3% or ±1 ns (whichever greater) over temperature. Intrinsic delay is measured between 1.5 V points on input trigger and output leading edge.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar programmable one-shot applications.

Compared with DS1040M-200+, the DS1040Z-200+ offers superior board density and thermal dissipation in automated SMT lines; versus MAX5072AESA+, it provides flexible width selection at the cost of fixed supply voltage and higher quiescent current.

Availability

DS1040Z-200+ is available at Aetrix Electronics and suitable for magneto-optical storage, industrial pulse gating, and test equipment signal conditioning requiring stable component supply and guaranteed pulse width repeatability.

Supply support for DS1040Z-200+ includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Maxim Integrated (acquired by Analog Devices in 2021) designs precision analog and mixed-signal ICs for industrial, communications, and computing markets.

The DS1040 series was developed by Dallas Semiconductor specifically for high-accuracy, low-jitter pulse generation in optical storage and instrumentation systems where RC-based timers lacked repeatability.

FAQ

What pulse widths does the DS1040Z-200+ support?

The DS1040Z-200+ supports four programmable pulse widths: 40 ns, 80 ns, 120 ns, and 200 ns - selected via the P0–P2 logic inputs. These correspond to the "max width" entries in Table 1 for part number DS1040-200. Minimum widths scale proportionally (e.g., 40 ns max → 40 ns min), and width tolerance remains ±5% or ±2 ns, whichever is greater.

Is the DS1040Z-200+ pin-compatible with other DS1040 variants?

Yes - the DS1040Z-200+ shares identical pinout and logic behavior with all DS1040Z (SOIC-8) variants, including DS1040Z-100+ and DS1040Z-500+. The only differences are internal trimming for specified width ranges; no PCB layout change is needed when substituting within the Z-package family.

Does the DS1040Z-200+ require external components to operate?

No external timing components are required. The DS1040Z-200+ is a fully self-contained pulse generator. A 0.1 µF ceramic bypass capacitor between VCC and GND is mandatory for stable operation, but no resistors or capacitors set pulse width - all timing is factory-trimmed and silicon-determined.

Can the DS1040Z-200+ drive MOSFET gates directly?

The DS1040Z-200+ outputs can drive up to five 74LS loads (≈20 mA sink/source), which is insufficient for direct high-side MOSFET gate driving. It is intended for logic-level interfacing; use a dedicated gate driver (e.g., TC4420) between DS1040Z-200+ and power MOSFETs to ensure fast turn-on/turn-off and voltage level translation.

What is the power-up timing requirement for the DS1040Z-200+?

The DS1040Z-200+ requires tPU = 100 ms after VCC reaches valid level before timing specifications are guaranteed. During this interval, outputs remain in high-impedance or undefined state. System designs must enforce a reset or inhibit signal until power-up timing completes to prevent spurious pulses.
