Analog Devices Inc./Maxim Integrated DS1040Z-150+

Overview

DS1040Z-150+ from Maxim Integrated (formerly Dallas Semiconductor) is a CMOS programmable one-shot pulse generator with five precise, user-selectable pulse widths ranging from 30 ns to 150 ns, rising-edge-triggered operation, TTL/CMOS-compatible I/O, and dual non-inverted/inverted outputs - used in magneto-optical laser power control and precision timing circuits.

For engineers reviewing the DS1040Z-150+ datasheet, DS1040Z-150+ pinout, DS1040Z-150+ application, or DS1040Z-150+ equivalent, key selection criteria include programmable width accuracy (±5% or ±2 ns), intrinsic delay ≤10 ns, output drive capability (5 × 74LS loads), and SOIC-8 packaging for surface-mount reliability in high-speed digital systems.

Technical Context

The DS1040Z-150+ implements a parallel-programmed monostable multivibrator using all-silicon CMOS logic, where P0–P2 programming pins select one of eight possible width configurations per Table 1 - for this variant, maximum width is 150 ns with minimum width 30 ns and increments of 30 ns (30/60/90/120/150 ns). It features separate OUT and OUT̅ outputs with matched propagation paths.

Timing is referenced to the 1.5 V threshold level on both input and output edges; intrinsic delay (t_D) is specified at 0–10 ns over temperature (0°C to 70°C), and power-up stabilization requires ≤100 ms before width specifications are valid. Input pulse width must exceed 5 ns at both logic high and low states.

FAQ

What is the maximum pulse width supported by DS1040Z-150+?

The DS1040Z-150+ supports a maximum pulse width of 150 ns, with five selectable widths (30 ns, 60 ns, 90 ns, 120 ns, and 150 ns) determined by the logic states of P0–P2 programming pins. This value is guaranteed across 0°C to 70°C and ±5% VCC, with accuracy specified as ±5% or ±2 ns, whichever is greater. The DS1040Z-150+ achieves this via all-silicon CMOS design, eliminating RC drift found in discrete alternatives.

Does DS1040Z-150+ require external components for basic operation?

No, DS1040Z-150+ operates autonomously with only a 0.1 µF ceramic bypass capacitor between VCC and GND. No external resistors or capacitors are needed to set pulse width - selection is fully digital via P0–P2. Input trigger conditioning (e.g., Schmitt trigger) is optional but recommended for noisy environments. The DS1040Z-150+ integrates all timing elements on-die, enabling drop-in replacement of RC-based one-shots.

What is the intrinsic delay of DS1040Z-150+ and how is it measured?

The intrinsic delay (t_D) of DS1040Z-150+ is 0–10 ns, defined as the time between the 1.5 V point on the rising edge of the IN trigger and the 1.5 V point on the rising edge of the OUT pulse. This parameter is measured under controlled conditions (25°C, VCC = 5.0 V ±0.1 V, 50 Ω source) using time-interval analyzers with 20 ps resolution. The DS1040Z-150+ maintains this delay bound across its full operating temperature and supply range.

Can DS1040Z-150+ drive standard TTL loads directly?

Yes, DS1040Z-150+ can drive up to five 74LS loads per output (OUT or OUT̅) without external buffering. Its I_OL = 8 mA (min) and I_OH = –1 mA (min) at VCC = 4.75 V meet 74LS input current requirements. The DS1040Z-150+ output stages are designed for TTL/CMOS compatibility, with V_OH ≥ 4.0 V and V_OL ≤ 0.5 V under load, ensuring reliable interfacing with legacy logic families.

Is DS1040Z-150+ pin-compatible with other DS1040 variants?

Yes, DS1040Z-150+ shares identical pinout and electrical behavior with all DS1040Z-x variants (e.g., DS1040Z-100+, DS1040Z-200+) in the same mini-SOIC-8 package. Programming pins P0–P2 retain the same binary-weighted function across the family, and all share identical timing architecture, supply, and output characteristics. The DS1040Z-150+ differs only in factory-trimmed internal timing elements to achieve its specific 30–150 ns width range.
