Analog Devices Inc./Maxim Integrated DS1013S-50

Overview

DS1013S-50 from Dallas Semiconductor (now Maxim Integrated) is a 3-channel all-silicon logic delay line in 16-pin SOIC package, delivering precisely matched 50 ns ±2 ns propagation delay on all three outputs (tPLH/tPHL), TTL/CMOS-compatible input/output levels, and operation over 0°C to 70°C. It serves as a compact, low-power replacement for hybrid delay lines in digital timing alignment, clock deskewing, and pulse width adjustment circuits.

For engineers reviewing the DS1013S-50 datasheet, DS1013S-50 pinout, DS1013S-50 application, or DS1013S-50 equivalent, key selection criteria include guaranteed edge-matched delay tolerance, 10 LS-load drive capability per output, 5V ±5% supply operation, and compatibility with wave/IR/vapor-phase soldering processes.

Technical Context

The DS1013S-50 implements three independent buffered delay paths within a single monolithic CMOS IC, each reproducing both rising and falling edges with equal precision (tPLH = tPHL = 50 ns). Delay accuracy is maintained across voltage (4.75–5.25 V) and temperature (0–70°C) variations, with unidirectional delay drift ensuring consistent channel-to-channel skew.

No internal PLL or feedback loop is used; delay is fixed and passive in nature-achieved via calibrated gate-chain propagation. Input pulse width must exceed 100% of tPLH (≥50 ns), and outputs are specified at 1.5 V switching threshold under 74F04-equivalent load conditions.

Supply support for DS1013S-50 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

Dallas Semiconductor, now part of Maxim Integrated (analog/mixed-signal subsidiary of Analog Devices), specializes in precision timing, memory, and security ICs for industrial and communications infrastructure.

The DS1013 series was designed specifically to replace aging hybrid delay lines in commercial digital systems-delivering silicon-based reliability, auto-insertability, and tight delay matching without custom calibration.

FAQ

What is the exact delay value and tolerance of DS1013S-50?

The DS1013S-50 provides a nominal delay of 50 ns on all three outputs (tPLH and tPHL), with a guaranteed tolerance of ±2 ns over the full operating temperature range (0°C to 70°C) and supply voltage (4.75 V to 5.25 V). This applies to both rising and falling edges, ensuring edge-matched performance critical for timing-critical digital systems.

Does DS1013S-50 require external components for basic operation?

No, the DS1013S-50 operates stand-alone with only a 0.1 µF ceramic decoupling capacitor placed near the VCC pin (pin 14) and proper grounding at pin 7. No resistors, capacitors, or configuration pins are needed-its 50 ns delay is factory-trimmed and fixed, eliminating tuning or calibration overhead in the DS1013S-50 design-in process.

Can DS1013S-50 drive standard TTL loads directly?

Yes, each output of the DS1013S-50 can drive up to 10 × 74LS loads (12 mA sink, –1 mA source), meeting standard TTL fan-out requirements without external buffers. The DS1013S-50 maintains specified delay accuracy under this load condition, verified per test conditions in the official datasheet.

Is DS1013S-50 compatible with lead-free reflow processes?

Yes, the DS1013S-50 is qualified for lead-free surface-mount assembly and supports vapor-phase, infrared (IR), and wave soldering per JEDEC J-STD-020. Its 16-pin SOIC package meets RoHS requirements and withstands peak reflow temperatures up to 260°C for 10 seconds, as confirmed in the absolute maximum ratings table for DS1013S-50.

How does DS1013S-50 handle input pulse width and rise/fall time constraints?

The DS1013S-50 requires input pulse width ≥50 ns (100% of tPLH) and input rise/fall times ≤3.0 ns to maintain specified delay accuracy. These constraints ensure reliable triggering and prevent metastability; violating them may cause delay variation beyond ±2 ns or output pulse distortion in the DS1013S-50.
