Analog Devices Inc./Maxim Integrated DS1010-200

Overview

DS1010-200 from Dallas Semiconductor is a 10-tap all-silicon delay line with nominal total delay of 200 ns, ±5% or ±2 ns tolerance, TTL/CMOS-compatible input/output, 5 V supply, and capable of driving 10 × 74LS loads per tap - used in digital timing alignment, clock skew correction, and pulse width adjustment in test instrumentation and logic interface circuits.

For engineers reviewing the DS1010-200 datasheet, DS1010-200 pinout, DS1010-200 application, or DS1010-200 equivalent, key selection considerations include tap-to-tap uniformity (20 ns spacing), leading/trailing edge matching accuracy, 14-pin DIP or 16-pin SOIC package options, temperature-stable delay drift (±2 ns or ±3% over 0°C–70°C), and compatibility with legacy hybrid delay line footprints.

Technical Context

The DS1010-200 implements a monolithic CMOS tapped delay chain where each of ten outputs delivers a fixed incremental delay (20 ns/tap) referenced to the IN signal's rising and falling edges. Delay accuracy is specified at ±5% or ±2 ns (whichever greater) at 25°C, with additional temperature-induced shift of ±2 ns or ±3% for TAP 10 delays ≥100 ns.

It operates from a single 5.0 V ±5% supply, draws 40–150 mA active current, supports 40 ns minimum input pulse width, and maintains consistent unidirectional delay variation across all taps under voltage or temperature change - ensuring monotonic tap ordering without inversion or crossover.

Key Specifications

Pinout & Package

DS1010-200 is available in two packages: 14-pin DIP (300-mil) and 16-pin SOIC (300-mil). The DIP variant uses pins 1–14 with IN on pin 1, VCC on pin 14, GND on pin 7, and TAP 1–10 distributed across remaining pins; the SOIC variant uses pins 1–16 with IN on pin 1, VCC on pin 16, GND on pin 8, and TAPs assigned to pins 3–6, 9–13, plus two NC pins.

Compared with MC100EP195 and IXDD614, DS1010-200 offers lowest BOM cost, zero configuration overhead, and guaranteed 5 V TTL interoperability - making it optimal for static, production-volume timing alignment where nanosecond-level repeatability suffices.

Availability

DS1010-200 is available at Aetrix Electronics and suitable for digital test equipment, logic interface timing, pulse width modulation, and legacy system upgrades requiring stable component supply and long-term obsolescence management.

Supply support for DS1010-200 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

Dallas Semiconductor (now part of Maxim Integrated, then Analog Devices) specialized in precision timing, memory, and mixed-signal interface ICs for industrial and communications applications.

The DS1010 series was designed as a cost-effective, reliable silicon replacement for aging hybrid delay lines - targeting applications needing deterministic, multi-tap fixed delays in 5 V digital systems.

FAQ

What is the total delay and tap spacing for DS1010-200?

The DS1010-200 provides a total delay of 200 ns at TAP 10, with uniform 20 ns spacing between consecutive taps (TAP 1 = 20 ns, TAP 2 = 40 ns, ..., TAP 10 = 200 ns). This fixed increment is factory-trimmed and guaranteed across operating conditions, enabling predictable timing alignment without calibration.

Does DS1010-200 support both rising and falling edge delays?

Yes, DS1010-200 guarantees matched delay for both signal edges: tPLH (rising edge) and tPHL (falling edge) are identical within ±2 ns or ±5%, whichever is greater. This symmetry preserves pulse width and duty cycle - critical for applications like dead-time generation and clock deskewing.

What package options are available for DS1010-200?

DS1010-200 is offered in two standard packages: 14-pin DIP (300-mil) and 16-pin SOIC (300-mil). The DIP version is pin-compatible with legacy hybrid delay lines; the SOIC version reduces PCB area and supports surface-mount assembly. Both share identical electrical specifications and timing behavior.

Can DS1010-200 drive modern CMOS loads directly?

DS1010-200 is rated to drive up to 10 × 74LS loads per tap, which corresponds to ~1.6 mA sink/source capability. While compatible with older TTL and LSTTL, direct interfacing with modern low-threshold CMOS (e.g., 74HC, 74AHC) may require verification of VIH/VIL margins; level-shifting is recommended for 3.3 V systems.

What is the operating temperature range for DS1010-200?

DS1010-200 is specified for commercial operation from 0°C to 70°C. Delay accuracy degrades slightly outside 25°C: for TAP 10 delays ≥100 ns (including DS1010-200), additional shift of ±2 ns or ±3% occurs across this full range - a known, bounded effect documented in the datasheet.
