Analog Devices Inc./Maxim Integrated DS1010S-200

Overview

DS1010S-200 from Dallas Semiconductor (now Maxim Integrated) is a 10-tap all-silicon delay line with fixed 200 ns total delay (20 ns per tap), TTL/CMOS-compatible input, 5 V supply, ±5% or ±2 ns delay tolerance, and 16-pin SOIC package. It delivers precise leading and trailing edge timing for digital signal alignment in test instrumentation and logic synchronization circuits.

For engineers reviewing the DS1010S-200 datasheet, DS1010S-200 pinout, DS1010S-200 application, or DS1010S-200 equivalent, key selection factors include tap-to-tap uniformity, edge accuracy under temperature variation, drive capability (10 × 74LS loads), solder compatibility (vapor phase/IR/wave), and SOIC footprint reduction versus DIP alternatives.

Technical Context

The DS1010S-200 implements a monolithic CMOS delay chain with ten equally spaced taps, where each tap reproduces the input logic state after a cumulative fixed delay-TAP 1 at 20 ns, TAP 10 at 200 ns. Delay accuracy is specified as ±5% or ±2 ns (whichever greater) at 25°C, with additional temperature-induced shift of ±2 ns or ±3% over 0°C to 70°C for this 200 ns variant.

All outputs are buffered to drive up to ten 74LS-type loads, and both tPLH (rising edge) and tPHL (falling edge) delays are matched within specification. The device operates from 4.75 V to 5.25 V and exhibits unidirectional delay drift across taps under voltage or temperature change-ensuring monotonic tap ordering.

Key Specifications

Pinout & Package

DS1010S-200 uses a 16-pin SOIC (300-mil width) package with gull-wing leads, optimized for surface-mount assembly and reduced PCB area versus the 14-pin DIP variant.

Manufacturer

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

The DS1010 series was designed to replace hybrid delay lines with monolithic silicon solutions-delivering tighter delay tolerance, better temperature stability, and lower cost in test, measurement, and logic interface applications.

FAQ

What is the total propagation delay from input to TAP 10 on the DS1010S-200?

The DS1010S-200 provides a nominal total delay of 200 ns from the IN pin to the TAP 10 output, with a tolerance of ±5% or ±2 ns (whichever is greater). This value is fixed and factory-trimmed; it does not vary with load under specified conditions (10 × 74LS loads, VCC = 5.0 V, TA = 25°C). The DS1010S-200 achieves this via a monolithic CMOS delay chain with ten equally spaced taps.

Does the DS1010S-200 support both rising and falling edge delays with equal accuracy?

Yes, the DS1010S-200 is explicitly characterized for both tPLH (rising edge) and tPHL (falling edge) delays, with matching accuracy of ±5% or ±2 ns. The datasheet confirms leading and trailing edge precision is maintained across all taps, making the DS1010S-200 suitable for applications requiring pulse-width integrity-such as clock/data deskew or logic hazard elimination.

Can the DS1010S-200 drive modern CMOS loads, or is it limited to 74LS?

The DS1010S-200 is rated to drive up to ten 74LS loads, which corresponds to ~400 µA per output. While it can interface with modern CMOS inputs (high impedance, low current), its output stage is optimized for legacy TTL fanout. For high-speed or low-voltage CMOS (e.g., 3.3 V), verify VIH/VIL compatibility and consider buffering if loading exceeds datasheet limits. The DS1010S-200 remains electrically compatible but may require design review for non-74LS use cases.

What is the maximum operating temperature range for the DS1010S-200?

The DS1010S-200 is specified for operation from 0°C to 70°C, consistent with commercial-grade logic devices. At temperature extremes, delay shift adds ±2 ns or ±3% (whichever greater) relative to 25°C performance. This behavior is monotonic across all taps, meaning relative tap spacing remains preserved. The DS1010S-200 is not qualified for extended or industrial temperature ranges.

Is the DS1010S-200 RoHS compliant and lead-free?

The DS1010S-200 was originally released prior to RoHS enforcement and is available in both legacy SnPb and RoHS-compliant versions. Current production lots from Maxim Integrated (post-acquisition) meet RoHS Directive 2011/65/EU and JEDEC J-STD-609 moisture sensitivity level 3. Confirm RoHS status using the specific date code and packaging markings on the DS1010S-200 reel or tube label.
