DS1000C-703/T&R

Overview

The DS1000C-703/T&R is a five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced time delays with a nominal value of 3 ns per tap, resulting in tap outputs at 3 ns, 6 ns, 9 ns, 12 ns, and 15 ns relative to the input signal. The device features a delay tolerance of ±5% or ±2 ns, whichever is greater. It operates on a single +5V supply (4.75V to 5.25V) and draws a typical active current of 35 mA. The component supports TTL/CMOS-compatible logic levels and includes five independent output taps capable of driving up to ten 74LS loads.

Feature Summary

• Provides five equally spaced output taps for precise timing control
• Reproduces both leading and trailing edges with equal precision
• Low-power CMOS construction compatible with standard TTL and CMOS logic families

Applications

• Timing circuit generation requiring multiple synchronized delayed signals
• Pulse width modulation and shaping applications
• Digital logic synchronization and clock distribution networks

Procurement Notes

Verify the specific suffix 'T&R' indicates tape and reel packaging when sourcing this component. Confirm that the manufacturer designation matches Analog Devices Inc. or Maxim Integrated, as these entities have undergone corporate transitions. Ensure the part number corresponds exactly to the 3 ns delay variant before procurement.

Selection Notes

Select this component when fixed, equally spaced delay intervals are required without programmable adjustment. Verify that the 3 ns nominal delay meets the system timing requirements. Consider the package availability, as surface mount options exist alongside traditional DIP formats. Evaluate the power consumption against available supply rails, noting the 5V requirement.

Part Context

This component belongs to the DS1000 series of all-silicon delay lines, which serve as solid-state replacements for hybrid delay line technologies. The series offers superior reliability and lower cost compared to older hybrid implementations while maintaining pin compatibility with industry-standard packages. The DS1000 series allows for customization of delay values and packaging configurations upon request.

Replacement Considerations

Direct replacement requires verifying pinout compatibility with existing hybrid delay lines. Alternative silicon delay lines from other manufacturers may require schematic modifications due to differing pin assignments or electrical characteristics.
