DS1007S-7

Overview

The DS1007S-7 is a silicon delay line integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features seven independent buffered delays housed in a 16-SOIC package. The device operates on a single 5V supply with a voltage range of 4.75V to 5.25V and supports an input frequency up to 37.037 MHz. Four delays are fixed at 7 ns, while three delays are fixed at 25 ns. The component functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Provides seven independent buffered time delays for signal timing applications
• Features all-silicon construction with high delay tolerance accuracy
• Supports standard CMOS/TTL logic levels for broad compatibility

Applications

• Digital signal processing timing alignment
• Pulse width modulation generation
• Clock distribution network skew compensation

Procurement Notes

Verify the specific suffix 'S-7' against official datasheets to confirm the exact delay configuration of four 7ns and three 25ns taps. Confirm RoHS compliance status as older Maxim versions may not meet current environmental standards. Check for obsolescence notices from Analog Devices prior to finalizing procurement plans.

Selection Notes

Select this component when precise, fixed silicon-based delays are required without external components. Ensure the 16-SOIC package fits the PCB layout constraints. Verify that the 37.037 MHz maximum input frequency meets the system clock requirements. Consider thermal dissipation capabilities within the specified 0°C to 70°C operating range.

Part Context

The DS1007 series represents a family of programmable and fixed-delay lines designed for digital timing applications. The DS1007S-7 specifically offers a mix of short and long fixed delays, distinguishing it from fully programmable variants like the DS1007S-1. This part belongs to the legacy Maxim Integrated portfolio now managed by Analog Devices.

Replacement Considerations

Publicly confirmed substitute part numbers for the DS1007S-7 are not available in the provided documentation. Users should consult Analog Devices technical support for direct replacements or evaluate generic silicon delay lines with matching pinouts and delay values.
