DS1100M-500+

Delay Lines IC Overview

The DS1100M-500+ is a five-tap silicon delay line providing equally spaced delays from 4ns to 500ns. It operates on a single +5V supply and features low-power CMOS technology with TTL/CMOS compatibility. The device offers stable and precise timing for both leading and trailing edges, with each tap capable of driving up to ten 74LS loads. Designed for surface-mount applications, it utilizes industry-standard µMAX or SO packages to minimize PCB area while ensuring superior reliability over hybrid technologies.

Delay Lines IC Feature Summary

• All-silicon timing circuit with five equally spaced taps
• Low-power CMOS construction with TTL/CMOS-compatible logic levels
• Precise reproduction of both leading and trailing signal edges
• Stable delay performance across commercial and industrial temperature ranges

Delay Lines IC Applications

• Precision timing circuits requiring fixed signal delays
• Pulse width modulation systems
• Digital logic synchronization tasks
• Replacement for legacy DS1000 series components

Delay Lines IC Procurement Notes

Verify the specific ordering suffix to confirm package type and RoHS compliance status. The '+' suffix indicates a lead-free/RoHS-compliant package. Ensure the thermal profile matches vapor-phase, IR, or wave soldering requirements. Confirm the -500 designation corresponds to the required 500ns total delay span before procurement.

Delay Lines IC Selection Notes

Select this component when a fixed, multi-tap delay solution is required without external programming. The -500 variant provides nominal delays of 100ns, 200ns, 300ns, 400ns, and 500ns at Taps 1 through 5 respectively. Consider the operating temperature range of -40°C to +85°C for industrial environments. Verify input pulse width and period constraints against the AC electrical characteristics table.

Delay Lines IC Part Context

This device belongs to the DS1100 series of economy timing elements manufactured by Maxim Integrated (now Analog Devices). It serves as an improved replacement for the older DS1000 series, offering better reliability through all-silicon construction. The series is designed to provide cost-effective, precise delay lines in compact surface-mount packages for digital timing applications.

Delay Lines IC Replacement Considerations

The datasheet explicitly identifies the DS1100 as an improved replacement for the DS1000 series. When substituting, verify that the pinout and voltage requirements remain compatible. Note that the DS1100 uses µMAX or SO packages, whereas older variants may have used DIP packages which are no longer available.
