DS1100U-175+

Delay Lines IC Overview

The DS1100U-175+ is a five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced timing taps with a nominal total delay of 175ns, resulting in individual tap delays of 35ns, 70ns, 105ns, 140ns, and 175ns. The device operates on a single +5V supply within a voltage range of 4.75V to 5.25V. It utilizes an 8-pin µMAX surface-mount package and supports operation across the industrial temperature range of -40°C to +85°C. The circuit features low-power CMOS technology and is compatible with TTL/CMOS logic levels.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays

Delay Lines IC Procurement Notes

Verify the specific ordering suffix against official documentation to confirm lead-free status and packaging format. Confirm that the selected component meets the required RoHS compliance standards for your manufacturing process. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the silicon delay line.

Delay Lines IC Selection Notes

Select this part when a fixed 175ns total delay with five intermediate taps is required. Verify that the system power supply remains strictly between 4.75V and 5.25V to maintain specified timing tolerances. Ensure the operating environment falls within the -40°C to +85°C range. Consider the µMAX package dimensions during PCB layout planning.

Delay Lines IC Part Context

This component belongs to the DS1100 series of economy timing elements. The series offers various delay values ranging from 4ns to 500ns, indicated by the numeric suffix. The 'U' designation specifically identifies the 8-pin µMAX surface-mount package variant, distinguishing it from the SO package version.

Delay Lines IC Replacement Considerations

The datasheet explicitly lists the DS1100 as an improved replacement for the DS1000 series. Designers upgrading from older technologies should verify pin compatibility and ensure that the new all-silicon performance characteristics meet the original application requirements.
