DS1100U-20+

Delay Lines IC Overview

The DS1100U-20+ is a five-tap silicon delay line from the DS1100 series, manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced timing taps with a total nominal delay of 20ns, where individual tap delays range from 4ns to 20ns. The device operates on a single 5V supply within a voltage range of 4.75V to 5.25V and functions across an industrial temperature range of -40°C to +85°C. Packaged in an 8-pin µMAX surface-mount format, it features TTL/CMOS-compatible logic levels and can drive up to ten 74LS loads per tap.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing stable and precise delays for both leading and trailing edges
• Five equally spaced taps allowing flexible timing configuration without programming
• Low-power CMOS technology compatible with standard TTL and CMOS logic families

Delay Lines IC Applications

• Timing element replacement for legacy hybrid delay lines
• Pulse width extension or compression circuits
• Clock skew adjustment in digital systems

Delay Lines IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status indicated by the '+' suffix. Ensure storage conditions remain within specified limits to maintain reliability. Check for lead-free soldering compatibility if required by assembly processes.

Delay Lines IC Selection Notes

Select this model when a fixed 20ns total delay with five intermediate steps is required. Consider the µMAX package for space-constrained surface-mount designs. Verify that the 5V operating voltage aligns with system power rails. Evaluate thermal requirements against the -40°C to +85°C industrial range.

Delay Lines IC Part Context

Part of the DS1100 family of economy timing elements designed to replace older hybrid technologies. The 'U' designation indicates the µMAX surface-mount package variant. The '-20' suffix specifies the 20ns total delay characteristic. This series offers improved reliability over previous generations like the DS1000.

Delay Lines IC Replacement Considerations

DS1000 series devices serve as predecessors. Verify pinout compatibility during transition. No direct equivalent part numbers are listed in official documentation for immediate drop-in substitution beyond the DS1000 lineage.
