DS1135U-25+

Overview

The DS1135U-25+ is a low-power, +5V high-speed silicon delay line featuring three independent buffered delays in a single package. It provides a nominal delay of 25ns per output with an initial tolerance of ±1.5ns at +25°C and VCC = +5.0V. The device operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range from -40°C to +85°C. It utilizes an 8-pin uSOP (uMAX) surface-mount package.

Feature Summary

• All-silicon timing circuit providing stable and precise delays over temperature and voltage variations
• Three independent buffered delay outputs capable of driving up to 10 LS loads
• Leading and trailing edge precision preserves input symmetry

Applications

• Replacement for DS1013 and DS1035 delay lines
• High-speed signal timing applications requiring precise pulse width control
• Digital logic circuits needing multiple independent delay taps

Procurement Notes

Verify the specific package suffix against current manufacturer documentation, as datasheet revisions may update available packages. Confirm RoHS compliance status via the ordering information section. Check for end-of-life notifications or discontinuance notices prior to procurement planning.

Selection Notes

Select this component when a 25ns fixed delay is required for three independent channels. Ensure the design accommodates the 8-pin uSOP footprint. Verify that the system power supply remains within the 4.75V to 5.25V range to maintain specified timing tolerances across the industrial temperature range.

Part Context

The DS1135 series represents a family of 3-in-1 high-speed silicon delay lines. This specific part is the 25ns variant within the 5V operation line, distinct from the 3V DS1135L series. It serves as a direct functional replacement for legacy discrete delay solutions or older integrated parts like the DS1013.
