DS1135LZ-15

Delay Lines IC Overview

The DS1135LZ-15 is a low-power, 3V high-speed silicon delay line featuring three independent buffered delays in an 8-pin SOIC package. It operates within a supply voltage range of 2.7V to 3.6V and supports temperatures from -40°C to +85°C. The nominal delay per output is 15ns with an initial tolerance of ±1.0ns at +25°C. Tolerance over temperature and voltage ranges is specified as ±2.5ns for commercial (0°C to +70°C) and ±4.0ns for industrial (-40°C to +85°C) conditions. Active current is typically 10mA at VCC = 3.6V.

Delay Lines IC Feature Summary

• All-silicon timing circuit providing inherent reliability
• Three independent logic buffered delays in a single package
• Stable and precise performance over temperature and voltage variations
• Leading and trailing edge precision preserves input symmetry

Delay Lines IC Applications

• Replacement for DS1033 series components
• Precision timing applications requiring stable delays
• Systems needing multiple independent delay lines in compact packaging

Delay Lines IC Procurement Notes

Verify RoHS compliance status by checking the ordering suffix, as indicated by datasheet conventions. Confirm package type Z corresponds to the 150-mil SOIC format. Ensure supply voltage requirements align with the 2.7V to 3.6V operational range before procurement.

Delay Lines IC Selection Notes

Select this component when a 3V operation is required instead of the standard 5V DS1135 series. Verify that the 15ns delay meets system timing constraints. Consider the ±4.0ns worst-case tolerance for industrial temperature environments during design validation.

Delay Lines IC Part Context

The DS1135LZ-15 belongs to the DS1135L series, which serves as the 3V counterpart to the popular DS1013, DS1033, and DS1035 delay lines. It offers faster performance compared to these predecessors while maintaining the same functional architecture of three independent delays.
