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 an industrial temperature range from -40°C to +85°C. The nominal propagation delay for each output tap is 15ns with an initial tolerance of ±1.0ns at +25°C. Over the full operating temperature and voltage range, the delay tolerance extends to ±4.0ns. The device maintains input symmetry through precise leading and trailing edge accuracy.
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
- Preserves input symmetry via leading and trailing edge precision
Applications
- Replacement for DS1033 delay lines
- Precision timing applications requiring stable delays
- Systems needing multiple independent buffered delays
Procurement Notes
Verify RoHS compliance status by checking the ordering suffix, as indicated in the datasheet. Confirm that the specific package type matches the required footprint, noting that the Z suffix denotes the 150-mil SOIC package. Ensure the supplier provides documentation confirming the lead-free status if required by the manufacturing process.
Selection Notes
Select this component when a 3V operation is required instead of the standard 5V DS1135 series. Choose the 15ns delay variant specifically for timing requirements matching this value. Verify that the 8-pin SOIC package fits the board layout constraints. Consider the ±4.0ns worst-case tolerance over temperature when designing critical timing paths.
Part Context
The DS1135L series serves as the 3V version of the popular DS1013, DS1033, and DS1035 series. It is described as the fastest 3-in-1 delay line in its category. The Z suffix identifies the 150-mil 8-pin SOIC package option available for this family.
