Overview
The DS1135LU-15+ is a low-power, 3V high-speed silicon delay line featuring three independent buffered delays in an 8-pin uSOP 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 the commercial range (0°C to +70°C) and ±4.0ns for the industrial range (-40°C to +85°C). Active current is typically 10mA at VCC = 3.6V.
Feature Summary
- All-silicon timing circuit providing stable and precise delays over temperature and voltage variations
- Three independent logic buffered delays integrated into a single compact package
- Leading and trailing edge precision preserves input signal symmetry
Applications
- Timing circuits requiring precise pulse delay generation
- Replacement for legacy DS1033 devices
- High-speed digital signal processing synchronization
Procurement Notes
Verify RoHS compliance status by checking the specific ordering suffix against manufacturer documentation. Confirm package type availability as datasheet revisions may impact standard offerings. Ensure sourcing channels provide valid traceability for lead-free components.
Selection Notes
Select this component when a 3V operation is required alongside precise multi-channel delay capabilities. Compare delay tolerances against system requirements across the intended operating temperature range. Verify that the 8-pin uSOP footprint aligns with existing PCB layout constraints.
Part Context
This device belongs to the DS1135L series, representing a low-power, 3V evolution of earlier DS1013, DS1033, and DS1035 families. It serves as a direct replacement for the DS1033 while offering improved power efficiency and speed characteristics suitable for modern portable electronics.
