NLV14490DWG

Specialty Logic Overview

The NLV14490DWG is a hex contact bounce eliminator constructed with complementary MOS enhancement mode devices. It eliminates extraneous level changes from mechanical contacts, generating a clean digital signal four clock periods after stabilization. The device features six independent debouncers per package, internal pullups on all data inputs, and diode protection on all inputs. It supports an internal R-C oscillator or external clock source, operates within a supply voltage range of 3.0 V to 18 V, and includes a Schmitt trigger on the clock input. The component is AEC-Q100 qualified and PPAP capable.

Specialty Logic Feature Summary

• Eliminates contact bounce on both make and break events using a single line input without requiring form C signals
• Integrates an internal R-C oscillator adjustable via a single external capacitor or accepts an external clock source
• Features TTL compatible data inputs and outputs with internal pullups and diode protection on all pins
• Cascadable architecture allows for longer time delays and system synchronization applications

Specialty Logic Applications

• Digital integrator and system synchronizer circuits
• Delay line generation for timing operations
• Mechanical switch and relay contact debouncing
• Asymmetrical timing circuits such as fast attack/slow release timers

Specialty Logic Procurement Notes

Verify the specific ordering suffix and package type against current onsemi documentation. Confirm that the NLV prefix meets automotive site and control change requirements if applicable. Check for discontinuation status in the latest datasheet revision history before finalizing procurement plans.

Specialty Logic Selection Notes

Select this component when multiple independent contact debouncers are required in a single package. Ensure the application voltage falls within the 3.0 V to 18 V range. Consider the internal pullup configuration for switched ground inputs and verify clock frequency requirements against the internal oscillator capabilities or external clock availability.

Specialty Logic Part Context

This part belongs to the MC14490 logic series manufactured by onsemi. It is designed for interfacing with mechanical contacts to provide stable digital signals. The device utilizes a 4-1/2-bit shift register structure for each of its six channels to process input signals relative to a clock cycle.

Specialty Logic Replacement Considerations

MC14490DWG serves as a direct functional equivalent. Verify pinout compatibility and electrical characteristics match the design requirements before substitution.
