Overview
The CD8447DR2G is a quad channel voltage comparator manufactured by onsemi. It integrates four independent high-speed comparators within a single package, designed for applications requiring multiple threshold detection functions. The device operates with a wide supply voltage range and features low input bias current. It is available in a surface-mount package suitable for automated assembly processes.
Feature Summary
- Integrates four independent high-speed comparators for multi-channel signal processing
- Designed for wide supply voltage operation to accommodate various system requirements
- Features low input bias current for accurate sensing of high-impedance sources
Applications
- Multi-channel threshold detection circuits
- Voltage monitoring systems
- Signal conditioning interfaces
Procurement Notes
Verify the exact datasheet revision and electrical specifications directly from onsemi official documentation before integration. Confirm package pinout compatibility with your PCB layout. Ensure operating conditions remain within the absolute maximum ratings specified in the manufacturer's data sheet to prevent device failure.
Selection Notes
Select this component when a design requires four separate comparator channels in a compact form factor. Consider the supply voltage range and propagation delay characteristics against your specific signal timing requirements. Evaluate thermal performance if multiple channels are operated simultaneously at high frequencies.
Part Context
This part belongs to the family of linear comparators offered by onsemi. It serves as a solution for designs needing multiple voltage comparison functions without occupying excessive board space. The quad configuration simplifies circuit architecture compared to using discrete single comparators.
Replacement Considerations
Consult onsemi official documentation for verified substitute part numbers. Do not assume functional equivalence with other quad comparators without verifying pinout and electrical parameter alignment.
