Overview
The LM3302N/NOPB is a quad differential voltage comparator manufactured by Texas Instruments. It features four independent comparators housed in a 14-pin DIP package. The device operates within a power supply voltage range of 2V to 28V and supports output types including CMOS, MOS, Open Collector/Drain, and TTL. It has a typical response time of 300ns and functions across an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates four independent differential comparators for multi-channel signal processing
- Supports multiple logic output interfaces including CMOS, TTL, and open collector configurations
- Operates on a single wide-range power supply without requiring dual rails
Applications
- General purpose analog signal comparison circuits
- Interface between analog sensors and digital logic systems
- Voltage monitoring and threshold detection applications
Procurement Notes
Verify the specific suffix 'NOPB' indicates lead-free compliance when ordering. Confirm the 'N' designation corresponds to the standard 14-pin DIP package variant. Ensure the component meets RoHS requirements for your assembly process. Cross-reference the manufacturer part number with official datasheets to confirm pinout compatibility before integration into existing designs.
Selection Notes
Select this component when a quad comparator configuration is required in a through-hole package. It is suitable for designs needing flexible output logic levels such as TTL or CMOS compatibility. Consider the 300ns response time for speed requirements. Verify that the 2V to 28V supply range aligns with the system power architecture.
Part Context
This part belongs to the LM3302 series of analog comparators from Texas Instruments. The series provides high-gain differential amplification optimized for voltage comparison tasks. The NOPB suffix typically denotes environmental compliance, while the N suffix specifies the plastic dual in-line package format used for prototyping and through-hole manufacturing.
Replacement Considerations
The LM3302DR is a surface-mount alternative offering identical electrical specifications in an SOIC-14 package. Designers requiring a different package style should verify pinout compatibility and thermal characteristics before substitution.
