Overview
The LM393PWG4 is a dual differential comparator manufactured by Texas Instruments, belonging to the LM393 series. It features two independent high-gain comparators in an 8-pin TSSOP package. The device operates with a single power supply ranging from 2 V to 30 V or dual supplies of ±1 V to ±15 V. Key electrical parameters include a typical response time of 1.3 µs, a maximum input offset voltage of 5 mV, and a quiescent current of 2.5 mA. The output stage is open-collector, compatible with CMOS and TTL logic families.
Feature Summary
- Dual differential comparison capability within a compact surface-mount package
- Open-collector output structure ensuring compatibility with various logic families
- Wide single-supply operating range supporting diverse voltage levels
Applications
- Over-voltage and under-voltage detection circuits
- Temperature sensing and control systems
- Peak voltage detection applications
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the TSSOP-8 package dimensions match the design footprint requirements. Ensure the component status is active, as some variants may be subject to obsolescence notices. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications.
Selection Notes
Select this component when dual independent comparison is required in a space-constrained design. The open-collector output necessitates external pull-up resistors for proper logic level generation. Consider the 1.3 µs propagation delay for timing-sensitive applications. Verify that the 30 V maximum supply voltage meets the system's operational limits.
Part Context
The LM393PWG4 is part of the widely used LM393 family of dual comparators. It serves as a standard solution for general-purpose analog signal conditioning and threshold detection. The 'P' designation identifies the TSSOP-8 package, while 'G4' denotes environmental compliance. This component is commonly integrated into industrial control boards and consumer electronics.
Replacement Considerations
LM393DRG4: Pin-compatible SOIC-8 alternative with identical electrical characteristics. LM393N: PDIP-8 through-hole version for prototyping or legacy board upgrades. LM2903: Automotive-grade variant with extended temperature range and enhanced reliability specifications.
