Overview
The LM393APWR is a dual analog comparator manufactured by Texas Instruments, housed in an 8-TSSOP surface-mount package. It features open-collector outputs compatible with CMOS and TTL logic families. The device operates on a single supply voltage ranging from 2 V to 36 V or dual supplies of ±1 V to ±18 V. Key electrical characteristics include a maximum input offset voltage of 5 mV at 30 V, a typical quiescent current of 2.5 mA, and a propagation delay of 700 ns. It supports a maximum output sink current of 16 mA and functions within a commercial temperature range of 0°C to +70°C.
Feature Summary
- Dual differential comparison capability within a compact surface-mount footprint
- Open-collector output structure enabling flexible interfacing with various digital logic standards
- Wide single-supply operating voltage range supporting diverse power environments
Applications
- General-purpose voltage monitoring circuits
- Threshold detection systems
- Simple time-delay generation
Procurement Notes
Verify the specific suffix 'A' indicates tighter offset voltage specifications compared to standard variants. Confirm the 'PWR' suffix corresponds to the TSSOP-8 package type and tape-and-reel packaging format. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a low-power, dual-channel comparator is required for general-purpose applications. It is suitable for designs needing wide supply voltage flexibility and open-collector outputs. Consider the 5 mV offset voltage specification if higher precision is needed compared to standard versions. Evaluate the 700 ns response time against system speed requirements to ensure adequate performance margins.
Part Context
This part belongs to the LM393 family of low-power, low-offset voltage comparators. It shares functional similarities with the LM193 and LM2903 series but offers specific package and performance variations. The LM393APWR represents a specific variant optimized for surface-mount assembly with defined electrical tolerances.
Replacement Considerations
LM393DR: Same family, SOIC-8 package. LM393N: PDIP-8 through-hole package. LM393PW: TSSOP-8 package, potentially different offset specs.
