LM393PS-P

Overview

The LM393PS-P is a commercial-grade dual differential comparator manufactured by Texas Instruments. It features two independent voltage comparators designed for single or dual power supply operation within a 2V to 36V range. The device utilizes an open-collector output structure compatible with TTL, MOS, and CMOS logic levels. Key electrical parameters include a typical response time of 1.3µs, a typical input offset voltage of 1mV, and a typical input bias current of 25nA. It operates within a temperature range of 0°C to +70°C and is housed in an 8-pin SOIC surface-mount package.

Feature Summary

• Dual independent voltage comparators optimized for wide-range single or dual supply operation
• Open-collector outputs enabling wired-AND logic combinations
• Low quiescent current consumption independent of supply voltage
• Input common-mode voltage range includes ground potential

Applications

• Server power supply monitoring
• Motor drive control circuits
• Industrial automation systems
• Home appliance control logic
• Wireless infrastructure equipment

Procurement Notes

Verify the specific suffix 'P' against official documentation to confirm the package type and material specifications. Ensure the component matches the required commercial temperature grade (0°C to +70°C) for your application environment. Confirm RoHS compliance status and lead-free characteristics through the manufacturer's latest datasheet before procurement.

Selection Notes

Select this component when a low-cost, general-purpose dual comparator is required for single-supply applications. It is suitable for designs needing open-collector outputs for interfacing with various logic families. Consider the 1.3µs propagation delay and 1mV offset voltage specifications to ensure they meet the precision and speed requirements of the target circuit design.

Part Context

The LM393 series represents a standard family of dual differential comparators widely used in analog signal processing. The LM393PS-P variant specifically denotes the commercial temperature grade version packaged in an 8-pin small-outline integrated circuit format. This part belongs to the broader LM293/LM393 family, sharing core functional architecture while differing in temperature ratings and package options.

Replacement Considerations

LM393DR: Pin-compatible SOIC-8 alternative from Texas Instruments. LM393N: PDIP-8 through-hole equivalent offering identical electrical performance. LM2903: Industrial temperature grade variant (-40°C to +85°C) with comparable specifications.
