Overview
The LM393N is a low-power, low-offset voltage dual comparator from Texas Instruments. It operates on single supplies from 2.0 V to 36 V or dual supplies of ±1.0 V to ±18 V. The device features an open-collector output compatible with TTL, DTL, ECL, MOS, and CMOS logic systems. Key electrical parameters include a maximum offset voltage of 9 mV, typical supply current of 0.4 mA at 5 V, and a response time of 1.3 μs. It supports input common-mode voltages that include ground.
Feature Summary
- Low power consumption independent of supply voltage
- Input common-mode voltage range includes ground
- Open-collector outputs allow wired-OR connections
- Compatible with various logic families including TTL and CMOS
Applications
- Battery powered applications
- Industrial applications
- Limit comparators
- Simple analog to digital converters
- Pulse, squarewave and time delay generators
Procurement Notes
Verify the specific manufacturer part number against official TI documentation to ensure authenticity. Confirm package type matches requirements as the LM393 series is available in multiple formats. Check for RoHS compliance status if required by your manufacturing standards. Ensure operating conditions align with the commercial temperature range specifications provided in the datasheet.
Selection Notes
Select this component when low power drain is critical for battery-operated systems. The wide single-supply voltage range simplifies design across different voltage levels. Use when interfacing with high-impedance nodes due to low input bias current. Consider the open-collector output structure for flexible logic level translation and wired-OR configurations in complex digital circuits.
Part Context
The LM393N belongs to the LMx93-N family of precision voltage comparators designed specifically for single-supply operation. This series eliminates the need for dual supplies while maintaining high precision. The N suffix indicates a PDIP-8 through-hole package variant suitable for general-purpose circuit prototyping and industrial equipment requiring robust physical mounting.
Replacement Considerations
LM193N, LM293N, LM2903N are electrically similar variants within the same family offering comparable performance characteristics.
