LM393PSRG4

Overview

The LM393PSRG4 is a dual differential analog comparator manufactured by Texas Instruments, designed for surface-mount applications in SOIC-8 packages. It operates within a supply voltage range of 2 V to 30 V and draws a typical operating current of 2.5 mA. The device features a response time of 1.3 µs, an input offset voltage of 5 mV, and an input bias current of 50 nA. It supports CMOS and TTL output types without a shutdown function and functions reliably across temperatures from 0°C to +70°C.

Feature Summary

• Dual differential comparison architecture
• CMOS and TTL compatible open-collector outputs
• Wide single-supply voltage operation

Applications

• Over-voltage detection circuits
• Window comparator designs
• Temperature sensing interfaces

Procurement Notes

Verify the specific suffix 'SRG4' against the manufacturer's official datasheet to confirm package type and RoHS compliance status. Confirm that the component is not subject to end-of-life restrictions or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel comparator with wide supply voltage tolerance is required. Ensure the application does not demand rail-to-rail output swing, as the device utilizes open-collector outputs requiring external pull-up resistors.

Part Context

This part belongs to the LM393 series of dual differential comparators produced by Texas Instruments. It shares functional similarities with other variants in the family but is distinguished by its specific SOIC-8 packaging and standard commercial temperature rating specifications.

Replacement Considerations

LM393DRG4 and LM393P are documented equivalents within the same product family.
