LM393P-NG

Overview

The LM393P-NG is a commercial-grade dual differential voltage comparator manufactured by Texas Instruments. It features an open-collector output structure compatible with TTL, MOS, and CMOS logic levels. The device supports single-supply operation from 2V to 36V or dual supplies where the difference is between 2V and 36V. Key electrical parameters include a typical response time of 1.3µs, input offset voltage of 1mV, and static current of 200µA per comparator. It utilizes a PDIP-8 through-hole package with dimensions of 9.81mm x 6.35mm x 4.57mm and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Dual independent voltage comparators designed for wide voltage range single-supply operation
• Open-collector outputs allow wired-AND connection capabilities
• Input common-mode voltage range includes ground potential

Applications

• Server power supply monitoring
• Motor drive control circuits
• Industrial automation systems
• Home appliance control logic
• Building automation sensors

Procurement Notes

Verify that the specific suffix 'NG' corresponds to the standard PDIP-8 package configuration documented in official Texas Instruments datasheets. Confirm RoHS compliance status and lead-free material specifications directly from the manufacturer's ordering information. Ensure the component matches the commercial grade temperature rating of 0°C to +70°C required for the intended application environment.

Selection Notes

Select this component when a low-cost, general-purpose dual comparator with ground-referenced input capability is required. The open-collector output necessitates an external pull-up resistor for proper logic level generation. Consider the 1.3µs propagation delay for timing-sensitive applications and ensure the supply voltage remains within the specified 2V to 36V operational window.

Part Context

This part belongs to the LM393 family of analog comparators, widely used in general-purpose electronic designs. The PDIP-8 package variant provides through-hole mounting options suitable for prototyping and legacy board designs. It serves as a fundamental building block for signal conditioning and threshold detection tasks in consumer and industrial electronics.
