LM360MX

Overview

The LM360MX is a high-speed, low-voltage differential comparator manufactured by Texas Instruments. It features a dual open-collector output configuration housed in an 8-pin SOIC package. The device operates within a supply voltage range of ±4.5V to ±6.5V. Key electrical specifications include a maximum propagation delay of 130ns and a maximum input bias current of 20µA. The typical response time is documented at 0.08μs for related variants, with a maximum input offset voltage of 5mV.

Feature Summary

• High-speed differential comparison capability
• Low-voltage operation suitable for portable applications
• Dual open-collector outputs for flexible interfacing

Applications

• High-speed signal processing circuits
• Low-voltage monitoring systems
• Portable electronic devices requiring fast switching

Procurement Notes

Verify the specific suffix (e.g., MX vs. MX/NOPB) against the manufacturer's current datasheet to ensure compliance with RoHS directives and material composition requirements. Confirm that the SOIC-8 package dimensions match the target PCB footprint. Cross-reference the operating temperature range with the intended application environment to ensure reliability under thermal stress conditions.

Selection Notes

Select this component when a fast response time is critical within a low-voltage power budget. The differential input structure allows for precise threshold detection without common-mode interference. Ensure the load connected to the open-collector outputs can handle the required pull-up voltages. Consider the 20µA input bias current for high-impedance source applications to minimize measurement errors.

Part Context

The LM360 belongs to Texas Instruments' family of high-speed comparators designed for low-voltage environments. Unlike standard single-ended comparators, this model provides differential inputs, enhancing noise immunity in sensitive analog circuits. The SOIC-8 packaging facilitates surface-mount assembly, supporting automated manufacturing processes while maintaining a compact form factor for space-constrained designs.

Replacement Considerations

The LM360MX/NOPB is the lead-free version of the LM360MX. Verify pin compatibility if substituting with other high-speed comparators from different manufacturers. Ensure alternative parts support the same ±4.5V to ±6.5V supply range and offer comparable propagation delays.
