LM361M

Overview

The LM361M is a high-speed differential comparator manufactured by Texas Instruments, housed in a 14-SOIC package. It operates within a supply voltage range of 11 V to 32 V and draws 20 mA of operating supply current. The device features a response time of 140 ns, an input offset voltage of 1 mV, and an input bias current of 30 µA. It supports a common-mode voltage of 9 V and functions reliably across a temperature range of 0°C to +70°C.

Feature Summary

• High-speed differential comparison capability with strobe functionality
• Single-channel analog comparator design for signal processing
• Through-hole compatible SOIC packaging for circuit integration

Applications

• High-speed data acquisition systems
• Voltage monitoring circuits
• Pulse generation applications

Procurement Notes

Verify the specific suffix (e.g., NOPB) against official datasheets to confirm lead-free compliance and exact package variant. Confirm the manufacturer source directly from Texas Instruments documentation rather than distributor listings. Ensure the part number matches the required 14-SOIC form factor and operational temperature range for your specific design constraints before ordering.

Selection Notes

Select this component when a single differential comparator with high speed is required. The 14-pin SOIC package suits surface-mount designs needing robust isolation. Verify that the 11 V minimum supply voltage aligns with system power rails. Consider the 140 ns response time for timing-critical applications requiring fast signal discrimination.

Part Context

The LM361M belongs to the LM361 family of high-speed differential comparators from Texas Instruments. This series is designed for applications demanding rapid signal switching and precise voltage threshold detection. The M suffix typically denotes the SOIC package variant within the broader LM361 product line.

Replacement Considerations

LM361MX/NOPB: Same functional specifications with reel packaging instead of tube.
