LM361N

Overview

The LM361N is a high-speed differential comparator manufactured by Texas Instruments, housed in a 14-pin PDIP package. It operates within a supply voltage range of 11 V to 32 V and draws 20 mA of operating current. The device features a response time of 140 ns, an input offset voltage of 1 mV, and an input bias current of 30 uA. Designed for through-hole mounting, it supports a common-mode voltage of 9 V and functions reliably across temperatures from 0°C to +70°C.

Feature Summary

• High-speed differential comparison with strobe functionality
• Through-hole PDIP-14 packaging for standard board integration
• Operates on single or split power supplies within specified voltage limits

Applications

• High-speed signal processing circuits
• Precision timing applications requiring fast response
• Industrial control systems utilizing differential inputs

Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-14 package variant when ordering. Confirm RoHS compliance status as indicated by the NOPB designation if applicable to your procurement requirements. Ensure the supplier provides official datasheets matching the LM361N part number to validate electrical parameters against design specifications before finalizing purchase orders.

Selection Notes

Select this component when a differential output configuration is required alongside high-speed performance. The 140 ns response time suits applications demanding rapid signal transitions. Consider the 11 V minimum supply requirement during power budgeting. The through-hole format is suitable for prototyping or environments where mechanical robustness is prioritized over surface-mount density.

Part Context

The LM361 belongs to a family of analog comparators designed for precision and speed. The LM361N specifically denotes the plastic dual-in-line package version. This series is engineered for applications requiring accurate voltage comparison with minimal delay, distinguishing it from general-purpose comparators that may offer slower speeds but lower power consumption.

Replacement Considerations

Cross-reference with LM361H/NOPB for TO-100-10 package compatibility or LM361M/NOPB for SOIC surface-mount alternatives. Verify pinout consistency and thermal characteristics when substituting packages to ensure circuit board layout compatibility without redesign.
