LM26CIM5-YPE Simplified Block Diagram and Connection Diagram

The LM26CIM5-YPE has a fixed trip point of 115°C. For other trip point and output function availability, please see

ordering information or contact Texas Instruments.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
