Overview
The LM306DRE4 is a high-speed voltage comparator produced by Texas Instruments. It features differential inputs, a low-impedance high-sink-current (100 mA) output, and two strobe inputs. This device is designed to detect low-level analog or digital signals and can drive digital logic, lamps, or relays directly. The LM306DRE4 offers short-circuit protection and surge-current limiting, ensuring robust operation in various environments.
The device is characterized for operation from 0°C to 70°C and can function with any negative supply voltage between −3 V and −12 V. It is available in both SOIC (Small Outline Integrated Circuit) and PDIP (Plastic Dual In-Line Package) packages, making it versatile for different design needs.
