Overview
The LM306D, produced by Texas Instruments, is a high-speed voltage comparator with differential inputs and a low-impedance, high-sink-current output. This device is designed to detect low-level analog or digital signals and can drive digital logic, lamps, and relays directly. It features two strobe inputs, short-circuit protection, and surge-current limiting, making it versatile for various applications. The LM306D is characterized for operation from 0°C to 70°C and is available in both SOIC (Small Outline Integrated Circuit) and PDIP (Plastic Dual In-Line Package) packages.
