Overview
The LM393LVPWR, produced by Texas Instruments, is a dual low-voltage comparator with a range of features that make it suitable for various applications. This device is part of the LM393LV family, which includes several package options. The LM393LVPWR is specifically packaged in a TSSOP (Thin Shrink Small Outline Package) with 8 pins, making it compact and efficient for use in space-constrained designs.
The LM393LV series is designed to operate over a wide supply voltage range of 1.65 V to 5.5 V, making it versatile for different power supply conditions. It also features rail-to-rail inputs with failsafe, ensuring that the inputs can operate up to 6 V without damage or phase inversion. Additionally, the device includes a Power-On-Reset (POR) feature that keeps the output in a High-Z state until the minimum supply voltage is reached, preventing output transients during power-up and power-down.
