Overview
The TLC393ID, produced by Texas Instruments, is a dual independent micropower voltage comparator designed to operate from a single supply. It is functionally similar to the LM393 but consumes one-twentieth the power for similar response times. The TLC393 series utilizes Texas Instruments' LinCMOS™ process, which offers superior analog performance compared to standard CMOS processes, including low power consumption without sacrificing speed, high input impedance, and low bias currents. The open-drain MOS output stage allows for interfacing with a variety of loads and supplies.
