Overview
The TLC3704CDR, produced by Texas Instruments, is a quad micropower LinCMOS voltage comparator. This device is designed to operate from a single supply and is compatible with modern HCMOS logic systems. It is functionally similar to the LM339 but consumes significantly less power, using only 1/20th the power for similar response times. The TLC3704CDR is ideal for applications requiring low power consumption and fast response times.
