TLC354CPWR

模拟比较器 Quad Low Vltg LinCMOS Differential

description

This device is fabricated using LinCMOS technology and consists of four independent differential voltage comparators; each is designed to operate from a single power supply. Operation from dual supplies is also possible if the difference between the two supplies is 1.4 V to 18 V. Each device features extremely high input impedance typically greater than 1012 Ω, which allows direct interface to high-impedance sources. The outputs are n-channel open-drain configurations and can be connected to achieve positive-logic wired-AND relationships. The capability of the TLC354 to operate from a 1.4-V supply makes this device ideal for low-voltage battery applications.
