TLC354 Datasheet (Texas Instruments) - QUADRUPLE DIFFERENTIAL COMPARATORS

TLC354, QUADRUPLE DIFFERENTIAL COMPARATORS

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.

* 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 su
