description

This device is fabricated using LinCMOSE 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 W), 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.

The TLC354 has internal electrostatic discharge (ESD) protection circuits and has been classified with a 2000-V

ESD rating tested under MIL-STD-833C, Method 3015. However, care should be exercised in handling this

device as exposure to ESD may result in degradation of the device parametric performance.

The TLC354C is characterized for operation from 0°C to 70°C. The TLC354I is characterized for operation over

the industrial temperature range of –40° to 85°C. The TLC354M is characterized for operation over the full

military temperature range –55°C to 125°C.
