This device is fabricated using LinCMOS technology and consists of two independent voltage comparators, each designed to operate from a single power supply. Operation from dual supplies is also possible if the difference between the two supplies is 2 V to 18 V. Each device features extremely high input impedance (typically greater than 1012Ω), allowing direct interfacing with high-impedance sources. The outputs are n-channel open-drain configurations and can be connected to achieve positive-logic wired-AND relationships.
The TLC372 has internal electrostatic discharge (ESD) protection circuits and has been classified with a 1000-V ESD rating using human body model testing. However, care should be exercised in handling this device as exposure to ESD may result in a degradation of the device parametric performance.
The TLC372C is characterized for operation from 0°C to 70°C. The TLC372I is characterized for operation from 40°C to 85°C. The TLC372M is characterized for operation over the full military temperature range of 55°C to 125°C. The TLC372Q is characterized for operation from 40°C to 125°C.
