description

The TLC193 and TLC393 consist of dual independent micropower voltage comparators designed to operate from a single supply. They are functionally similar to the LM393 but uses one-twentieth the power for similar response times. The open-drain MOS output stage interfaces to a variety of loads and supplies. For a similar device with a push-pull output configuration (see the TLC3702 data sheet).

Texas Instruments LinCMOS^TM process offers superior analog performance to standard CMOS processes. Along with the standard CMOS advantages of low power without sacrificing speed, high input impedance, and low bias currents, the LinCMOS^TM process offers extremely stable input offset voltages, even with differential input stresses of several volts. This characteristic makes it possible to build reliable CMOS comparators.

The TLC393C is characterized for operation over the commercial temperature range of T_A = 0°C to 70°C. The TLC393I is characterized for operation over the extended industrial temperature range of T_A = −40°C to 85°C. The TLC393Q is characterized for operation over the full automotive temperature range of T_A = −40°C to 125°C. The TLC193M and TLC393M are characterized for operation over the full military temperature range of T_A = −55°C to 125°C.
