The TLC139/TLC339 consists of four independent differential-voltage comparators designed to operate from a single supply. It is functionally similar to the LM139/LM339 family but uses 1/20th the power for similar response times. The open-drain MOS output stage interfaces to a variety of leads and supplies, as well as wired logic functions. For a similar device with a push-pull output configuration, see the TLC3704 data sheet.
The Texas Instruments LinCMOS 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 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 TLC139M and TLC339M are characterized for operation over the full military temperature range of 55°C to 125°C. The TLC339C is characterized for operation over the commercial temperature range of 0°C to 70°C. The TLC339I is characterized for operation over the industrial temperature range of 40°C to 85°C. The TLC339Q is characterized for operation over the extended industrial temperature range of 40°C to 125°C.
