description
The TLC3702 consists of two independentmicropower voltage comparators designed tooperate from a single supply and be compatiblewith modern HCMOS logic systems. They arefunctionally similar to the LM339 but use one-twentieth of the power for similar response times.The push-pull CMOS output stage drivescapacitive loads directly without a power-consuming pullup resistor to achieve the statedresponse time. Eliminating the pullup resistor notonly reduces power dissipation, but also savesboard space and component cost. The outputstage is also fully compatible with TTLrequirements.
Texas Instruments LinCMOS process offerssuperior analog performance to standard CMOSprocesses. Along with the standard CMOSadvantages of low power without sacrificingspeed, high input impedance, and low biascurrents, the LinCMOS process offersextremely stable input offset voltages with largedifferential input voltages. This characteristicmakes it possible to build reliable CMOScomparators.
The TLC3702C is characterized for operation over the commercial temperature range of 0C to 70C. TheTLC3702I is characterized for operation over the extended industrial temperature range of 40C to 85C. TheTLC3702M is characterized for operation over the full military temperature range of 55C to 125C.
