TI TLC3704CD

The TLC3704 consists of four independent micropower voltage comparators designed for single-supply operation, compatible with modern HCMOS logic systems. They are functionally similar to the LM339 but consume only one-twentieth the power at comparable response times. The push-pull CMOS output stage can directly drive capacitive loads and achieves specified response times without power-consuming pull-up resistors. Eliminating pull-up resistors not only reduces power consumption but also saves board space and component costs. The output stage is also fully TTL-compatible. The LinCMOS process provides superior analog performance compared to standard CMOS processes. In addition to the inherent advantages of standard CMOS — low power without sacrificing speed, high input impedance, and low bias current — the LinCMOS process delivers extremely stable input offset voltage under large differential input voltages, a characteristic that makes it possible to produce reliable CMOS comparators. The TLC3704C is rated for commercial temperature range operation from 0°C to 70°C; the TLC3704I is rated for extended industrial temperature range operation from -40°C to 85°C.
