| TS393 Micropower dual CMOS voltage comparators Features Extremely low supply current: typically 9 A per comparator Wide single supply range 2.7 V to 16 V or dual supplies (1.35 V to 8 V) Extremely low input bias current: 1 pA typical Extremely low input offset current: 1 pA typical Input common-mode voltage range includes ground High input impedance: 1012 typ Fast response time: 2.5 s typ. for 5 mV overdrive Pin-to-pin and functionally compatible with dual bipolar LM393 N DIP8 (Plastic package) D SO-8 (Plastic micropackage) Description The TS393 is a micropower CMOS dual voltage comparator with extremely low consumption of 9 A typically per comparator (20 times less than the dual bipolar LM393). Similar performance is offered by the dual micropower comparator TS3702 with a push-pull CMOS output. Thus response times remain similar to the LM393.

All voltage values, except differential voltage, are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. Excursions of input voltages may exceed the power supply level. As long as the common mode voltage [Vicm=(Vin+ + Vin-)/2] remains within the specified range, the comparator will provide a stable output state. However, the maximum current through the ESD diodes (IF) of the input stage must strictly be observed. 4. Guaranteed by design. 5. Short-circuits can cause excessive heating and destructive dissipation. Values are typical. 6. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 7. Machine model: A 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 ). This is done for all couples of connected pin combinations while the other pins are floating. 8. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. 2/12 TS393 Table 2.
