TS393 Micropower dual CMOS voltage comparators Features ■ Extremely low supply current: typically 9 µA 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 N DIP8 (Plastic package) D SO-8 (Plastic micropackage) 1012 Ω typ ■ High input impedance: ■ Fast response time: 2.5 µs typ. for 5 mV overdrive ■ Pin-to-pin and functionally compatible with dual bipolar LM393 P TSSOP8 (Thin shrink small outline package) Description The TS393 is a micropower CMOS dual voltage comparator with extremely low consumption of 9 µA 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. Pin connections (top view) 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 kΩ 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 Ω). 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 Absolute maximum ratings Table 2.
