TS393 Micropower dual CMOS voltage comparators Datasheet production data Features Extremely low supply current: typically 9 A per comparator Wide single supply range 2.7 V to 16 V or dual N supplies (1.35 V to 8 V) DIP8 Extremely low input bias current: 1 pA typical (plastic package) Extremely low input offset current: 1 pA typical Input common-mode voltage range includes ground 12 High input impedance: 10 typ. D SO-8 Fast response time: 2.5 s typ. for 5 mV (plastic micropackage) overdrive Pin-to-pin and functionally compatible with dual bipolar LM393 Description P TSSOP8 The TS393 device is a micropower CMOS dual (thin shrink small outline package) voltage comparator with extremely low consumption of 9 A typically per comparator Pin connections (20 times less than the dual bipolar LM393 (top view) device). Similar performance is offered by the dual micropower comparator TS3702 with a push- pull CMOS output. + Output 1 V CC Thus response times remain similar to the LM393 Inverting input 1 Output 2 - device. + Non-inverting input 1 - Inverting input 2 - V + Non-inverting input 2 CC November 2012 Doc ID 4070 Rev 4 1/12 This is information on a product in full production. www.st.com 12Absolute maximum ratings TS393 1 Absolute maximum ratings Table 1.

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 + - V = (V + V )/2 remains within the specified range, the comparator will provide a stable output state. icm in in 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 ground through only one pin. This is done for all pins. 2/12 Doc ID 4070 Rev 4
