EXTREMELY LOW SUPPLY CURRENT : 9µA TYP/COMPARATOR WIDE SINGLE SUPPLY RANGE (3V to 16V) OR DUAL SUPPLIES (±1.5V to ±8V) EXTREMELY LOW INPUT BIAS CURRENT : 1pA TYP EXTREMELY LOW INPUT OFFSET CURRENT : 1pA TYP INPUT COMMON-MODE VOLTAGE RANGE INCLUDES GND HIGH INPUT IMPEDANCE 1012Ω TYP FAST RESPONSE TIME : 2.5µs TYP FOR 5mV OVERDRIVE PIN-TO-PIN AND FUNCTIONALLY COMPATIBLE WITH BIPOLAR LM393 DESCRIPTION N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) P TSSOP8 (Thin Shrink Small Outline Package) ORDER CODES The TS393 is a micropower CMOS dual voltage comparator with extremely low consumption of 9µA typ / comparator (20 times less than bipolar LM393). Similar performances are offered by the dual micropower comparator TS3702 with a pushpull 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. The output must never exceed the power supply voltage. 4. Guaranteed by design. 5. Short circuit from outputs to VCC+ can cause excessive heating and eventual destruction.
