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
■ High input impedance: 10
■ Fast response time: 2.5 µs typ. for 5 mV
overdrive
■ Pin-to-pin and functionally compatible with dual
bipolar LM393
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.

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
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 200pF 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.
