TS393
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
High input impedance: 1012 Ω typ.
Fast response time: 2.5 µs typ. for 5 mV
overdrive
Pin-to-pin and functionally compatible with dual
bipolar LM393
Description
The TS393 device 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
device). Similar performance is offered by the
dual micropower comparator TS3702 with a push-
pull CMOS output.
Thus response times remain similar to the LM393
device.

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
[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 ground through only one pin. This is done for all pins.
