Description
The TS3702 is a micropower CMOS dual voltage
comparator with extremely low consumption of
9μA typ / comparator (20 times less than bipolar
LM393). The push-pull CMOS output stage allows
power and space saving by eliminating the
external pull-up resistor required by usual open-
collector output comparators.

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. The magnitude of the input and the output voltages must never exceed the magnitude of the positive and
negative supply voltages.
4. Guaranteed by design.
5. Pd is calculated with Tamb = +25°C, Tj = +150°C and
R
thja = 100°C/W for DIP8 package
Rthja = 175°C/W for SO8 package
Rthja = 200°C/W for TSSOP8 package
6. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a
1.5kΩ 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 < 5Ω). 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.
