Ω typ
Fast response time: 2μs typ for 5mV overdrive
Pin-to-pin and functionally compatible with
bipolar LM393
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.
Thus response times remain similar to the LM393.

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.
