Description
The TS3022 dual comparator features a high-
speed response time with rail-to-rail inputs. With a
supply voltage specified from 2 to 5 V, this
comparator can operate over a wide temperature
range: -40° C to +125° C.
The TS3022 comparator offers micropower
consumption as low as a few tens of
microamperes thus providing an excellent ratio of
power consumption current versus response time.
The TS3022 includes push-pull outputs and is
available in small packages (SMD): SO-8 and
MiniSO-8.

Human body model (HBM)(4)
4. 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.

VMachine model (MM)(5)
5. 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.
300
Charged device model (CDM)(6)
6. 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.
