Description
The TS3021 single comparator features 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 TS3021 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 TS3021 includes push-pull outputs and is
available in small packages (SOT23-5 and
SC70-5).

The magnitude of the input and output voltages must never exceed the supply rail ±0.3 V

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.
(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.
(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.

Electrical characteristics
All values over the temperature range are guaranteed through correlation and simulation. No production test is performed at the
temperature range limits
(2)
(3)
Maximum values include unavoidable inaccuracies of the industrial tests
Response time is measured 10%/90% of the final output value with the following conditions: inverting input voltage (IN-) = Vicm
and non-inverting input voltage (IN+) moving from Vicm - 100 mV to Vicm + overdrive.
