Description
The TS3021 and TS3022 single and dual
comparators feature high-speed response time
with rail-to-rail inputs. Specified from 2V to 5V
supply voltage, these comparators can operate
over a wide temperature range: -40°C to +125°C.
The TS3021 and TS3022 comparators offer
micropower consumption as low as a few tens of
microamperes thus providing an excellent ratio of
power consumption current versus response time.
The TS3021 and TS3022 include push-pull
outputs and are available in small packages
(SMD).

Latch-up immunity
1. All voltage values, except differential voltage, are referenced to V
DD
.
2. The magnitude of input and output voltages must never exceed the supply rail ±0.3V.
3. Short-circuits can cause excessive heating. These values are typical.
4. P
D
is calculated with T
amb
=+25°C, T
j
=+150°C and corresponding R

.
5. 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.
6. 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.
