Description
The TS3021, TS3021A 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, TS3021A 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, TS3021A includes push-pull outputs and is available in small packages (SOT23-5 and SC70-5). SC70-5 SOT23-5 Maturity status link TS3021, TS3021A

2 Absolute maximum ratings and operating conditions
Table 2. Absolute maximum ratings (AMR)
- All voltage values, except the differential voltage are referenced to (VCC-)
- The magnitude of the input and output voltages must never exceed the supply rail ±0.3 V
- Short circuits can cause excessive heating. These values are typical
- 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.
- Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the
while the other pins are floating.
- 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. Table 3. Operating conditions
