Specified from 2V to 5V supply voltage, these comparators can operate over a wide temperature range: -40°C to +125°C. Output 1 1 Inverting Input 1 2 _ Non Inverting Input 1 3 + VDD 4 8 VCC 7 Output 2 _ 6 Inverting Input 2 + 5 Non Inverting Input 2 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).

All voltage values, except differential voltage, are referenced to VDD. 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. PD is calculated with Tamb=+25°C, Tj =+150°C and corresponding Rthja . 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. 2/16 TS3021-3022 Absolute maximum ratings and operating conditions Table 2.
