| TS3021-TS3022 Rail-to-rail 1.8V high-speed comparator Features Propagation delay: 33ns Low current consumption: 64A Rail-to-rail inputs Push-pull outputs Supply operation from 1.8V to 5V Wide temperature range: -40C to +125C ESD tolerance: 2kV HBM / 200V MM Latch-up immunity: 200mA SMD packages TS3021 SOT23-5 / SC70-5 Pin connections (top view) OUT VccIN+ 1 2 + 3 4 IN5 Vcc+ Applications Telecom Instrumentation Signal conditioning High-speed sampling systems Portable communication systems TS3022 SO-8 / MiniSO-8 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: -40C to +125C. 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=+25C, Tj =+150C and corresponding Rthja . 5. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5k 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 < 5). This is done for all couples of connected pin combinations while the other pins are floating. 2/16 TS3021-3022 Table 2.
