8.1 Absolute Maximum Ratings
| MIN | MAX | UNIT | |||
|---|---|---|---|---|---|
| VIN | Input voltage range | –0.3 | 6 | V | |
| VOUT | Output voltage range | –0.3 | 6 | V | |
| VON | Input voltage range | –0.3 | 6 | V | |
| IMAX | Maximum continuous switch current | 2 | A | ||
| IPLS | Maximum pulsed switch current, pulse < 300 µs, 2% duty cycle | 2.5 | A | ||
| TA | Operating free-air temperature range | –40 | 85 | °C | |
| TJ | Maximum junction temperature | 125 | °C | ||
| Tstg | Storage temperature range | –65 | 150 | °C | |
8.2 ESD Ratings
| VALUE | UNIT | |||
|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) | ±2000 | V |
| Charged-device model (CDM), per JEDEC specification JESD22-C101(2) | ±1000 | |||
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions. Pins listed as ±2000 V may actually have higher performance.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions. Pins listed as ±1000 V may actually have higher performance.
8.3 Recommended Operating Conditions

|---|---|---|---|---|---|
| VIN | Input voltage range | 1.4 | 5.5 | V | |
| VON | ON voltage range | 0 | 5.5 | V | |
| VOUT | Output voltage range | VIN | |||
| VIH | High-level input voltage, ON | VIN = 1.4 V to 5.5 V | 1.1 | 5.5 | V |
| VIL | Low-level input voltage, ON | VIN = 3.61 V to 5.5 V | 0.6 | V | |
