7.1 Absolute Maximum Ratings(1)
over operating free-air temperature range (unless otherwise noted)| MIN | MAX | UNIT | |||
|---|---|---|---|---|---|
| VCC | Supply voltage range | –0.5 | 6.5 | V | |
| VI | Input voltage range(2) | –0.5 | 6.5 | V | |
| VO | Voltage range applied to any output in the high-impedance or power-off state(2) | –0.5 | 6.5 | V | |
| VO | Voltage range applied to any output in the high or low state(2)(3) | –0.5 | VCC + 0.5 | V | |
| IIK | Input clamp current | VI < 0 | –50 | mA | |
| IOK | Output clamp current | VO < 0 | –50 | mA | |
| IO | Continuous output current | ±50 | mA | ||
| Continuous current through VCC or GND | ±100 | mA | |||
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
(3) The value of VCC is provided in the Recommended Operating Conditions table.
7.2 Handling Ratings
| MIN | MAX | UNIT | |||
|---|---|---|---|---|---|
| Tstg | Storage temperature range | –65 | 150 | °C | |
| V(ESD) | Electrostatic discharge | Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) | 0 | 2000 | V |
| Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) | 0 | 1000 | |||
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
7.3 Recommended Operating Conditions
over operating free-air temperature range (unless otherwise noted)(1)(1) All unused inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, (SCBA004).
