7.1 Absolute Maximum Ratings
over operating junction temperature range (unless otherwise noted)(1)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| Supply voltage(2) | VDD | –0.3 | 4 | V |
| MR Pin, RESET (push-pull) | VMR, VRESET (push-pull) | –0.3 | VDD + 0.3 | V |
| All other pins(2) | –0.3 | 4 | V | |
| Maximum low output current | IOL | –5 | 5 | mA |
| Maximum high output current | IOH | –5 | 5 | mA |
| Input current | IIK (VSENSE < 0 V or VSENSE > VDD) | –10 | 10 | mA |

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to GND. For reliable operation, the device must not be operated at 3.6 V for more than t = 1000h continuously.
(3) Output is clamped for push-pull outputs by the back gate diodes internal to the IC. No clamp exists for the open-drain outputs.
7.2 ESD Ratings
| VALUE | UNIT | |||
|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) | ±2000 | V |
| Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) | ±500 | |||
(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.
