6.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)| MIN | MAX | UNIT | |||
|---|---|---|---|---|---|

(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 voltages are with respect to ground, unless otherwise specified.
(3) The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
(4) VI and VO are used to denote specific conditions for VI/O.
(5) II and IO are used to denote specific conditions for II/O.
6.2 ESD Ratings

|---|---|---|---|---|
| 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.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

(1) VIN and IIN refer to control inputs. VI, VO, II, and IO refer to data pins.
(2) All typical values are at VCC = 3.3 V (unless otherwise noted), TA = 25°C.
(3) For I/O ports, the parameter IOZ includes the input leakage current.
(4) This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VCC or GND.
(5) Measured by the voltage drop between A and B terminals at the indicated current through the switch. ON-state resistance is determined by the lower of the voltages of the two (A or B) terminals.
