These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(2) All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to ground unless
otherwise specified except V

(3) “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be ensured. They are not meant to imply
that the devices should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device
operation.
(4) All typicals are given for V

= +25°C, unless otherwise stated.
(5) ESD Rating: HBM (1.5 kΩ, 100 pF) > 4 kV EIAJ (0Ω, 200 pF) > 250.
(6) Package must be mounted to pc board in accordance with AN-1187 (SNOA401) to achieve thermals.

= <1.0 ns (0%–100%). To ensure fastest
propagation delay and minimum skew, data input edge rates should be equal to or faster than 1ns/V; control signals equal to or faster
than 3ns/V. In general, the faster the input edge rate, the better the AC performance.
