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) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not
apply when operating the device beyond its specified operating ratings.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(3) Human body model, 100 pF discharge through a 1.5 kΩ resistor.
(4) The maximum power dissipation is a function of T_Jmax, θ_JA, and T_A. The maximum allowable power dissipation at any ambient
temperature is P_D = (T_Jmax − T_A)/θ_JA. If this dissipation is exceeded, the die temperature will rise above 150°C and the SM74501 will go
into thermal shutdown.

(1) Datasheet min/max specification limits are specified by design, test, or statistical analysis.
(2) Typicals are at 25°C (unless otherwise specified) and represent the most likely parametric norm.
(3) To ensure constant junction temperature, pulse testing is used.
