(1) “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to
imply that the devices should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device
operation.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.

(1) Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground
except V_OD1/2/3and V_ID.
(2) All typicals are given for: V_CC = +5.0V, T_A = +25°C.
(3) Δ|V_OD| and Δ|V_OC| are changes in magnitude of V _OD and V_OC respectively, that occur when the input changes state.
