If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3)
Human body model, 100pF discharged through a 1.5k
Ω resistor.
(4)
Machine Model ESD test is covered by specification EIAJ IC-121-1981. A 200pF cap is charged to the specified voltage, then
discharged directly into the IC with no external series resistor (resistance of discharge path must be under 50
).
