Switching Characteristics

Notes:

6. Device is considered as a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are

shorted together.

7. Common mode transient immunity at output high is the maximum tolerable (positive) dVcm/dt on the leading edge

of the common mode impulse signal, Vcm, to assure that the output will remain high. Common mode transient

immunity at output low is the maximum tolerable (negative) dVcm/dt on the trailing edge of the common pulse

signal,Vcm, to assure that the output will remain low.
