Notes:
7. Data rate is based on 10MHz, 50% NRZ pattern with a 50nsec minimum bit time.
8. t_PSK is equal to the magnitude of the worst case difference in t_PHL and/or t_PLH that will be seen between any two units
from the same manufacturing date code that are operated at same case temperature (±5°C), at same operating
conditions, with equal loads (R_L = 350Ω and C_L = 15pF), and with an input rise time less than 5ns.
9. 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.
10.Unloaded dynamic power dissipation is calculated as follows: C_PD x V_DD x f + I_DD + V_PD where f is switched
time in MHz.
