Notes:
9. tPHL propagation delay is measured from the 50% level on the falling edge of the input pulse to the 50% level of the
falling edge of the VO signal.
10. tPLH propagation delay is measured from the 50% level on the rising edge of the input pulse to the 50% level of the
rising edge of the VO signal.
11. PWD is defined as | tPHL – tPLH | for any given device.
12. The difference between tPHL and tPLH between any two FOD8320 parts under same operating conditions, with equal
loads.
13. Common mode transient immunity at output high is the maximum tolerable negative dVcm/dt on the trailing edge of
the common mode impulse signal, Vcm, to assure that the output will remain high (i.e. VO > 15.0V).
14. Common mode transient immunity at output low is the maximum tolerable positive dVcm/dt on the leading edge of
the common pulse signal, Vcm, to assure that the output will remain low (i.e. VO < 1.0V).
