NOTE:
TESTCONDITIONS:
1.tDF is defined as the time at which the output achieves the
open circuit condition and data is no longer driven.
• Inputpulselevels:0.45V/2.4Vfor70nsmax,0V/3Vfor
55ns
• Input rise and fall times: is equal to or less than 10ns
for 70ns max,5ns for 55ns
• Outputload:1TTLgate+100pF(Includingscopeand
jig) for 70ns max.
:1TTLgate+30pF for 55ns max.
• Reference levels for measuring timing: 0.8V, 2.0V for
70ns max.;1.5V for 55ns
