NOTE:
1. Not 100% tested.
TEST CONDITIONS:
• Input pulse levels: 0V/3.0V.
2. tDF is defined as the time at which the output achieves
the open circuit condition and data is no longer driven.
• Input rise and fall times is equal to or less than 5ns.
• Outputload:1TTLgate+100pF(Includingscopeand
jig), for29LV400T/B-90. 1TTL gate+30pF(Including
scopeandjig)for29LV400T/B-70&29LV400T/B-55R.
• Reference levels for measuring timing: 1.5V.
