TEST CONDITIONS:
• Input pulse levels: 0.45V/2.4V
• Input rise and fall times: < 10ns
• Output load: 1 TTL gate + 100pF (Including scope and jig)
• Reference levels for measuring timing: 0.8V, 2.0V
NOTE:
1. tDF is defined as the time at which the output achieves the
open circuit condition and data is no longer driven.
