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.
