1. Test conditions: Input pulse levels - 0.4V to 2.4V; input rise and fall times < 20ns; output load - 1 TTL gate + 100pF (including
scope and jig); reference levels for measuring timing - 0.8V/1.8V.
2. tDF and tDFR are defined as the time at which the output becomes an open circuit and data is no longer driven.
3. Guaranteed by design.
