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