13.Test conditions shown in (a) of AC Test Loads, unless otherwise noted.
14.This part has a voltage regulator internally; t

to eliminate bus contention between SRAMs when sharing the same
data bus. These specifications do not imply a bus contention condition, but reflect parameters guaranteed over worst case user conditions. Device is designed
to achieve Three-state prior to Low-Z under the same system conditions
