DEFINITIONS
V
IH
V
is the d.c. input level above which an
input level is guaranteed to appear as a
logical one. This parameter is to be
measured by performing a functional
test at reduced clock speeds and nomi-
nal timing, (i.e. not minimum setup and
hold times or output strobes), with the
high level of all driving signals set to V
IH
and maximum supply voltages applied
to the device.
V
IL
V
is the d.c. input level below which an
input level is guaranteed to appear as a
logical zero to the device. This param-
eter is measured in the same manner as
V
but with all driving signal low levels
set to V
and minimum supply voltages
applied to the device.
V
is the minimum d.c. output level to
which an output placed in a logical one
state will converge when loaded at the
maximum specified load current.
