DC Characteristics 2
Notes 1.
I
CC1
depends on output loading and cycle rates. Specified values are obtained with the
output open. In addition to this, I
CC1
is measured on condition that addresses are
changed only one time during t
CK (MIN.)
.
I
CC4
depends on output loading and cycle rates. Specified values are obtained with the
output open. In addition to this, I
CC4
is measured on condition that addresses are
changed only one time during t
CK (MIN.)
.
I
CC5
is measured on condition that addresses are changed only one time during t
CK
(MIN.)
