Notes:
(1)
Stresses greater than listed under “Absolute Maximum Ratings” may cause permanent damage to the
device.
All voltages are reference to GND.
I
DDO
depends on the cycle time.
I
DDO
depends on output loading. Specified values are defined with the output open condition.
AC measurements are assumed t
R
, t
F
=
5 ns.
Parameters t
OD
, t
ODO
, t
BD
and t
ODW
define the time at which the output goes the open condition and
are not output voltage reference levels.
Data cannot be retained at deep power-down stand-by mode.
If OE is high during the write cycle, the outputs will remain at high impedance.
During the output state of I/O signals, input signals of reverse polarity must not be applied.
If CE1 or LB/ UB goes LOW coincident with or after WE goes LOW, the outputs will remain at high
impedance.
If CE1 or LB/ UB goes HIGH coincident with or before WE goes HIGH, the outputs will remain at
high impedance.
