COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; functional operation of the
device (at these or any other conditions above those indi-
cated in the operational sections of this specification) is
not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.

Test Conditions
CE = OE = V_IL, WE = V_IH, All I/O’s = open,
address inputs = .4V/2.4V levels @ f = 10MHz
CE = V_IH, OE = V_IL, All I/O’s = open, other
inputs = V_IH
CE = V_CC - 0.3V, OE = GND, All I/Os = open,
other inputs = V_CC - 0.3V
V_IN = V_SS to V_CC
V_OUT = V_SS to V_CC, CE = V_IH
I_OL = 6mA
I_OH = -4mA
Notes: (1) Typical values are for T_A = 25°C and nominal supply voltage.
(2) V_IL min. and V_IH max. are for reference only and are not tested.
