Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions above those indicated in the operational sec-
tions of this specification is not implied. Exposure
to absolute maximum rating conditions for extended
DC Electrical Characteristics
periods may affect reliability.
(V_CC = 1.2V to 5.5V, T_A= -40~85ºC, unless otherwise noted. Typical values are at T_A = +25ºC)
