Absolute Maximum Ratings
(Note 1)
Note 1:
“Absolute Maximum Ratings” are those values beyond which the
safety of the device cannot be guaranteed. Except for “Operating Tempera-
ture Range” they are not meant to imply that the devices should be oper-
ated at these limits. The Electrical Characteristics tables provide conditions
for actual device operation.
DC Electrical Characteristics
Min/Max limits apply across the guaranteed temperature range unless otherwise noted
Note 2:
Only one of the six inputs is at V
CC
; the others are either at V
CC
or GND.
