NSC DM64ALS08M Quad 2-input and gate Datasheet

DM64ALS08/DM74ALS08
Quad 2-Input AND Gate
Y
General Description
This device contains four independent gates, each of which
performs the logic AND function.
The DM64ALS08 version features the same performance
as the standard version DM74ALS08 with a guarantee over
an extended temperature range (b40§ C to a 85§ C).

Note: The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.
