54LS03 DM54LS03 DM74LS03
Quad 2-Input NAND Gates
with Open-Collector Outputs
General Description
This device contains four independent gates each of which
performs the logic NAND function The open-collector out-
puts require external pull-up resistors for proper logical op-
eration

Note
The ``Absolute Maximum Ratings'' are those values
beyond which the safety of the device cannot be guaran-
teed 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
