54LS03/DM54LS03/DM74LS03 Quad 2-Input NAND Gates with Open-Collector Outputs General Description Pull-Up Resistor Equations This device contains four independent gates each of which performs the logic NAND function. The open-collector outputs require external pull-up resistors for proper logical operation. Features Y Alternate Military/Aerospace device (54LS03) is available. Contact a National Semiconductor Sales Office/ Distributor for specifications.

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.
