DM74LS03 Quad 2-Input NAND Gates with Open-Collector Outputs 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 operation. Pull-Up Resistor Equations Where: N 1 (IOH ) = total maximum output high current for all outputs tied to pull-up resistor N 2 (IIH) = total maximum input high current for all inputs tied to pull-up resistor N 3 (IIL) = total maximum input low current for all inputs tied to pull-up resistor Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Absolute Maximum Ratings(Note 1) Note 1: 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 tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Recommended Operating Conditions
