DM7403 Quad 2-Input NAND Gates with Open-Collector Outputs August 1986 Revised February 2000 DM7403 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 outputs require external pull-up resistors for proper logical operation.
Pull-Up Resistor Equations Where: N1 (IOH) = total maximum output high current for all outputs tied to pull-up resistor N2 (IIH) = total maximum input high current for all inputs tied to pull-up resistor N3 (IIL) = total maximum input low current for all inputs tied to pull-up resistor Ordering Code: Order Number DM7403N Package Number ...
