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 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:
