DM74LS05
Hex Inverters with Open-Collector Outputs
General Description |
Pull-Up Resistor Equations |
This device contains six independent gates each of which performs the logic INVERT function. The open-collector outputs require external pull-up resistors for proper logical operation.
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

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.
