or 
in positive
logic. The open-drain outputs require pullup resistors to perform
correctly. They may be connected to other open-drain outputs to
implement active-low wired-OR or active-high wired-AND functions.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of TexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
These devices contain four independent 2-input NAND gates. They
perform the Boolean function or in positive
logic. The open-drain outputs require pullup resistors to perform
correctly. They may be connected to other open-drain outputs to
implement active-low wired-OR or active-high wired-AND functions.
The SN54HC03 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74HC03 is characterized for operation from -40°C to 85°C.
