description
These devices contain six independent inverters.
They perform the Boolean function Y = A 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 SN54HC05 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74HC05 is characterized for
operation from –40°C to 85°C.
