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.
