description
These devices contain six independent hex
inverters with open-collector outputs. They
perform the Boolean function Y = A
. The
open-collector outputs require pullup resistors to
perform correctly. These outputs can be con-
nected to other open-collector outputs to
implement active-low wired-OR or active-high
wired-AND functions. Open-collector devices are
often used to generate higher V
OH
levels.
The SN54ALS05A is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74ALS05A is characterized for
operation from 0°C to 70°C.
