description
These devices contain six independent inverting
buffers. They perform the Boolean function Y = A
.
The open-collector outputs require pullup
resistors to perform correctly. These outputs can
be connected 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 SN54ALS1005 is characterized for operation
over the full military temperature range of −55°C
to 125°C. The SN74ALS1005 is characterized for
operation from 0°C to 70°C.
