Small-Outline (D) Packages, Ceramic Chip
Carriers (FK), and Standard Plastic (N) and
Ceramic (J) 300-mil DIPs
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.
