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

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.
