description

These devices contain four independent 2-input

positive-AND gates. They perform the Boolean

functions Y = A

• B or Y = A + B in positive logic.

The

open-collector

outputs

require

pullup

resistors to perform correctly. These outputs may

be connected to other open-collector outputs to

implement active-low wired-OR or active-high

wired-AND functions. Open-collector devices are

The SN54ALS09 is characterized for operation

over the full military temperature range of – 55

°C

to 125

°C. The SN74ALS09 is characterized for

operation from 0

°C to 70°C.
