description
These devices contain four independent 2-input
NAND 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. They may 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 VOH levels.
The SN54ALS01 is characterized for operation
over the full military temperature range of – 55
°C
to 125
°C. The SN74ALS01 is characterized for
operation from 0
°C to 70°C.
