description
These devices contain four independent 2-input
positive-NAND buffers. They perform the Boolean
functions Y = A
B or Y = A + B in positive logic.
The SN54ALS37A is characterized for operation
over the full military temperature range of –55
°
C
to 125
°
C. The SN74ALS37A is characterized for
operation from 0
°
C to 70
°
C.
