description
These identity comparators perform comparisons
on
two
8-bit
binary
or
BCD
words.
The
SN74ALS518 provides P = Q outputs, while the
′ALS520 and SN74ALS521 provide P = Q
outputs. The SN74ALS518 has an open-collector
output. The SN74ALS518 and
′ALS520 feature
20-k
pullup resistors on the Q inputs for analog
or switch data.
The SN54ALS520 is characterized for operation
over the full military temperature range of – 55
°C
to 125
°C. The SN74ALS518, SN74ALS520, and
SN74ALS521 are characterized for operation
from 0
°C to 70°C.
