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.
