8-Bit Identity Comparators With Open-Collector Outputs
Package Options Include PlasticSmall-Outline (DW) Packages, Ceramic
Chip Carriers (FK), and Standard Plastic (N)
and Ceramic (J) 300-mil DIPs‡SN74ALS521 is identical to ′ALS688.
descriptionThese 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-kΩ 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.
