description

These identity comparators perform comparisons

on two 8-bit binary or BCD words. The

SN74ALS518 provides P = Q outputs, while the

鈥睞LS520

and SN74ALS521 provide P = Q

outputs. The SN74ALS518 has an open-collector

output. The SN74ALS518 and

鈥睞LS520

feature

20-k鈩?pullup resistors on the Q inputs for analog

or switch data.

The SN54ALS520 is characterized for operation

over the full military temperature range of 鈥?55擄C

to 125擄C. The SN74ALS518, SN74ALS520, and

SN74ALS521 are characterized for operation

from 0擄C to 70擄C.
