description

These identity comparators perform comparisons

on two 8-bit binary or BCD words and provide

P = Q outputs. These devices have totem-pole

outputs.

The SN54ALS688 is characterized for operation

over the full military temperature range of –55 C°

to 125°C. The SN74ALS688 is characterized for

operation from 0°C to 70 C.°
