HD74HC682/HD74HC684
8-bit Magnitude Comparator
Description
These magnitude comparators perform comparisons of two eight-bit binary or BCD words. All types
provide
P=Q
outputs and provide
P>Q
outputs. The HD74HC682 features 20 k pullup termination
resistors on the Q inputs for analog or switch data.
