This comparator compares two 4-bit words and

provides an high voltage level on one of the A>B

out, A=B out and A<B out outputs. The comparing

bit number is easily expanded by cascading

several devices as shown in the typical

application.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
