ORDER CODES
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
application.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
