The HCF4063B is a low power 4-bit magnitude comparator designed for use in computer and logic applications that require the comparison of two 4-bit words. This logic circuit determines whether one 4-bit word (Binary or BCD) is "less than", "equal to" or "greater than" a second 4 bit word. The HCF4063B has eight comparing inputs (A3, B3 through A0, B0), three outputs (A<B, A=B, A>B) and three cascading inputs (A<B, A=B, A>B) DIP SOP ORDER CODES PACKAGE TUBE T&R DIP SOP HCF4063BEY HCF4063BM1 HCF4063M013TR that permit system s designers to expand the comparator function to 8, 12, 16...4N bits. When a single HCF4063B is used the cascading inputs are connected as follows : (A<B) = low, (A=B) = high, (A>B) = low. For words longer than 4 bits, HCF4063B device may be cascaded by connecting the outputs of the less-significant comparator to the corresponding cascading inputs of the more significant comparator. Cascading inputs (A<B, A=B, and A>B) on the least significant comparator are connected to a low, a high, and a low level, respectively.
