STMicroelectronics HCF4585B

The HCC4585B (extended temperature range) and HCF4585B (intermediate temperature range) are monolithic integrated circuits, available in 16-lead dual in-line plastic or ceramic package, and plastic micro package. The HCC/HCF4585B is a 4-bit magnitude comparator designed for use in computer and logic applications that require the comparison of two 4-bit words.

DESCRIPTION

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 HCC/HCF4585B 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) that permit systems designers to expand the comparator function to 8, 12, 16 ... 4 N bits. When a single HCC/HCF4585B is used, the cascading inputs are connected as follows : (A < B) = low, (A = B) = high, (A > B) = high. Cascading these units for comparison of more than 4 bits is accomplished as shown in typical application. June 1989 1/12 HCC/HCF4585B FUNCTIONAL DIAGRAM
