DESCRIPTION

· The HCF4063B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology, available in DIP and SOP packages.

· It is a low power 4-bit magnitude comparator designed for 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.

FEATURES

· Quiescent current specified up to 20V.

· Standard B-series output drive.

· Expansion to 8-16...4N bits by cascading unit.

· Medium speed operation: compares two 4-bit words in 250ns (Typ.) at 10V.

· 5V, 10V, and 15V parametric ratings.

· Input leakage current II = 100nA (MAX) at VDD = 18V, TA = 25°C.

· 100% tested for quiescent current.

· Meets all requirements of JEDEC JESD13B "Standard Specifications for Description of B Series CMOS Devices".

APPLICATIONS

· Computer and logic applications requiring the comparison of two 4-bit words.

· Systems where expansion to 8, 12, 16...4N bits is necessary by cascading multiple HCF4063B devices.
