General Description

These 4-bit magnitude comparators perform comparison of straight binary or BCD codes. Three fully-decoded decisions about two, 4-bit words (A, B) are made and are externally available at three outputs. These devices are fully expandable to any number of bits without external gates.

Words of greater length may be compared by connecting comparators in cascade. The A > B, A

Features

■ Typical power dissipation 52 mW

■ Typical delay (4-bit words) 24 ns
