4-Bit Magnitude Comparators

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 expand-

able to any number of bits without external gates. Words of

greater length may be compared by connecting compara-

have a high-level voltage applied to the A

B input. The

cascading paths are implemented with only a two-gate-level

delay to reduce overall comparison times for long words.

Features

Typical power dissipation 275 mW

tors in cascade. The A B, A B, and A

B outputs of a

Typical delay (4-bit words) 23 ns

stage handling less-significant bits are connected to the cor-

responding inputs of the next stage handling more-signifi-

cant bits. The stage handling the least-significant bits must

Alternate Military/Aerospace device (5485) is available.
