4-Bit Magnitude Comparator

General Description

Features

These 4-bit magnitude comparators perform comparison of

straight binary or BCD codes. Three fully-decoded deci-

sions about two, 4-bit words (A, B) are made and are exter-

nally 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 < B, and A = B out-

puts of a stage handling less-significant bits are connected

to the corresponding inputs of the next stage handling

more-significant bits. The stage handling the least-

significant bits must have a high-level voltage applied to

the A = B input. The cascading path is implemented with

only a two-gate-level delay to reduce overall comparison

times for long words.

■ Typical power dissipation 52 mW

■ Typical delay (4-bit words) 24 ns
