4-bit Magnitude parator
REJ03D0421- 0200 Rev.2.00
Feb.18.2005
This four bit magnitude parator performs parison of straight binary and straight BCD (8-4-2-1) codes. Three fully decoded decisions about two 4-bit words (A, B) are made and are externally available at three outputs. This device is fully expandable to any number of bits without external gates. Words of greater length may be pared by connecting parators in cascade. The A > B, A < B, and A = B outputs of a stage handling less-significant bits. The stage handling the least- significant bits must have a high-level voltage applied to the A β B input. The cascading path is implemented with only a two-gate-level delay to reduce overall parison times for long words.
