AMD AmZ8121
The AmZ8121 is an 8-bit "equal to" comparator capable to comparing two 8-bit words for "equal to" with provision for expansion or external enabling. The matching of the two 8-bit inputs plus a logic LOW on the EIN produces an active LOW on the output EOUT. The logic expression for the device can be expressed as: EOUT = (AO (8 0) fA1 (8 1) (A2 (8 2) (A3 (83) (A4 0 B4) (AS 0 85) (A7 (87) EIN.| Part No. | AmZ8121 |

DESCRIPTION
It is obvious that the expression is valid where AO - A7 and BO - B7 are expressed as either assertions or negations. This is also true for pair of terms i.e. AO can be compared with BO at the same time 1\1 is compared with 81. It is only essential that the polarity of the paired terms be maintained.
