FUNCTIONAL DESCRIPTION
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 (...
