AmZ8121 - 8-Bit Equal-To Comparator

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.

AmZ8121 Eight-Bit Equal-To Comparator DISTINCTIVE CHARACTERISTICS • 8-bit byte oriented equal-to comparator • Cascadable using EIN • High-speed, Low-Power Schottky technology • tpd A0 8 to ~OUT in 9ns • Standard 20-pin package • 100% product assurance screening to MIL-STD-883 requirements 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 (87) EIN.
