MC74AC352, mc74act352 http://onsemi.com 2 functional description the MC74AC352/74act352 is a dual 4-input multiplexer. it selects two bits of data from up to four sources under the control of the common select inputs (s 0 , s 1 ). the two 4-input multiplexer circuits have individual active low enables (e a , e b ) which can be used to strobe the outputs independently. when the enables (e a , e b ) are high, the corresponding outputs (z a , z b ) are forced high. the logic equations for the outputs are shown below: z a = e a ? (i 0a ? s 1 ? s 0 +i 1a ? s 1 ? s 0 + i 2a ? s 1 ? s 0 +i 3a ? s 1 ? s 0 ) z b = e b ? (i 0b ? s 1 ? s 0 +i 1b ? s 1 ? s 0 + i 2b ? s 1 ? s 0 +i 3b ? s 1 ? s 0 ) the MC74AC352/74act352 can be used to move data from a group of registers to a common output bus. the particular register from which the date came would be determined by t he state of the select inputs. a less obvious application is as a function generator. the MC74AC352/ 74act352 can generate two functions of three variables. this is useful for implementing highly irregular random logic. e a i 0a i 3a s 0 s 0 i 0b i 1b i 2b i 3b e b z a z b logic diagram please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays. i 1a i 2a
