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 (S0, S1). The two 4-input

multiplexer circuits have individual active LOW Enables (Ea,

Eb) which can be used to strobe the outputs independently.

When the Enables (Ea, Eb) are HIGH, the corresponding

outputs (Za, Zb) are forced HIGH.

The logic equations for the outputs are shown below:

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 the 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.
