| DUAL 4-INPUT MULTIPLEXER The SN54 / 74LS352 is a very high-speed Dual 4-input Multiplexer with Common Select inputs and individual Enable inputs for each section. It can select two bits of data from four sources. The two buffered outputs present data in the inverted (complementary) form. The SN54 / 74LS352 is the functional equivalent of the SN54 / 74LS153 except with inverted outputs.

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. Za = Ea * (I0a * S1 * S0 + I1a * S1 * S0 + I2a * S1 * S0 + I3a * S1 * S0) Zb = Eb * (I0b * S1 * S0 + I1b * S1 * S0 + I2b * S1 * S0 + I3b * S1 * S0) The SN54 / 74LS352 can be used to move data from a group of registers to a common output bus. The particular register from which the data came would be determined by the state of the Select Inputs. A less obvious application is a function generator. The SN54 / 74LS352 can generate two functions of three variables. This is useful for implementing highly irregular random logic.
