Logic Symbol S0 S1 Ea I0a I1a I2a I3a Za Zb I0b I1b I2b I3b Eb FUNCTIONAL DESCRIPTION The MC74AC153/74ACT153 is a dual 4−input multiplexer. It can select 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 LOW. The MC74AC153/74ACT153 is the logic implementation of a 2−pole, 4−position switch, where the position of the switch is determined by the logic levels supplied to the two Select inputs. 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) Ea I0a I3a S1 S0 I0b I1b I2b I3b Eb Za Zb Figure 3.
