2 / 7 page www.fairchildsemi.com 2 Functional Description The VHC153 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 VHC153 is the logic implementa- tion of a 2-pole, 4-position switch, where the position of the switch is determined by the logic levels supplied to the 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) Truth Table H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial 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.
