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 multi- plexer circuits have individual active-LOW Enables (Ea, Eb) which can be used to strobe the outputs indepen- dently. When the Enables (Ea, Eb) are HIGH, the corre- sponding outputs (Za, Zb) are forced LOW. The VHC153 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 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 Select Inputs (a or b) Output Inputs S0 S1 E I0 I1 I2 I3 Z XX H XXXX L LLLL X X X L LLL H X X X H HL LXLX X L HL L XHX X H LHL X X L X L LHL X X H X H HH L XXX L L HH L XXX H H |
