FACT DATA
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.
