Functional Description
This device contains two identical 4-input multiplexers with
TRI-STATE outputs They select two bits from four sources
selected by common Select inputs (S0 S1) The 4-input mul-
tiplexers have individual Output Enable (OEa OEb) inputs
which when HIGH force the outputs to a high impedance
(High Z) state This device 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 e OEa  (I0a  S1  S0 a I1a  S1  S0 a
I2a  S1  S0 a I3a  S1  S0)
Zb e OEb  (I0b  S1  S0 a I1b  S1  S0 a
I2b  S1  S0 a I3b  S1  S0)
If the outputs of TRI-STATE devices are tied together all
but one device must be in the high impedance state to avoid
high currents that would exceed the maximum ratings De-
signers should ensure that Output Enable signals to TRI-
STATE devices whose outputs are tied together are de-
signed so that there is no overlap
