Functional Description
This device is a logical implementation of a single-pole 8-
position switch with the switch position controlled by the
state of three Select inputs S0 S1 S2 Both assertion and
negation outputs are provided The Output Enable input
(OE) is active LOW When it is activated the logic function
provided at the output is
Z e OE
(I0S0S1 S2 a I1S0S1S2 a
I2S0S1S2 a I3S0S1S2 a
I4S0S1S2 a I5S0S1S2 a
I6S0S1S2 a I7S0S1S2)
When the Output Enable is HIGH both outputs are in the
high impedance (High Z) state This feature allows multi-
plexer expansion by tying the outputs of up to 128 devices
together When the outputs of the TRI-STATE devices are
tied together all but one device must be in the high imped-
ance state to avoid high currents that would exceed the
maximum ratings The Output Enable signals should be de-
signed to ensure there is no overlap in the active LOW por-
tion of the enable voltages
