MC54/74F353
DUAL 4-INPUT MULTIPLEXER
WITH 3-STATE OUTPUTS
The MC54/74F353 is a dual 4-input multiplexer with 3-state outputs. It can
selecttwobitsofdatafromfoursourcesusingcommonSelectinputs. Theout-
puts may be individually switched to a high impedance state with a HIGH on
the respective Output Enable (OE) inputs, allowing the outputs to interface di-
rectly with bus-oriented systems.

FUNCTIONAL DESCRIPTION

1
The MC54/74F353 contains two identical 4-input multiplexers with 3-state
outputs. They select two bits from four sources selected by common Select
inputs (S , S ).The 4-input multiplexers have individual Output enable (OE ,
0

a
OE ) inputs which, when HIGH, force the outputs to a high impedance (high
b
Z) state. The logic equations for the outputs are shown below:

If the outputs of 3-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. Designers should ensure that Output Enable signals to
3-state devices whose outputs are tied together are designed so that there is
no overlap.
