MOTOROLA MC74AC353 Dual 4-input multiplexer with 3-state output Datasheet

DUAL 4-INPUT
MULTIPLEXER WITH
3-STATE OUTPUTS
The MC74AC353/74ACT353 is a dual 4-input multiplexer with 3-state outputs.
It can select two bits of data from four sources using common Select inputs. The
outputs may be individually switched to a high impedance state with a HIGH on the
respective Output Enable (OE) inputs, allowing the outputs to interface directly with
bus-oriented systems.

FUNCTIONAL DESCRIPTION
The MC74AC353/74ACT353 contains two identical
4-input multiplexers with 3-state outputs. They select two bits
from four sources selected by common Select inputs (S0, S1).
The 4-input multiplexers have individual Output Enable (OEa,
OEb) inputs which, when HIGH, force the outputs to a high
impedance (High 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.
Za = OEa•(I0a•S1•S0+I1a•S1•S0+
I2a•S1•S0+I3a•S1•S0)
Zb = OEb•(I0b•S1•S0+I1b•S1•S0+
I2b•S1•S0+I3b•S1•S0)
