FACT DATA
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.
