Quad 2 Input Multiplexer With TRI - STATE Outputs
General Description
The AC258 is a quad 2-input multiplexer with 3-state outputs. Four bits of data from two
sources can be selected using a Common Data Select Input. The four outputs present the
selected data in the complement (inverted) form. The outputs may be switched to a high
impedance state with a logic HIGH on the common Output Enable (OE) input, allowing the
outputs to interface directly with bus-oriented systems.
