Quad 2 Input Multiplexer With TRI - STATE Outputs
General Description
The AC257 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 true (noninverted) form. The outputs may be switched to a high impedance
state by placing a logic HIGH on the common Output Enable (OE) input, allowing the outputs
to interface directly with bus-oriented systems.
