Functional Description
The SCAN182245A consists of two sets of nine non-invert-
ing bidirectional buffers with 3-STATE outputs and is
intended for bus-oriented applications. Direction pins (DIR1
and DIR2) LOW enables data from B Ports to A Ports,
when HIGH enables data from A Ports to B Ports. The Out-
put Enable pins (G1 and G2) when HIGH disables both A
and B Ports by placing them in a high impedance condition.
