Functional Description
The SCAN182245A consists of two sets of nine non-invert-
ing bidirectional buffers with TRI-STATE outputs and is in-
tended 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 Output
Enable pins (G1 and G2) when HIGH disables both A and B
ports by placing them in a high impedance condition.
