Outputs
General Description
The 鈥橣CT245 contains eight non-inverting bidirectional buff-
ers with TRI-STATE outputs and is intended for bus-oriented
applications. Current sinking capability is 48 mA on both the
A and B ports. The Transmit/Receive (T/R) input determines
the direction of data flow through the bidirectional trans-
ceiver. Transmit (active HIGH) enables data from A ports to B
ports; Receive (active LOW) enables data from B ports to A
ports. The Output Enable input, when HIGH, disables both A
and B ports by placing them in a High Z condition.
