The IDT octal bidirectional transceivers are built using an advanced dual
metal CMOS technology. The FCT245 is designed for asynchronous twoway communication between data buses. The transmit/receive (T/R) input
determines the direction of data flow through the bidirectional transceiver.
Transmit (active high) enables data from A ports to B ports, and receive
(active low) from B ports to A ports. The output enable (OE) input, when
high, disables both A and B ports by placing them in High-Z condition.
The FCT245 transceivers have non-inverting outputs.
