The Renesas Electronics IDT octal bidirectional transceivers are built using an advanced dual metal CMOS technology. The FCT245T is designed for asynchronous two-way 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. CMOS power levels
