The FCT245T/ FCT2245T, FCT640T and FCT645T are 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. The FCT245T/FCT2245T and FCT645T transceivers have non-inver...
