DESCRIPTION:
•
•
•
•
The IDT octal bidirectional transceivers are built using an advanced dual
metal CMOS technology. The FCT245T 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.
