IDT74FCT645T/AT/CT/DT
DESCRIPTION:
The IDT octal bidirectional transceivers are built using an advanced dual metal CMOS technology. The FCT645T 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.
