Meets or exceeds JEDEC standard 18 specifications Available in SOIC, and SSOP packages Std., A, C and D speed grades High drive outputs (-15mA IOH, 64mA IOL) 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.
