FAST CMOS OCTAL

BIDIRECTIONAL

TRANSCEIVER

DESCRIPTION:

The IDT octal bidirectional transceivers are built using an advanced dual

metal CMOS technology. The FCT2245T 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 trans-

ceiver. 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 FCT2245T has balanced drive outputs with current limiting resistors.

This offers low ground bounce, minimal undershoot and controlled output

fall times- reducing the need for external series terminating resistors. The

FCT2245T parts are plug-in replacements for FCT245T parts.
