          DESCRIPTION:
          The IDT octal bidirectional transceivers are built using an
          advanced dual metal CMOS technology. The FCT245T/
          FCT2245T, FCT640T and FCT645T are designed for asyn-
          chronous 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-inverting outputs. The FCT640T has inverting outputs.
          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 FCT2xxxT parts
          are plug-in replacements for FCTxxxT parts.
