DESCRIPTION:

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/

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 (

input, when HIGH, disables both A and B ports by placing

them in HIGH Z condition.

non-inverting outputs. The FCT640T has inverting outputs.

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.
