IDT54/74FCT2245T/AT/CT
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.
