description

The ’FCT245T devices contain eight noninverting

bidirectional buffers with 3-state outputs and are

intended for bus-oriented applications.

The transmit/receive (T/R) input determines the direction of data flow through these bidirectional transceivers.

Transmit (active high) enables data from A ports to B ports. The output enable (OE), when high, disables both

the A and B ports by putting them in the high-impedance state.

These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the

outputs, preventing damaging current backflow through the device when it is powered down.
